Ok, using a disk attached via fibre channel to a single machine via an
LSI hba I can create and mount a GFS file system using lock_nolock
without a pool. A start!

Console log:

GFS: fsid=(8,2).0: Joined cluster. Now mounting FS...
GFS: fsid=(8,2).0: jid=0: Trying to acquire journal lock...
GFS: fsid=(8,2).0: jid=0: Looking at journal...
GFS: fsid=(8,2).0: jid=0: Done

I then tried to do lock_nolock on a pool device, and that worked as
well:

GFS: fsid=hopkins:gfs01.0: Joined cluster. Now mounting FS...
GFS: fsid=hopkins:gfs01.0: jid=0: Trying to acquire journal lock...
GFS: fsid=hopkins:gfs01.0: jid=0: Looking at journal...
GFS: fsid=hopkins:gfs01.0: jid=0: Done

So it appears to be specifically related to lock_gulm.

Anything else I should try?

I really appreciate all your help in debugging this!

Thanks,

Micah
