Backing up is nice, restoring is better. Slow backups, mean slow restores. Make good decisions, and backup only the files you want to keep to the fastest storage you have.
When working with a fast fibre channel or Thunderbolt SAN your first choice for fastest backup destinations is a Thunderbolt RAID. I recommend to have this onsite with an off site LTO and/or cloud disaster recovery setup (a replicated SAN or shared storage system is nice to have too).
A built-in option to copy Xsan files is cvcp (cv stands for centravision).
cvcp is fast. Really fast. And cli commands are scriptable. A very smart person (Jasper Siegers) wrote a script called cvcpSync which combined the power of rsync and cvcp. It was awesome. But there are limits to the best of scripts. For my clients I use Archiware P5 with large SAN and other shared storage to simplify the number of things which need to be monitored. One dashboard to monitor tape or cloud backups, tape archives and sync to nearline RAIDs or NAS.
With a recently Thunderbolt SAN deployment with Accusys T-Share I set up the Accusys Gamma Carry as a backup destination. I set up Archiware P5 to do the backup. It was fast. How fast? Over 1Gb/s. Fast backups are also fast restores. With the Gamma Carry I can run a backup then carry it off site. It’s an option as part of a complete backup strategy.
Archiware P5 backup 1.6TB in 53 minutes
(Luckily I have almost 2 TB of video from my Cycliq bike cameras to test backups. Sadly, after my last bike vs car incident I felt obliged to buy bike cameras for my safety. I edit small fun rides when I can. Sometimes traffic near-accidents too. Please be kind, don’t kill cyclists.)
Archiware P5 backup of a Thunderbolt SAN to a Thunderbolt Gamma Carry RAID
Note: In my tests I tested backup to a nearline RAID. I also like to use tape drives. LTO tape is another recommended option for backups or archives. Cloud or other offsite replication is also recommended if possible but is the slowest of all the options. Good to have slow and fast options, offsite and on premise, though any practical solution should be affordable and useful to help decision makers take the steps to preserve data and ultimately their own business.
LTO vs Cloud backup comparison: For LTO backups to one LTO7 drive I normally see 1TB in under 2 hours versus some recent cloud backups I did using rclone which took 9 hours for 1TB. Remember: restore times will equal your backup times. Want to restore 100TB? Got a spare 900 hours? 38 days for cloud restore vs 8 days with one LTO7 drive (much faster if you have more than one drive). Even faster if you restore from a Thunderbolt RAID. Only 2.5 days. Think about it.
Thunderbolt Xsan in a box. I’ve written about the Accusys T-share in 2020 (and in 2015 when I first found this cool tech). What’s different now? New year, new macOS. And a new challenge: can we build Xsan only using Terminal? No apps. It’s the journey that counts, right? One nerd’s journey to make an Xsan with macOS 11 Big Sur cli. Destination adventure with family fun, next stop a blinking cursor on a command line prompt.
make Xsan
make —Xsan —-bigger
reboot
Sudo make me an Xsan sandwich. I wish it were that easy! Stick around for the two or three commands you do need.
Xsan goes Terminal
Important commands for using Xsan have always been cvadmin and cvlabel (cv is short for centravision the original creators) but more recently xsanctl and slapconfig are important for creating the SAN and the OD (Open Directory) environment. Read the man pages, search the web, read some help documents. This blog is for entertainment and occasional learnings.
Lots of interesting cv (CentraVision) and sn (StorNext) commands in macOS (this list is from 10.15 Catalina). Besides binaries, what else is there? Examples. A ton of example files:
If you don’t have a fibre channel switch and fibre channel hardware RAIDs do not worry. You can build a useful Thunderbolt based Xsan with a little bit of effort. Just a little bit of peril It’s not too perilous, don’t worry.
Apple includes Xsan for free in macOS. Xsan is Apple’s fork Quantum’s StorNext SAN software. Want large fast storage made for Final Cut Pro editors, just add Xsan. Download Server.app from the Mac App Store and make your Xsan. Easy peasey. Right?
Why? Why are we doing this? Nothing beats fibre channel or Thunderbolt SAN speed for editing. Network attached storage (NAS) at 1GbE is barely usable. NAS at 10GbE is much better but still has road blocks for editors. Fibre channel or Thunderbolt with a big enough raid behind your SAN then life is great. Xsan can be shared by a small or media sized team of editors, producers and assistants.
