Re: [Linux-cluster] RHEL Cluster node fencing and cluster



Title: Re: RHEL Cluster node fencing and cluster

Hi

Gfs file system I have created is not being used for services running on tis cluster. I was planning to use it for a database but I was getting into stale cluster problem as soon as file system was created. After changing to gfs instead of gfs2 everything is fine.

Thanks
Anoop

in your cluster.conf

fstype="ext3"

it should be fstype="gfs" or gfs2
