Backup of Linux VM with [nobak] disk failing health check (Solved)

[andyh]

I had an issue with the backing up of a linux VM that had a [nobak] disk associated with it. When attempting the Health Check, I would receive the following error

waitObjectState: timeout reached before OpaqueRef:7c60ab35-dba3-4c4a-887a-0f350a68c3b9 in expected state

Watching the state of the VM startup, I could see the OS would not load. I initially thought this was an issue with XO, but earlier I realised it was the host OS hanging.

This was due to the OS not being able to mount the disk from the health check, as it was not backed up due to [nobak].

Modifying the /etc/fstab in the host OS to include nofail resolved the health check failure. Eg.

UUID=a2c230fd-13e0-4453-9d56-1ab123bfad9e /Cache xfs     defaults,nofail        0       0

Hopefully this will help anybody experiencing similar issues.