Oh, ok. There is one problem. Apple did a major upgrade of Xsan (now version 7!) in macOS 11 Big Sur but apparently they took out the Xsan config in Server.app. (Note: This is what I was told early on and what seemed to be confirmed by Apple’s recent Xsan cli guide. It turns out that Xsan’s disappearance in Server.app to not be totally correct). Xsan is there in Server.app if you upgrade to macOS Big Sur but when you install Server on a clean macOS there is no Xsan visible in the app. Hmm. What do we do? Apple published a very nice handy guide about how to build Xsan in Terminal. So let’s get started. This is fun.
Accusys T-Share is a Thunderbolt SAN. Connect Macs with Thunderbolt cable.
What do we need? 1) Hardware raid. Ok check I have an Accusys T-Share. It’s a raid with Thunderbolt switch built in. 2) Mac. Ok I have a Mac Mini. 3) A network. Some cables, a switch and a DNS server. Ok I have a new raspberry Pi. That’s perfect.
Raspberry Pi 400 (the amazing linux computer shaped like a keyboard).
Step 1. Hardware raid. With the Accusys T-Share I just have to plug in some clients with a Thunderbolt 3 cable. Let’s fill the RAID with drives. I picked two different sizes. One group of larger disks for a data LUN (main production storage) and two smaller disks for a raid mirror to be used as metadata storage.
Step 2. A Mac running macOS Big Sur 11.5.2. Download the Accusys Mac installer on your Intel Mac (M1 is not supported with the T-Share yet as of this blog post).
Step 3. The network. Ok. This is the fun part. Let’s set up a DNS server. Ok, how do we do that? Remember that raspberry Pi you bought yourself for Christmas but never opened because you have been so busy and well you know life. Ok just me? Well, that one. Let’s use a raspberry Pi. A small inexpensive Linux computer. Install dns masq. It’s perfect for this.
The raid. Not only a great movie it’s the central part of this production media network for creatives. Once the drives are in the raid we have to make raid sets which become LUNs for Xsan. RAID5/6 for the data LUN and RAID1 (mirror) for the metadata LUN.
Read the label. Using Xsan cvlabel
Normally after we create RAID sets in the hardware raid utility we would open up Server.app and label the LUNs for Xsan use. But since we are now hardcore SAN architects we can use Terminal and the cvlabel the command to do this the hard way. Well, it’s not that hard but it can be intimidating the first few times. It’s much easier to label new LUNs than stare at a broken production SAN that has lost its labels. StorNext fun times. More about in another blog post.
Whether using Server.app in the good old days or cvlabel to label your LUNs now you should all be familiar with the command to list available LUNs. For larger SANs that won’t mount the first thing I’d check is see if the LUNs are all there. You don’t want a SAN to mount if it’s missing an important piece of itself.
cvlabel -l
This command lists available LUNs. It’s handy to know. Do this before trouble arises and you will be a cool dude when trouble happens. It does that occasionally. Prepare for the worst, hope for the best, IT motto.
To create labels for newly created RAID arrays use cvlabel to output a text file of the unlabelled LUNs, make some minor changes then label those LUNs. Create the template files first:
cvlabel -c
Edit the file. I like nano. Maybe you like vim. Or BBEdit. Or text edit. Change the name of LUNs from CVFS_unknown to whatever you like. I like to name LUNs based on the hardware they originate from so that I can find them, remove them, fix them or whatever I need to do for troubleshooting. Trust me. It’s a good idea.
cvlabel ~/Desktop/cvlabel
*WARNING* This program will over-write volume labels on the devices specified in the file "/Users/xavier/Desktop/cvlabel". After execution, the devices will only be usable by the Xsan. You will have to re-partition the devices to use them on a different file system.
Do you want to proceed? (Y / N) ->
Requesting disk rescan .
Congratulations this is the hardest part. You’ve labeled the RAID arrays as usable LUNs for Xsan. Ok, just kidding that’s not the hardest part. Have you ever heard of Open Directory? Do you fear LDAP and DNS? Well, maybe you should. It’s always DNS. Just saying.
