My confusion here is If I just run the cluster software ( cman etc ) without creating a cluster , will I be able to configure and run GFS2. Also , is it possible to write to a GFS file system from many servers at the same time ? > > Will be great if somebody can clarify by doubts. > > > Thanks in Advance > Zaman > > > If you want to use GFS2 without a cluster, then you'll only be able to > use it from a single node (just like if you were using ext3 for > example).

As you said setting up a cluster is needed to use GFS2 with multiple nodes, does that mean that I need to create cluster.conf or running cluster services (cman etc) should be fine for setting up GFS2. Not sure whether cman will run without creating cluster.conf Assuming that I need to setup cluster.conf in order to use GFS2 , that means if there are two nodes in the cluster with GFS2 as file system resource , GFS2 will be mounted on only one host based on failover domain policy . But our requirement is like that GFS2 should be mounted on both servers at the same time . Based on my little understanding of GFS , looks to me that I will not be able to achieve this using GFS2 or there are some way to achieve this ? Please clarify on this.
