"The selected network backup disk does not support the required capabilities."

I am seeing the above message when trying to remotely connect to a RAID5 ThunderBay 4 mini APFS volume, shared from Sharing prefs as a Time Machine volume with SoftRaid 6.2 on an Intel Mac mini. I have existing network time machine backups on this volume, so I'm pretty sure this must have been working in a prior SoftRaid version (and it's APFS so it must have been SoftRaid 6?)

The error I see in the console logs says:

com.apple.prefs.backup.remoteservice: (TimeMachine) [com.apple.TimeMachine:General] '/Volumes/ThunderBay' does not support SMB FullFSync

Is there some setting I can change on the volume that would make it support SMB FullFSync? I tried disabling write caching just in case but that didn't change anything.

If I create an APFS volume on an external USB drive and share it from the Mac mini the same way, I'm able to connect to it and use it for Time Machine remotely, so this doesn't appear to be an APFS issue.

I've even gone so far as installing Big Sur 11.6.1 on a separate volume, installed SoftRaid 6.2, exported the RAID volume for Time Machine and it still doesn't work, so this doesn't seem to be a Monterey regression...

This is way beyond my knowledge base. Maybe another reader can respond?

 

Maybe try replicating it with a USB drive with a non RAID SoftRAID volume on it. its possible this is a Time Machine/macOS bug, as a SoftRAID volume should behave identically with standard volumes.

A non-RAID SoftRAID APFS volume on a USB drive does not reproduce the issue. I'm going to try copying the data off the RAID5, re-initialize and re-create the RAID and see if it still happens...

I deleted and recreated the APFS RAID5 volume and now it works?

@mgwatson

these things can be so frustrating. Perhaps some ownerships were not correct somewhere.

 

Glad it is working now!
