[PVE-User] Cluster panic! - NFS mount fails

[Laurent Dumont]

Hi gents,

I had a small issue this afternoon where my 3 node cluster failed since 
my sharing NFS server decided it had enough with life. The first symptom 
was snmp failing on all three Proxmox hosts (which really stumped me for 
a bit) then all 3 nodes went offline in the web interface. The really 
weird part is that quorum was still good and "pvecm status" and "pvecm 
nodes" outputs seemed to look okay.

Can I really just attribute this entire thing exploding to just my share 
disappearing? That's a pretty bug failure for something that has nothing 
to do with the hosts themselves. I would have rather seen the node kill 
any vm living on shared storage, warm me but continue on living.

Cheers.
