You've probably hit the gfs_grow bug described in bz #434962 (436383)
and the gfs_fsck bug described in 440897 (440896).  My apologies if
you can't read them; permissions to individual bugzilla records are
out of my control.

The fixes are available in the recently released RHEL5.2, although
I don't know when they'll hit Centos.  The fixes are also available
in the latest cluster git tree if you want to compile/install them
from source code yourself.  Documentation for doing this can
be found at: http://sources.redhat.com/cluster/wiki/ClusterGit
