hi! i'm on debian lenny and trying to run ocfs2 on a dual primary drbd device. the drbd device is already set up as msDRBD0. to get dlm_controld.pcmk i installed it from source (from cluster-suite-3.0.10) now i configured a resource "resDLM" with 2 clones: primitive resDLM ocf:pacemaker:controld op monitor interval="120s" clone cloneDLM resDLM meta

hello, i opened a bug on the ocfs2 bugzilla reporting difficulty i have utilize a different cluster stack than o2cb. link: http://oss.oracle.com/bugzilla/show_bug.cgi?id=1325 to summarize i'd like to use ocfs2 on an ubuntu server with drbd and ctdb. ctdb requires fcntl locks for its lock files. however o2cb doesn't provide that functionality whereas cman (redhat's cluster manager

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

I have been reading loads of threads over different mailing lists about ocfs2_controld, so have anyone ever built Cluster stack (openAIS, pacemaker, corosync + OCFS2 1.4) from source and got o2cb agent working with pacemaker?

Hi Greg, The following two patches move /sys/o2cb into /sys/fs/o2cb as we previously discussed. A symlink is created to maintain compatibility with existing versions of ocfs2-tools. A patch to automatically search /sys/fs/o2cb has been committed to the ocfs2-tools repo and a release with that code shouldn't be too far out. Old versions of ocfs2-tools have been tested and work fine with the

Hi, I am trying to understand file locking and share modes. I am using RedHat Enterprise Linux 4, with kernel 2.6.9-55.ELsmp, samba-3.0.10-1.4E.11 and Windows XP. In particular I am looking at a machine running Linux exporting its local filesystem using Samba, with a Windows client accessing the file share. If I use byte range locking (fcntl() on Linux, LockFile() on Windows) things work as

Hi, I might be overlooking the obvious, but I have yet to find "/etc/init.d/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,

Hello, this is my scenario: 1)I've created a Pacemaker cluster with the following ocfs package on opensuse 11.3 64bit ocfs2console-1.8.0-2.1.x86_64 ocfs2-tools-o2cb-1.8.0-2.1.x86_64 ocfs2-tools-1.8.0-2.1.x86_64 2)I've configured the cluster as usual : <resources> <clone id="dlm-clone"> <meta_attributes id="dlm-clone-meta_attributes">

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?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Folks, When I installed ocfs2 the first time and setup oracle to work with it, the clustername defaulted to "ocfs2". We are testing adding new nodes, but we would like to add new nodes to the o2cb cluster in a different clustername. Do I need to do anything to keep that separate on the filesystem. I just want to make sure that when

Dear All, Would like your advise if anyone have setup ocfs2 on oracle Linux 7 (free) with corosync and also pacemaker. I've search the net but all guide seem to be dated to 2012 and somehow outdated or I don't get it. I know that the ocfs2 default cluster lock o2cb don't support lock CTDB need thus need to change that to pacemaker and corosync. Please help. Regards, Min Wai.
