[Ocfs2-users] heartbeat write timeout

[Stephan A. Rickauer]

Dear list,

I am evaluating ocfs2 in a test environment, that currently runs a
"cluster" in a one node mode (AMD Opteron, 2GB RAM, RH AS4 (CentOS 4.3),
2.6.9-34.EL) connected to an iSCSI storage device. While doing load
tests with 'bonnie++' to test the performance of the storage device
together with the file system I experience regular kernel panics related
to ocfs2 (1.2.0 RPMs).

Here is the message I get (I did not want to file a bug yet, maybe it's
just me missing something). sdb1 is the iscsi device:

---snip---
(3,0):o2hb_write_timeout: 164 ERROR: Heartbeat write timeout to device
sdb1 after 12000 milliseconds
(3,0):02hb_stop_all_regions: 1727 ERROR: stopping heartbeat on all
active regions
Kernel panic - not syncing: ocfs2 is very sorry to be fencing this
system by panicing
---snip---

I am tempted to rule out iscsi storage device related problems, but this
is not 100% sure, though tests with GFS and ext3 did not reveal
comparable problems.

On the bug page I spotted ID565 which seems to fit my szenario, but the
status of the bug is unclear to me (references to version 0.99 are
given): http://oss.oracle.com/bugzilla/show_bug.cgi?id=565

Any help / comments etc. are appreciated.
Thanks.
