One point I missed out earlier is that ocfs2 should not be viewed as
an Oracle only product. When the fs was pushed into the mainline kernel,
it was because we wanted it to become a community project. Like Linux
itself.
Until some time ago, we would credit non-oracle people who contributed
patches
Unsure what the confusion is. The answer was correct. fscat can read
certain unmounted fs. The list is mentioned on the home page. ext2, ext3,
ocfs and ocfs2. It does not write to these file systems when they are
unmounted. It can write to any mounted file system.

Ask Novell whether you should upgrade or reinstall the OS. It is
afterall a large jump. From sles9 sp3 to sles10 sp2.
But when you do the change, install the latest sles10 sp2 kernel.

No, this is not configurable. We have to fence else the processes will hang.
From your description it appears it is rebooting because the hb ios are not
completing within the timeout. What is your current setting?
O2CB_HEARTBEAT_THRESHOLD in /etc/sysconfig/o2cb.

While a node can only be in one cluster, it can be in many
different dlm domains (or lock name spaces), each of which
can have a different collection of nodes. But in the end,
the sum total of all nodes in all domains will still part

You are using ocfs2 atop lvm - a non-cluster-aware volume manager.
A lot of things can go wrong in this combination. Quite a few have
been reported on this forum.
debugfs.ocfs2 has commands dump and rdump that allows users to
read the files directly off the disk. Use it to recover your data.

Actually, it is not complex.
o2cb timeouts: If not using multipathing/netbonding, leave the timeouts
as it. If using multipathing, double the disk hearbeat to 120 secs.

Do on both nodes:

It should be the same.

Sure. One can use ocfs2 to host almost anything. The one exception
is the crs_home. crs_home needs to be on a local volume.

ocfs2 is a shared disk cluster file system. All nodes need to have
access to the disk. Typical technologies involved are fiber channel
and iscsi. If you are in a virtual environment, then you could present
a local device as shared to multiple guests.

Do you have a separate network path for drbd traffic? If you do
not, then you are probably overloading the network. In this case,
I believe drbd is unable to replicate the ios fast enough and thus

The nodes are not frozen. The processes that are attempting to talk
to the "disconnected" node are waiting for that node to reply, failing

If that node simply died, the other nodes would have deemed the node
dead after 60 secs,

Explain "repository built by OCFS2 1.4.x"? What is this repository?
OCFS2, the file system, is architecture neutral. Meaning, it works
across 32-bit, 64-bit, little endian and big endian boxes. One can
mount an ocfs2 volume concurrently on x86, x86_64, ia64 and ppc64
nodes. They all have to be Lin
to their repository. Having
said that, a 64-bit system does not necessarily imply 64-bit apps.
The apps itself could be 32-bit.

Setup netconsole to trap the logs. Once you have it then file a
bugzilla and attach the logs of all 5 nodes.

The fix was for the oops you saw.
The hang is a different issue. We have no info on that.
For that, if you would like to diagnose the problem, read up the dlm notes
in the 1.4 user's guide. It explains a debugging process vis-a-vis hangs.
If the issue is dlm related, then we would like to have t

Please do remember to file a bugzilla. Once it is fixed, add the git
commit details to it.

This patch should be in ocfs2-1.4. It is not in ocfs2-1.2. Ignore the
kernel version. Both 1.2 and 1.4 work on el5.

Please file a bugzilla and attach the netconsole logs of all six nodes.
The messages provided indicate that that node saw the two nodes
become unresponsive. As to why they became unresponsive will be
known only after we see the netconsole logs of the two nodes.

"device busy" could be because you have a shell having that as the cwd.
Check:
ls -l /proc/[0-9]*/cwd
