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.

As far as ocfs2 is concerned, you can use debugfs.ocfs2 to
check whether you are seeing the same "physical device" on
the two nodes.
# echo "stats" | debugfs.ocfs2 -n /dev/sdX
Compare the UUIDs.
# echo "ls -l /path" | debugfs.ocfs2 -n /dev/sdX

Well known problem with OCFSv2. One solution is to add 3-d node and use
interface bonding (be sure that interface convergeency time is less that
o2cb timeout).

BTW, you appear to be running with the default 12 sec timeout.
From what I've gathered, most users are appear to be using a higher
60 secs timeout. 12 secs does not leave much room for error.
We are thinking of increasing the default in the next drop.

I have increased my O2CB_HEARTBEAT_THRESHOLD to 61, but where is this message getting
"10 seconds" from?
Also this message is displayed because dbo2 was not able to check into the

Do it on both nodes. The UUID should be the same.

So we hope to pre-release 1.2.4 next week. The main patch looks
ready. We are adding one more small patch to it. Fingers crossed.
Extended Attrs is being targetted for 1.4... sometime next year.

Number of files/inodes in the entire fs is limited only by space.
However, on a per-directory basis, while the real limit is still very large,
the practical limit is in 10s of thousands.

You are on a very old release of OCFS2. The OCFS2 homepage and FAQ both
list a SLES9 kernel version newer than the one you are using.
But that may not be the reason for the error. My bet is that bdb is
attempting to create
a shared writeable mmap that ocfs2 1.2 does not support.