DNS (domain name system) is just a fancy word for a list of IP addresses and host names. Using the raspberry Pi with dns masq installed we can populate the list of hosts for the Xsan and then we are golden. Hopefully if we did it right. Turns out we can make mistakes here too. Don’t use “.local” domain names. I did. It was late. I blame being tired. Changing them to “.lan” worked better.
Next up we finally create an Xsan in terminal. Or do we? let’s check the hostname first. It’s always DNS.
scutil —get HostName
CrazyMac.local
scutil --set HostName XsanMac.lan.
And now we make very big Xsan using the Xsan guide example
It was at this point that it started falling apart. It was late. I had messed up my DNS with “.local” and the Xsan wouldn’t go past this basic OD setup. I did what I always do and reach out to my Xsan colleagues and I got some curious feedback. “What do you mean Xsan isn’t in macOS Big Sur Server.app?” Hmm. I don’t see it on a fresh install. On an upgrade from 10.15 Catalina I do. So, uh, Where is it? And then it was revealed. In the View menu. Advanced. Ugh. It’s right there. Almost staring right at me. When I opened the app it said it couldn’t create an Xsan with my “.local”. That was helpful. Fixed that and Xsan with my pre-labeled LUNs was super quick to set up.
Xsan configuration in Server.app. “Ignore ownership” is the best thing ever for creatives. Trust me,
I’ll have to play with the cli set up again soon. Because there were some strange formatting it recommended to me when I tried some variations of the xsanctl createSan. I’ll dig into another day when I have more sleep. Ha ha.
There’s a lot of useful commands in macOS Big Sur Xsan which was upgraded to v7. You can check which version of Xsan you have in macOS with the cvversions command.
In Catalina (macOS 10.15.7)

There’s a lot of cool new binaries in Xsan v7. We will dig into those next post. For now enjoy this and go forth make some Xsan volumes with Thunderbolt or fibre channel storage. It’s fun.
Friends don’t let friends install macOS High Sierra in production. Don’t get High, Sierra.
macOS 10.13 was released on Sep 25, 2017, and almost two months later with only one point release update, it’s still too new for production. Download it on a test machine or two or more, test it with your apps and systems, file bug reports and radars, but for the love of all that is Python and Monty! don’t run it on your production Xsan. Well, at least not yet. Wait until next year. Or as long as you can. Or until the new iMac Pro is released with 10.13 pre-installed or wait until they ship the new Final Cut Pro X 10.4 that may or may not require macOS High Sierra.
With that out of the way, I’ve just upgraded the production Xsan to … macOS Sierra. Yes, macOS 10.12.6 is stable and it’s a good time to install last year’s macOS release. Time to say good bye to macOS el Capitan 10.11.6, we hardly knew ya. Besides guaranteed security updates, stability and the annoying newness of a changed macOS, what else is there? In Xsan v5 they introduced a new “ignore permissions” checkbox for your Xsan volumes. Looking forward to that feature in production. No more Munki onDemand nopkg scripts to run chmod. No more tech support requests for folders, files, FCP X projects that won’t open because someone else used it, owns it, touched it. We’ll see how that pans out. I’ll let you know.
Upgrading Xsan to v5
Step 1. Back up your data
You’re doing this, right? I’m using Archiware P5 Backup to backup the current projects to LTO tape. I’m using Archiware P5 sync to sync the current Xsan volumes to Thunderbolt RAIDs, and using Archiware P5 Archive (and Archive app) to archive completed projects to the LTO project archive. That’s all I need to do, right?
Step 2. Back up your servers
Don’t forget the servers running your SAN! I use Apple’s Time Machine to backup my Mac Mini Xsan controllers. External USB3 drive. I also use another Mac Mini in target disk mode with Carbon Copy Cloner to clone the server nightly. (Hat tip to Alex Narvey, a real Canadian hero). And of course I grab the Xsan config with hdiutil and all the logs with cvgather. Because, why not?! For Archiware P5 backup server I also have a python scripts to backup everything, another scripts to export a readable list of tapes, and BackupMinder to rotate the backups. Add some rsync scripts and you’re golden.
Step 3. Upgrade the OS
Unmount the Xsan volume on your clients or shut them down, disconnect the fibre channel. Do something like that. Stop your volume. Download the macOS Sierra installer from the App Store. Double click upgrade. Wait. Or use Munki. I loaded in the macOS 10.12.6 installer app into Munki and set it up as an optional install to make this portion of the upgrade much quicker and cleaner.
