I have seen many references online to being able to use OCFS2 with Pacemaker, but the documentation I have been able to find is very Sparse. I have kernel 2.6.29, and the latest DLM and Pacemaker (using openais) and OCFS2-Tools from GIT. (As of June 13). I was able to build ocfs2_controld.pcmk ... (With some minor changes to the makefile for my install) I noticed the OCF version of o2cb is not in the latest git snapshot of OCFS2-Tools I downloaded.

Hello, We are having a problem with a 3-node cluster based on Pacemaker/Corosync with 2 primary DRBD+OCFS2 nodes and a quorum node. Nodes run on Debian Squeeze, all packages are from the stable branch except for Corosync (which is from backports for udpu functionality). Each node has a single network card. When the network is up, everything works without any problems, graceful shutdown of

Hi Guys, I overhauled and simplified the Pacemaker hooks recently. This patch: - Reuses more code from the Pacemaker libraries - Escalates fencing to the cluster manager instead of initiating it directly Attached patch is against master, or you can pull the original patch which is against an older version used by SUSE:

Howdy! I have ocfs2 set up on a cluster running pacemaker and openais. When setting up ocfs2 using service o2cb configure, do I need to specify a different cluster stack besides o2cb?

Hello Fellow CentOS users. I was hoping to get some information on Pacemaker clusters using OCFS2 on CentOS 6.x. In my initial attempts to get this to work, I realized that Pacemaker is packaged much differently on CentOS than it is on Debian or SUSE. For example, /usr/sbin/dlm_controld.pcmk is missing and ocfs2-tools is nowhere to be found. Users could of course pull in packages from say Oracle Enterprise Linux, but I was curious as to why this is the case? Is OCFS2 not supported on CentOS? Thanks for the insight.

Hi all, tracing a couple of reports here (on a somewhat older version of OCFS2, with a user-space/pacemaker/dlm_controld.pcmk stack) where we see fnctl(F_SETLK) return ENOSYS. This happens after a node has failed/been fenced and recovered. It affects only individual mounts, not the whole system. The only code path that I can see so far that could lead to ENOSYS being returned here is from within dlm_controld:process_ploc...

Hi, According to comments in file fs/ocfs2/cluster/quorum.c:70 about the self-fencing operations : /* It should instead flip the file ?* system RO and call some userspace script. */ So, I tried to add it (but i did'nt find a way to flip the fs in RO). Here is a proposal for this functionnality, based on ocfs2-1.4.7. This patch add an entry 'fence_cmd' in /sys to specify an

Hello. I am experimenting with OCFS2 on Suse Linux Enterprise Server 11 Service Pack 1. I am performing various stress tests. My current exercise involves writing to files using a shared-writable mmap() from two nodes. (Each node mmaps and writes to different files; I am not trying to access the same file from multiple nodes.) Both nodes are logging messages like these: [94355.116255]
