To mount without heartbeat, you have to make it a local mount. Maybe mount.ocfs2 should error out if user specifies heartbeat=...
To make it mount locally: umount on all nodes tunefs.ocfs2 --fs-features=local /dev/mapper/.... mount /dev/mapper/... /mnt/path To revert: umount tunefs.ocfs2 --fs-features=nolocal /dev/mapper/... On 09/14/2011 12:23 PM, Ulf Zimmermann wrote:
Sunil, I was trying to see what the speed difference would be if I mount a volume with no heartbeat (for copy purpose): dbtest01 root /home/ulf # mount -o datavolume,nointr,heartbeat=none /dev/mapper/350002ac001380dab /export/coptest/ dbtest01 root /home/ulf # mount /dev/mapper/350002ac001380dab on /export/coptest type ocfs2 (rw,_netdev,datavolume,nointr,heartbeat=none,heartbeat=local) This was with o2cb running, is this right?

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.
