I have to admit that fencing hasn't been enabled in this cluster, 90% of
jobs on these 2 nodes are working with other storage that is accessible
by NFS. So it wouldn't be okay to reboot a node due to any problems with
GFS2.

Oh, yes, I'm going to use a separate physical NICs for interaction with
that storage, but it hasn't been implemented yet.

Thank you.
