Hi,
Yes. Verification causes massive issues. I do not see another workaround
than ‘use ZFS and try to avoid running any verifications’..

Subject [PVE-User] Timeouts while creating backups on PBS
Hello
we have several clusters (~250 VMs) attached to one PBS and run daily backups.
Each day, there are random timeouts causing some backups to fail.
I've disabled the instant verification process to reduce IO-load on the PBS
during that time. The timeouts are gone since then.
Because we do want to have verified backups, we tried out scheduled verification
tasks. Then we have the problem, that it takes to long (>1d) to verify all ~250
new snapshots sequentially. 50 parallel verify jobs works well.
My current idea is to write a custom scheduler to make sure that there is a
custom amount of verify jobs simultaneously when no backups are running.
Is there a better way I don't see? If I may place a feature request: It would
be nice to be able to specify how many verify jobs can work simultaneously.
Thanks!
Sven
