I’ve got a 3 node cluster using NFS for the datastore - running 6.2 and running a handful of VM’s
Everything was fine then there was some power issues and I’ve now got 3 VM’s on one host that wont boot up - it appears disk.0 doesn’t exist on disk anymore - is there any way to recover from this?
The VM disks shouldn’t disappear in events like that. OpenNebula should perform some sort of Storage action in order for that to happen. Since you are using NFS, maybe the mount share is not properly mounted on the host, thus the disk being not visible.
