[PVE-User] PVECluster Issue

Hi everyone,

I have an issue with a intel modular server with 5 nodes. Whenever the nodes run a backup, some of them fail and often the VM’s become locked. These VM’s are all QEMU based virtual servers and not openvz as they are Windows servers.

Often everyday, I need to restart the cluster after something like this appears in the backup logs by going to one of the nodes that is red and restarting the PVECluster, which I believe is the correct way to do this, so please correct my if I’m wrong.

The backups all go to an NFS share mounted on on a private network over gig ethernet. 
Any ideas as to why this is happening? The backups are all staggered from the hosts to back up to the share

Thanks for any insight.
