Mounting a GFS filesystem on two or more nodes concurrently
requires that you have a lock manager in place. The cluster suite
provides DLM for this, which absolutely requires an operational cluster. (You can mount GFS on a single node with no cluster, but that's not
a very interesting way to use GFS.) From:
linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On
Behalf Of Fagnon Raymond I have a hypothetical question. Will GFS work without the
cluster software active? Here is what I would like to do. I have a two node nfs cluster. Currently the cluster is set
up as active standby. What I propose is to shutdown the cluster software leaving
GFS in place. Have both nodes NFS out /datadir. Put the virtual ip on an f5
load balancer and have NFS load balanced between the two nodes. This will
allow me to leverage both servers instead of leaving one idle. Is this possible to accomplish. My understanding is that gfs
is used to allow two nodes access to one file system whether they are running
cluster software or not. |
