[ovirt-users] Fwd: Issues Recovering NFS After Power Outage

[Chris Paquin]

Solved: Since my DNS server was down (as it runs in the RHEV environment) the hosts could not resolve the name of the NFS server.


Thread-21::ERROR::2016-02-03 18:25:35,654::storageServer::213::Storage.StorageServer.MountConnection::(connect) Mount failed: (32, ';mount.nfs: Failed to resolve server freenas.lab.localdomain: Name or service not known\n')


Adding static entry to resolv.conf on each hypervisor solved the issue. Next time I will mount via IP address instead.

Subject: [ovirt-users] Issues Recovering NFS After Power Outage

Please help. After a power outage all my nfs mounts (from two sources) are down. I have verified that they are mountable on my workstation.

I have tried to active my NFS Data Master, however the process fails with the message below.


Failed to Reconstruct Master Domain for Data Center Auburn_Datacenter.

Can someone assist in recovery?  I have seen posts mentioning that I need to verify that the rhev-m hosts can mount the storage, but whats rhev-m way to do that. I am assuming I am not just going to mount it via "mount".
