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
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
And whats with GFS kernel module depends on GFS2 module as seen in:
root at srv02:/storage# modinfo gfs
author: Red Hat, Inc.
description: Global File System <CVS>
vermagic: 2.6.24-19-server SMP mod_unload 686
root at srv02:/storage#
Does this mean that GFS is using the locking infrastructure of GFS2
Or is Ubuntu 8.04 somehow inconsistent regarding RHCS?
