[Debian-ha-maintainers] Bug#585023: drbd8-utils: OCFS2 + mdadm checkarray reboots due to lost heartbeat in DRBD during writes

[caitlin]

Package: drbd8-utils
Version: 2:8.0.14-2+lenny1
Severity: important


identical mdadm array built on two hosts (DELL 2950)
Dual primary DRBD
resource filesystem OCFS2 mounted to both hosts.

During monthly cron checkarray run on 1st Sunday of every month, syslog reports loss of DRBD heartbeat. OCFS deems the node to have left the pool, then reboots the machine to try and rejoin the pool (fencing).
System works as expected all other times.
