Why does a pve ceph-host crash causes the monitor to be dysfunctional?

[budy]

I am quite curious… I experienced some HW issues (well, presumeably) on one of my Ceph nodes in my 3-node Ceph cluster. Everytime I rebootet the host, which then had been hung for some length of time, the Ceph mon on this host would be dysfunctional and I needed to re-setup the monitor. Is this behaviour to be expected?

Thanks,

It sounds like an underlying issue with the storage. Check why the host itself hangs.

Yeah… obviously, but… I still wonder what causes the issue with the monitor. root is on ZFS and the volume comes back clean and I don't see a reason why the monitor shouldn't get back up and running.
