<![CDATA[XO Backup Error: VDI_IN_USE(OpaqueRef:.., destroy)]]>Hi there.

Given is a community edition XO on commit 3500d.

Since June 6th one out of seven VMs is no longer backing up.

It is always the same VM which is failing.

The remote is working (six VMs back up without issue).

It seems XO has trouble cleaning up the backup directory:

Here is the full backup log:

Maybe this is linked to the thread by @andrew :

https://xcp-ng.org/forum/topic/12249/xo-error-warning-clean-vm-directory.-unhandled-error-while-checking-alias./37

I upgraded today to commit 3500d, rebooted the XO VM and retried the backup. Still failing.

Thanks for the assistance.

Marc

The VM could be backed up successfully with the same warning about the "disk parent":

I am using "smart mode" for backup jobs. The standalone job went through with and without "smart mode".

Removing the tag from the VM in question and adding it again did not help. I have also deleted the snapshot linked to the backup job and retried, with no change in behavior.

The VM is shutdown and I only turn it on when I need to. During backup it is usually not running.

Thanks again.

Marc
