RHN was okay with that configuration and we have been running it this way on GFS and GFS2 for 5-years without issue.<BR><BR><BR>-----Original Message-----<BR>From: <A href="mailto:linux-cluster-bounces@redhat.com" ymailto="mailto:linux-cluster-bounces@redhat.com">linux-cluster-bounces@redhat.com</A> [mailto:<A href="mailto:linux-cluster-bounces@redhat.com" ymailto="mailto:linux-cluster-bounces@redhat.com">linux-cluster-bounces@redhat.com</A>] On Behalf Of Bob Peterson<BR>Sent: Monday, February 14, 2011 8:37 AM<BR>To: linux clustering<BR>Subject: Re: [Linux-cluster] want to use GFS2<BR><BR>----- Original Message -----<BR>| Hi,<BR>| <BR>| You need to setup a simple cluster and a proper fencing mechanism .
