[Linux-cluster] Oops


I wasn't sure whether to send this to LKML or here, but DLM seems
involved.  Please let me know if I'd better repost it to somewhere

It's a vanilla 2.6.21 kernel patched by cluster-2.00.00 (with the
three extra export for GFS1).  Config attached.  The machine froze
during the morning updatedb cronjob, which performed a recursive find
into the shared GFS filesystem.  Two other nodes doing the same at the
same time are still up.

I experienced a similar hang with cluster-1 not long ago, though that
didn't lock up the whole machine, but the cluster software only.

Please ask back if I didn't provide all information necessary.
clvm: 2.02.26
libdevmapper: 1.02.19
openais: 0.80.2
otherwise stock Debian Etch system.
