[SOLVED] Unable to boot vms


New Member
Jan 14, 2023
Hi all

I am unable to boot most of my VMs.
Two are running (i.e. I was able to boot them).
Ceph seems to work fine.

When I try to start a VM I don't get any error message. Any ideas why?

Also, what is the expected output of the command `pmxcfs`
I am getting '[main] crit: unable to acquire pmxcfs lock: Resource temporarily unavailable'. But as two VMs are working, I am puzzled...

I recently restarted most services and hosts, because of the pmxcfs status:

root@pve1:~# qm start 101
Requesting HA start for VM 101

turns out restoring from backup does the trick.
Maybe the data on ceph got corrupted when I rebooted/updated the nodes yesterday. Strange that (a) two VMs were working all along and (b) I did not see any error message when trying to start the other VMs
