[Linux-cluster] Fatal: filesystem consistency error

[Kadlecsik Jozsi]

Hi,

Today one of our machines reported the following:

Nov 26 11:44:08 lxserv1 kernel: GFS: fsid=kfki:home.4: fatal: filesystem
consistency error
Nov 26 11:44:08 lxserv1 kernel: GFS: fsid=kfki:home.4:   inode =
407901/407901
Nov 26 11:44:08 lxserv1 kernel: GFS: fsid=kfki:home.4:   function =
gfs_change_nlink
Nov 26 11:44:08 lxserv1 kernel: GFS: fsid=kfki:home.4:   file =
/services/src/packages/cluster-2.01.00/gfs-kernel/src/gfs/inode.c, line =
844
Nov 26 11:44:08 lxserv1 kernel: GFS: fsid=kfki:home.4:   time = 1196073848
Nov 26 11:44:08 lxserv1 kernel: GFS: fsid=kfki:home.4: about to withdraw
from the cluster
Nov 26 11:44:08 lxserv1 kernel: GFS: fsid=kfki:home.4: telling LM to
withdraw

What can be the problem and what could result it? Should we run gfs_fsck?

A side question: is there a way to run a custom script when one node 
withdraw itself from the cluster?

Best regards,
Jozsef
