I'm having issues troubleshooting why backups wont work on 1 node in a cluster. Backups work on all the other nodes just fine, but this particular node keeps doing a "permission denied" when doing a backup of a container. What is even weirder, is that some other LXC and KVM guests can backup just fine on the same node!?
After doing some googling, i tried setting chmod 755 on the nfs folder(s) and that did nothing to fix my problem.
Here is the complete error when trying to backup this LXC
Any suggestions on how to make this thing work? Not sure why other containers and VM's can backup, while others can't on this particular node.