In my case after the OS was upgraded I checked the App Store app for any Apple updates (you can also use Munki’s Managed Software Center to check) and of course there were some security updates. In this case the security upgrade hung on a slow network connection and the server crashed. Server down! I had to restore from Time Machine backup to the point where I just upgraded the server. It took some extra time but it worked (can’t wait for next year’s mature APFS / Time Machine and restoring from snapshots instead).
Step 4. Upgrade Server
After macOS is upgraded you’ll need to upgrade the Server.app or just upgrade the services used by Server (even those not used by Server get upgraded).
Step 5. Upgrade the Xsan
Bur first we have to restore the Xsan config. Don’t panic! It may invoke bad memories of data loss and restoring from backups. Xsan PTSD is real.
Step 6. Upgrade the rest
Next you have to upgrade the Xsan volumes.
New version of Xsan, ch-ch-changes! Ignore permissions check box will remount the xsan with the “no-owners” flag. Let’s test this out.
Upgrade the OS and Server app on the backup controller. Upgrade the OS on the clients using Munki or App Store if you like doing it the hard way. Ha Ha.
Step 7. Enjoy
Plug those Thunderbolt to Fibre adapters back in, mount those Xsan volumes and be happy.
Step 8. Wait for the complaints
The next day the editors walked in and went straight to work with Final Cut Pro X. No one noticed anything. Xsan upgraded. Workstation macOS upgraded. Everything appeared to be the same and just worked. Thankless task but well worth it.
It was a dark and stormy night of cables and capacitors when suddenly I heard the door knocking, or was something falling of a shelf? I was in a cramped server room, if you’d call it that, and I was day dreaming, sorry, night terrorizing, of days gone past when I worked in nice big well ventilated server rooms with proper enterprise gear. Oh wait, did I really dream that? Did it really happen? Maybe it was less well ventilated and there were cables strewn about the tall 42U shelves and sometimes we found a Mac hidden underneath spaghetti. Sometimes. I vaguely remember the long shiny metal servers, they talked to me, they sang, a whiny pitch of whale song. Dream on, dream on.
Now. Today. Apple Music on my iPhone plays every single Arcade Fire album in a long playlist, in order. And I follow the white rabbit of Thunderbolt cables. This is my thunderbolt nightmare. Dead drive in a Thunderbolt Promise Pegasus unit, web ticket filed for registered hardware. Legacy. That’s the word they used. Where’s Marshall McLuhan when you need a proper redux of the shit storm you’re in? Thunderbolt 3 uses USB-C and everything is possible. Can’t wait to step into that confusing identity crisis. OK, back to the present day when I stared at the red blinking drive, a replacement drive from not long ago dead again, sitting in the last row of a now legacy Pegasus R6 unit. RAID 5, the most dangerous kind, this is what stood between me and uncertainty. The worst kind of RAID. Well, not as bad RAID 0. Raid nothing. Raid 5 is one bad drive away from a bad day. Backups? Hmm, I got those, I got plenty of those, but I don’t want to be tested today. No, not today. Not this bloody day.
I open the Pegasus utility and the GUI wants an update. Hmm, that’s not in autopkg, I think. Why is out of date? Munki let me down. I start to drift, to side shift into adding newer better recipes to autopkg, to tweaking my Munki repo, to what sessions would be awesome at the next MacDevOps:YVR conference. Gee whiz, I love open source, and everyone in the Mac Admins community…. Snap out of! I slap myself in the face. I was hallucinating. Stay on task. I update the Pegasus utility. I stare at the critical reports from one of the three R6 units attached to this Mac Mini server. Did I say server? But it’s so small, so little. It works. It’s magical, kinda neat. Until you stare too close at the back. The Thunderbolt cables go from the Mac Mini to the first Pegasus unit to the SANlink fibre channel adapter to the LTO 6 tape library to the next Pegasus utility to the second SANlink adapter to a third and final Pegasus RAID unit. What’s is going on? Where does this cable go? Let me just follow it to the next jumping off point. My brain slows, the lack of oxygen in this cold machine room start to affect my thinking. I lose my way.
