Hi,
Creating a sparce bundle on a mounted SMB share from macOS Ventura 13.4 fails with a 512 error. This seems to be the root cause of the failure of setting up a new Time Machine backup as details in this thread.
In trying to track down the issue, I was able to verify that creating a sparsebundle (a sort of macOS dynamicly allocated file) is not working when the file creation is attemptted on a TrueNAS Core SMB share.
Attempting to create a sparsebundle image from Disk Utility on SMB share location leads to this error:
Creating disk image “Untitled.sparsebundle”…
Operation failed with status 512: error 512
Operation failed…
This matches the error shown in the Time Machine errors, but I think it's unrelated to Time Machine. I have other macOS devices that already have Time Machine set up using TrueNAS Core SMB share and they continue to work. So, it seems like it's the initial sparsebundle creation that is failing.
It fails even on machines where Time Machine is already configured and working (i.e. where a sparsebundle file already exists).
The following command can be used to create a sparebundle image from the command line with details debug output:
The point it fails seems to be here:
@anodos , I know you usually deal with SMB issues, so hopefully you've got some idea of what's causing the issue.
