Hi Theophanis,

That's not enough information to tell what's going on.
It would probably be more helpful if I could get the full call trace,
and the last several lines of output from fsck.gfs2 -vv <device>.

It would even be better if you built gfs2.fsck from the latest source
tree, changed the Makefile to use "-g" rather than "-O2", compiled it,
and then ran it from gdb.  Then if/when it segfaults, you can do "bt"
to get a better backtrace.

Also, be aware that GFS2 is not ready for production in RHEL5.1.
