...o2cb" however, I read that configuration uses this init script. Where is it? From: ocfs2-tools-1.2.4/README.O2CB [Starting the OCFS2 Clustering Services] O2CB is comprised of a simple node manager, heartbeat, TCP protocol, and DLM. The basic steps in startup are as follows: 1) Load the nodemanager, heartbeat, and tcp modules 2) Mount the nodemanager and heartbeat pseudo filesystems. 3) Load the cluster information via o2cb_ctl. This adds all the known nodes to the nodemanager's psuedo filesystem. 4) Load the DLM module. 5) Load the OCFS2 module. 6) Mount an OCFS2 filesystem. The /...

...where o2net used to call o2quo functions directly, it now injects the O2HB_CONN_{UP,DOWN}_CB events. * o2net knowledge of o2quo in header files has been moved to quorum.h * o2net's handling of quorum decisions on connection failure has been moved to o2quo. * o2quo is initialized by the nodemanager rather than by o2net. ******* Unfortunately, this code is actually broken. It will cause a deadlock when umounting the last file system due to a deadlock on o2hb_callback_sem. Don't actually use this code; It's just posted for review ******* fs/ocfs2/cluster/heartbeat.c | 14...

This is a forward port for net_proc.c from 1.2.

Added two debugfs entries... one to dump o2hb livenodes and the other to dump osb. $ cat /sys/kernel/debug/ocfs2/BC4F4550BEA74F92BDCC746AAD2EC0BF/fs_state Device => Id: 8,65 Uuid: BC4F4550BEA74F92BDCC746AAD2EC0BF Gen: 0xA02024F2 Label: sunil-xattr Volume => State: 1 Flags: 0x0 Sizes => Block: 4096 Cluster: 4096 Features => Compat: 0x1 Incompat: 0x350 ROcompat: 0x1

The versioning information is confusing for end-users. The numbers are stuck at 1.5.0 when the tools have moved to 1.8.3. I suggest removing the versioning system in the kernel altogether and let the kernel version be the guide to debug issues. However, if you think versioning is still required, please state the reason and modify the version string in the ver.* files to reflect the uptodate

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

The following series of patches comprises the bulk of our outstanding changes for Ocfs2. Aside from the usual set of cleanups and fixes that were inappropriate for 2.6.25, there are a few highlights: The '/sys/o2cb' directory has been moved to '/sys/fs/o2cb'. The new location meshes better with modern sysfs layout. A symbolic link has been placed in the old location so as to
