Hi, when I mount ocfs2 file system, what the heartbeat=local option means? what is the difference between heartbeat=local and heartbeat=cluster (I know that is default)? Thanks.

That mount option is appended by mount.ocfs2. It tells users the heartbeat mode. "none" means non-clustered. "local" means the heartbeat region is on the mounted volume. This is the default mode. In 1.8 we have "global" which means the heartbeat region has been configured on 1+ devices. local and global are only pertinent in the o2cb stack. If you are using pacemaker, you will see cluster_stack=pcmk and not heartbeat=. There is no heartbeat=cluster.

but this is what I saw in the guide
OCFS2 - A Cluster File System For Linux Mount Type
Valid types are cluster and local, with the former also being the default.
Specify
localif you intend to use the file system on one node only.
Thanks.

means

There is no heartbeat=cluster.
