[Linux-cluster] Kernel oops when GFS2 used as localfs

[Sridhar Ramaswamy (srramasw)]

I hit various kernel oops while running some metadata intensive test on
GFS2 filesystem. This volume is intended to be used as local fileystem.
So it was created using lock_nolock. Also no cman, fence and any such
things are running in the system.
 
RHEL4 distro
Linux kernel 2.6.20.1 (from kernel.org)
cluster-2.00.00 (from tarball)
 
David.T earlier suggested to move to newer kernel (2.6.21-rc), which I'm
planning to do. Meanwhile I want to poll the alias on such issues in
GFS2. Ofcourse I'm all ears on any other ideas to resolve this!
 
thanks,
Sridhar
