...ut the interval seems irregular while the time that it hangs is quite similar. This behavior seems pretty much independent from the (IO) load of the nodes (as long as not really high). I tried a ps, grepping for D repeated every second on both nodes. When hanging, both show this: 1649 D< o2hb-02BC250CDB ? 3507 R+ ps - 1649 D< o2hb-02BC250CDB ? 3511 R+ ps - 1649 D< o2hb-02BC250CDB ? 3515 R+ ps - 1649 D< o2hb-02BC250CDB ? 3519 R+ ps - 1649 D< o2hb-02BC250CDB ? 3523 R+ ps - 1649 D<...

Greetings, Last night I manually unpresented and deleted a LUN (a SAN snapshot) that was presented to one node in a four node RAC environment running OCFS2 v1.4.1-1. The system then rebooted with the following error: Oct 21 16:45:34 ausracdb03 kernel: (27,1):o2hb_write_timeout:166 ERROR: Heartbeat write timeout to device dm-24 after 120000 milliseconds Oct 21 16:45:34 ausracdb03 kernel: (27,1):o2hb_stop_all_regions:1873 ERROR: stopping heartbeat on all active regions. I'm assuming that dm-24 was the LUN that was deleted. Looking back in the syslog, I...

All, This is hopefully the final drop of the patches for adding global heartbeat to the o2cb stack. The diff from the previous set is here: http://oss.oracle.com/~smushran/global-hb-diff-2010-10-07 Implemented most of the suggestions provided by Joel and Wengang. The most important one was to activate the feature only at the end, Also, got mostly a clean run with checkpatch.pl. Sunil

Please review the list of patches being applied to the ocfs2 1.4 tree. All patches list the mainline commit hash. Thanks Sunil

Hi, The following patches comprise the bulk of Ocfs2 updates for the 2.6.30 merge window. Aside from larger, more involved fixes, we're adding the following features, which I will describe in the order their patches are mailed. Sunil's exported some more state to our debugfs files, and consolidated some other aspects of our debugfs infrastructure. This will further aid us in debugging
