[Linux-cluster] GFS: assertion failure in add_to_queue

[Ferenc Wagner]

Hi,

I'm using a 1-node GFS1 "cluster" with DLM locking and sporadically
(say once a week) get the following in the kernel logs (Linux 2.6.23):

GFS: fsid=noc:cricket.0: warning: assertion "(tmp_gh->gh_flags & GL_LOCAL_EXCL) || !(gh->gh_flags & GL_LOCAL_EXCL)" failed
GFS: fsid=noc:cricket.0:   function = add_to_queue
GFS: fsid=noc:cricket.0:   file = /home/wferi/cluster/cluster-2.01.00/gfs-kernel/src/gfs/glock.c, line = 1420
GFS: fsid=noc:cricket.0:   time = 1197666253

The filesystem is under constant reading/writing and seems to operate
without any application-visible errors (or at least I coultn't find
error messages).

Maybe it's no big deal, but something is not quite right.
But what?  Anybody has an idea?
