Backups for all machines show Input/output error (os error 5)

[harmonyp]

I am getting the following error code for all virtual machines. Rebooting the PBS node temporarily fixes this.

VM 231 qmp command 'backup' failed - backup connect failed: command error: unable to read "/mnt/storage2/PBS/Alpha/vm/231/owner" - Input/output error (os error 5)

What are some of the common causes of this?

Any hints in the syslog on the BPS server?

Yes a lot of errors but not exactly sure when it began https://pastebin.com/BUg1mCTL

Looks like a hardware problem with the disk controller (or maybe the disk itself).

Which part? So I can google and hopefully find some tests to run.
