[pve-devel] Serious problems with the PVE Cluster

Serious problems with the PVE Cluster
----------------------------------------

@any developer that can help in the code:

I had problems with 2 of 5 PVE Hosts in a PVE cluster when the NFS Backup 
Server  was shutdown manually (without  that "KVM Live Backup" is running in 
the PVE Hosts),

The symptom was:
2 PVE Nodes were disconnected suddenly of PVE Cluster
The PVE GUI shows leds in red for the nodes without connection to PVE 
Cluster

To return to normal operation:
Only was necessary start the NFS Backup Server

I mean two stuff:
1- If "KVM Live Backup" is running in the PVE hosts while that  NFS Backup 
Server is shutdown suddenly, the problem would have been more serious.
2- The PVE Cluster not must depend of NFS Backup Server to run correctly, 
this situation is "VERY SERIOUS"

For these reasons i think it will be necessary to correct the code of PVE 
Cluster

Awaiting a answer, i say see you soon

Best regards
Cesar

mmm, good question....I don't known what happen when backup job is hanging 
because of unavailable storage...
