As far as ocfs2 is concerned, bio_add_page() is failing. The one thing that
springs to mind is that o2hb sets bio-bi_sector to 512 bytes and not
the block size.

ocfs2 requires a shared disk. As in, all nodes must be able to concurrently
read/write to the device.

1. o2net talks tcp. It should be able to handle this.
2. If the cluster is active and the nodes are communicating,
the keepalive packet is rarely sent. It only sends the packet
if it does not hear from the other node for 5 secs.
3. Try the same with 1.2.3. (We made 2 important 1 line fixes.)
4.
Just create a one node cluster.
However, if you were to mount two mirrored volumes on the same node,
you will have problems as detailed in this thread:

When you added the new node using ocfs2console, did it show up in:

Before you can mount, you have to ensure all the nodes
in the cluster access the same device.
#echo stats | debugfs.ocfs2 -n /dev/sdX | grep UUID
should return the same uuid from all nodes.
Once all nodes can see the same device, the you can mount
it on all nodes. There are no passive node(s).
ocfs2-tools 1.2.2 will have the offline-extend feature.
Still in testing.

Check dmesg on both nodes.

Is it always the mount using node slot 1 that fails? If so, the jbd
superblock
may be corrupted for that slot.
Grow the journal by, say, 1MB. It will reinitialize the JBD superblock
for all
the slots. Either that or just reformat the device.
To see the size of the existing journal, do:

It's not a sysctl entry. It won't work that way.
Set the required value in /etc/sysconfig/o2cb
and restart the cluster. Do it on all nodes.

The hb failure is just the effect of the ios not completing within 12 secs.
The full oops trace gives the last 24 ops and their timings.
One solution is to double up the hb timeout. Set,

ocfs2-tools includes two init scripts, o2cb and ocfs2. Ensure the

the startup seq should network, o2cb and then ocfs2. The shutdown

In a 2 node setup, if node 0 or 1 crashes, the other node should survive.
The one issue encountered by many users was while shutting down node 0,
node 1 would fence it self. The latter was because of the sequencing of
service shutdowns. We added ocfs2-init script to handle shutdown
sequencing.
