Thanks Steve for the reply . 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.
Thanks in Advance
Zaman
