Hi
I still don't know what caused it, wether the failure of one node in gluster
that lost one SATA controller and was rebooted or some user activity, but
gluster became quite unusable. Even basic gluster commands like gluster volume
heal home0 info etc didn't work either hanging or giving operation failed
results. I finally managed to stop the volume after numerous attempts and
restarted gluster on all nodes. However I don't seem to be able to do anything
useful still. Most commands fail and the log shows:

I've googled and seen people hit with this at times, but never resolutions. Is
there some way to clear this lock? It's been in effect for well over an hour so
one of the googled results that claimed there's a generic lock timeout of 30
minutes seems not to be at work here.
Any help would be appreciated.
