Copied file is 0 bytes!

About a month ago we received a comment from a client.  They had a user who grabbed some files from their Xsan volume, dragged them to their Mac’s Desktop and ended up with 0 byte files!  The file on the san opened fine.  We found copying it with cp or rsync resulted in normal files.  The problem was not permissions (POSIX or ACLs) or extended...

Latest Apple updates fixes Xsan mounting issue

The latest updates from Apple, January 22, 2024, (we’ve tested 14.3 and 13.6.4) have fixed the Xsan mounting regression from the .2 versions. [Edit: 12.7.3 has been confirmed to work by matx on Slack.  Thanks Mat!] The simplest confirmation is that your volumes should mount properly with xsanctl either automatically or manually.  We can confirm by checking the latest /Library/Logs/Xsan/debug/mount-debug.nnn file (where nnn is some number)....

Xsan automount failures in macOS 14.2, 13.6.2/3, and 12.7.2

Several Xsan administrators have been reporting problems on clients that have been upgraded to any of the latest point releases from Apple.  The clients fail to mount their Xsan volumes and even manually mounting with xsanctl mount VolumeName fails.  There has been much discussion and a work around found on MacAdmin Slack in the #Xsan channel, so join us over there. The problem can be...

Xsan Ventura & Sonoma upgrade failures and a workaround using profile “Magic”

We have recently been upgrading our clients’ Xsans from macOS Monterey to macOS Ventura.  We had been holding off since, in our testing over the last year, we have never had a successful in-place upgrade.  When trying an in-place upgrade on an MDC, the install progresses until the first restart.  At that point, the Mac boots to recovery with an error message: “Your computer started...

Moving a user’s home or CloudStorage wants a lot of space

Why would we do this We have several customers that use various cloud sync/storage options as another location for archived data.  Once the projects are complete and we mark them read-only on the Xsan, they can be written to tape and sent to “the cloud” for further redundancy.  This means we are almost constantly sending data up to these providers.   In macOS Monterey (and...

Monitoring and killing smbd

We have several clients using macOS to share data from their Xsans. There have been occasional instances where the smbd process spins up to over 100% and seems to get hung up. Connected users report slow file browsing or not able to navigate to new folders. New connections timeout before being prompted for authentication.We have found that killing the smbd process resolves the issue and...

Moving to M1/arm native rsync

We are in the process of replacing Intel Mac minis with M1 Mac minis in our customers’ server rooms.  For the MDCs we are using migration assistant and rebuilding the Open Directory master first, then migrating the BMDC and cleaning up the Xsan configuration and re-joining the Xsan.  For other systems (file servers, sync servers, etc) one of main tools for data movement is rsync...

Creating an html file list of an archive

We recommend our clients use a Production -> Nearline -> Archive workflow.  Production data is synced to Nearline (full copy nightly, syncs every hour).  Then when projects are complete, data is sent to duplicate tapes and cloud storage.  While people can view and search archives in the cloud or the Archiware P5 web interface, often they like to navigate in the file system they are...

Converting local accounts to mobile accounts

When working with an Xsan volume with Access Control Lists (ACLs) enabled, it is critical that users log into their Macs with the accounts that are in the relevant groups.  We recently helped a customer migrate  several computers from local accounts to mobile accounts while retaining the user’s home folder. We are starting with a Mac with a local administrator account and another local account...

Another ARD offline issue

We have a lot of headless Mac Minis in server racks running Xsans and related services.  So we use Apple Remote Desktop (ARD) quite a bit to connect and work on them.  For most of their history, a Mac Mini without a monitor was limited to low desktop resolutions (like 1280×1024 or even 1024×768), could lose any graphics acceleration from the Quartz Core Graphics framework,...

Apple Remote Desktop constant resizing

We use Apple Remote Desktop (ARD) for many things from working on headless servers to remote users working on Xsan connected systems while working from home.  Occasionally, we run into a problem when connecting to a remove system via ARD where the window wildly resizes itself and eventually errors out. In some cases the cause seems to be a user changing the resolution of the...

No login window icon if your UID is too large

We ran into an interesting problem on some of our Xsan connected systems.  We created mobile accounts, but some of them wouldn’t show up at the Mac’s Login Window. These Macs are bound to an LDAP server and the user’s UniqueID (UID) comes from the LDAP server.  The UIDs are assigned based on user type, so while employees are small numbers, contractors have ended up...
