[Linux-cluster] GFS vs. GFS2: system-config-cluster, locking ...



Hello,

i'm playing with RHCS which is delivered with ubuntu 8.04 and i tried to
use GFS2. But i saw that using system-config-cluster it is not possible
to configure a GFS2 resource for use with a service. Sure i can change
the fstype manually in cluster.conf, but i think as GFS2 is still
considered experimental it should not be considered for a production
machine.

When is GFS2 planned to be used in production scenarios?

As i read long ago and if i remember correct for GFS there was a lock
server required (gulm, or similar...)

Is this still true? How do i correctly install GFS? Is GFS able to use
lock_dlm?

And whats with GFS kernel module depends on GFS2 module as seen in:

root srv02:/storage# modinfo gfs
filename:       /lib/modules/2.6.24-19-server/ubuntu/fs/gfs/gfs.ko
license:        GPL
author:         Red Hat, Inc.
description:    Global File System <CVS>
srcversion:     4695C79080CC395FA4E74E5
depends:        gfs2
vermagic:       2.6.24-19-server SMP mod_unload 686 
root srv02:/storage#

Does this mean that GFS is using the locking infrastructure of GFS2
already?

Or is Ubuntu 8.04 somehow inconsistent regarding RHCS?

Chris