I download the report for the Pegasus unit. I had to unlock a pretty neat lock icon and click on the save report. I upload it to the web support and add it to the ticket. Tech support gets backs to me in a day and said all is good, and to carry on. I can’t. The drive is dead. What are they not seeing? It’s right in front of me. I download the report again. Again the same response. Fine. It’s time to stop messing around and pop open Terminal. Loading up promiseutil I check out the options and switches and get into an argument with myself about the currently valid optionals of letters and numbers that are required. I check my notes, online knowledge base, and try again. It’s broken. It doesn’t work. Stumbling around the command line typing imprecisely incorrect statements gets nowhere fast. I realize that there’s no way for the cli utility to properly change its focus to the broken unit with the busted drive. Both the GUI and the binary are stuck on the one R6 unit and won’t see what’s in front of my face.
I call tech support. This is humiliating. This was supposed to be easy. Drive dead, drive reported, drive ordered, drive replaced, then no one the wiser. Data saved, not dead. Backups not tested. Not today. No, not today. Tech support treats me like the imaginary newbie IT people sometimes treat everyone with. He repeats his instructions to me. He is polite. Download the report. I can’t. It won’t work. Unplug the unit. Plug it into something else. I can’t. The cables. The Thunderbolt cables are everywhere. It’s magical, and daisy-chained, and stuck. “Can I remote in and see?” he asks, hoping to resolve this quickly. Sorry. That’s impossible. Even if I thought it was a good idea. I remind him that I have a dead drive. That’s why I called. I want to get a replacement drive. “Sorry sir that legacy unit is not under support most likely,” I know that. I realize that now. That I wasted my time. It happens sometimes. The truth is staring at you. You need a mirror to see. “You need to order compatible drive from the compatibility list.” I am a well spring of emotions. I thank him. I am nice. He was polite. But now I know what I need to do. Oh wait, what? Order a drive now! Order two.
McLuhan never had a chance to evaluate Thunderbolt storage technology but the insane genius and simplicity of Thunderbolt reduced expensive enterprise fibre channel storage to the dust bin. Magical SAN for video editing with a Mac Mini and Thunderbolt RAIDs. Cheap enough to buy with a departmental credit card, fewer meetings to attend, more films to shoot and edit. Backup, archive, repeat. McLuhan would have no doubt reminded me that the tetrad of technology would have flipped Thunderbolt on its head, Fibre channel never went into a dust bin, but was firmly relegated to well cooled storage room, and long ago legacy drives in the enterprise units are humming a long while the cursing wind and emotions swell over the Thunderbolt mountain. Fibre channel just became cool again. Retro smart.
Announced late in 2015 the Archiware P5 Archive app is a revolution for editors who want to control the archive and restore process. No longer the job of the IT Admin, editors can select files or folders on their SAN volume (or anywhere) and send them to the tape archive.
The Archive app is a brilliantly simple app that allows the right-click services action in OS X, or in another words a it’s a GUI app that presents a contextual menu that knows to how to the talk to your P5 Archive server. When the files are safely on tape the original files on the filesystems are replaced with stub files that can be used to start the restore process.
Requirements: Archiware P5 server with the Archive module setup with an Archive plan. Add to that the P5 Archive App which is installed on the clients.
Note: At the moment all archiving goes over the LAN by default, so if you have a fast SAN then you set up the P5 Archive app client settings as “localhost” instead of their actual client name. That means that when it goes to archive the file, the server knows that the files exist on the SAN at a known path (which is the same on the client and the server).
And now for some detailed steps and screenshots.
Archiving completed projects
Choose the completed project folder and right-click. Select “Archive to P5”.
Note 1: If you want to restore files choose the folder that was archived and right-click. Choose “Restore from P5”.
Note 2: Restoring individual files that have been archived is possible by double-clicking the files with the “.p5a” extension, but it will be much faster to select an entire folder to restore than many individual files.
Note 3: For either archive or restore to work the P5 Archive app needs to be installed.
Note 4: To avoid having a services sub menu keep the contextual-menu items to four.
2. Archiving app status
When you are archiving or restoring files the Archive app will show you the status of your request. It will also show you the status of other jobs running on the P5 server. This is to let you know why perhaps your archive or restore is taking a long time (it’s possibly waiting for access to the tape drive and it currently busy backing up or archiving something else).
