[Linux-cluster] GFS: assertion "x <= length" failed

[Uli Schroeder]

Hi everyone,

I encounter the following problem with GFS unter RHEL4. Anyone familiar with
this one.

Apr 28 14:24:26 tstserver kernel: GFS: fsid=clmdb1:gfs05_0.1: fatal:
assertion "x <= length" failed
Apr 28 14:24:26 tstserver kernel: GFS: fsid=clmdb1:gfs05_0.1:   function =
blkalloc_internal
Apr 28 14:24:26 tstserver kernel: GFS: fsid=clmdb1:gfs05_0.1:   file =
/usr/src/build/574066-ia64/BUILD/gfs-kernel-2.6.9-35/src/gfs/rgrp.c, line =
1450
Apr 28 14:24:26 tstserver kernel: GFS: fsid=clmdb1:gfs05_0.1:   time =
1146227066
Apr 28 14:24:26 tstserver kernel: GFS: fsid=clmdb1:gfs05_0.1: about to
withdraw from the cluster
Apr 28 14:24:26 tstserver kernel: GFS: fsid=clmdb1:gfs05_0.1: waiting for
outstanding I/O

What can I do against it? Anytime the error occurs all I get when I try to
access a directory on that volume is an "Input/Output error". The failure
occurs regularly and can only be resolved by booting the system.

Interestingly the error doesn't apply to all GFS volumes on a server. One
volume regularly fails while the other is up and running all the time. There
was no difference in setting them up.

Anyway the could be observed on different servers.

Best regards,
Uli
