To mount without heartbeat, you have to make it a local mount.<br>
Maybe mount.ocfs2 should error out if user specifies heartbeat=...<br>
<br>
To make it mount locally:<br>
umount on all nodes<br>
tunefs.ocfs2 --fs-features=local /dev/mapper/....<br>
mount /dev/mapper/... /mnt/path<br>
<br>
To revert:<br>
umount<br>
tunefs.ocfs2 --fs-features=nolocal /dev/mapper/...<br>

Subject: Re: [Ocfs2-users] mount type heartbeat=local<br>
<br>
That mount option is appended by mount.ocfs2. It tells
users<br>
the heartbeat mode. "none" means non-clustered. "local"
means<br>
the heartbeat region is on the mounted volume. This is
the default<br>
mode. In 1.8 we have "global" which means the heartbeat
region<br>
has been configured on 1+ devices. local and global are
only<br>
pertinent in the o2cb stack. If you are using pacemaker,
you will<br>
see cluster_stack=pcmk and not heartbeat=.<br>
<br>
There is no heartbeat=cluster.<br>