The P5 Archive app offers you three operations “cancel job”, “list items” and “get report”. The last two are great when you want to examine a completed job, for example. If you want to find out what files were archived in the particular job choose “list items”.
3. Restoring files
Archived files will have either one of or both of, 1) a”.p5a” file extension and 2) a P5 Archive app icon.
Folders and FCP X project bundles (which are folders) do not get the “.p5a” extension, but FCP X projects have the the icon.
Note 1: Files can also be restored by the admin through the P5 web interface. They can be restored in place or to any other location that is required.
Note 2: On the P5 server jobs that are sent to archive or restored from tape show up as “cli job” with the tapes in use. Actual files or folders involved need to be noted from the P5 Archive app not the P5 web admin console. Otherwise checking the P5 web restore tab will files actually archived (that can be restored).
That’s enough for the quick overview of this great new app. One of the best things in 2015.

Big thanks to Ross at Ping Identity for organizing and Jamf for sponsoring the Mac Admin meetup on September 9, 2015.
We filled the tiny meeting room and we will have to expand to the larger conference room (or theatre) next time. It was a well attended meetup with much discussion of the earlier day’s Apple announcements, new OS X “El Capitan” and iOS 9 changes and how this affects management products like Casper which have had to move the binary because of the new SIP implementation in OS X.
The goal of my presentation was to give a quick overview of SAN technology as I’ve seen it change over the last 10 years: from Fibre Channel, to iSCSI to PCIe and Thunderbolt based. The last change to Thunderbolt based SANs is the most interesting for small video production workgroups or anyone that likes working on small scale shared projects but needs a decent bandwidth at an affordable price. Block level storage (SANs) is straight forward storage tech for users and applications to interact with without having to negotiate network protocols (AFP, SMB, or NFS). It’s never been quite that affordable until now.
Having built a lot of Fibre Channel based SANs for media and entertainment companies and post-production editors in corporate environments I know how awesome and fast and solid these SANs are. Lots of editors and clients can hit a large SAN and it won’t blink. Thirty or Sixty users is not unusual. But not everyone believes in fibre channel or the idea of pulling fibre cables. It is surprisingly a large stumbling block to building large SANs, “no, we don’t want fiber cables”. True, sometimes clients have objected to gigabit Ethernet too, but that’s another story.
I found that iSCSI, especially with the DDP units I’ve set up, has been a great alternative to fibre channel. Not fiber cables to pull. Just use the CAT6 cables already in place. Great Ethernet based SANs using 1 x or 2 x CAT6 cables per client, or even 10G. Works well. Very well indeed. It’s been great for smaller (and larger) clients who want a great Ethernet iSCSI SAN solution without needing fibre channel cables, switches, HBAs, Thunderbolt adapters, etc.
That’s why when I stumbled across the Accusys Thunderbolt storage I was kinda really excited. No fibre channel to Thunderbolt adapters. Just use Thunderbolt cables. Brilliant! Finally a solution for small workgroups. And there’s so many video groups sprouting out of every corporate office, or boutique VFX or post-production shops that have been struggling with small NAS solutions that were not meant for video production. Now you can get that SAN that you’ve wanted, you can really get that block-level storage at an affordable price. Instead of working locally and copying raw footage and finished products back and forth across slow network links they can work in a small video group with high speed storage. Sa-weet. (Can you tell I’m excited?).
I’ll include the presentation PDF here as a link if anyone is interested. I’ve added a link at the end from Accusys on how to build an Xsan with the A16T2-Share. Yes, Xsan from Apple still exists and is bundled with the OS for free. Building a SAN is pretty easy and everyone can do it. Don’t forget your backups though.
Lastly, anyone interested in attending any meetings for the upcoming MacDevOps:YVR (June 16-17, 2016) drop me a note. I added the email in the presentation document.
I saw something wonderful and new at NAB today. The Accusys ExaSAN Thunderbolt shared storage shouldn’t exist but there it is. With 16 x 4TB drives and 4 Thunderbolt ports out the back to connect 4 clients (one of which could be a Mac mini acting as a Xsan 4 controller). That leaves 3 spots for Mac clients for a small editing SAN or post-production workflow. Prices to be revealed soon, I hope. Very interesting for small setups.
