similar to: ping_pong using o2cb and cman

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

This is Hide. This is the first contribution. I'd like to configure cluster file system by OCFS2. The number of nodes are two. CompactFlash card(CF) is used as shared DISK. Guarantees of the writing frequency to CF are up to 100,000 times. However, it exceed in two day, due to the disk_heart_beat executed every two seconds. I tried following procedures to solve that. It seems solved. 1.

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 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,

I have a setup with 3 nodes running GlusterFS. gluster volume create myBrick replica 3 node01:/mnt/data/myBrick node02:/mnt/data/myBrick node03:/mnt/data/myBrick Unfortunately node1 seemed to stop syncing with the other nodes, but this was undetected for weeks! When I noticed it, I did a "service glusterd restart" on node1, hoping the three nodes would sync again. But this did not

Hi all, We have 2 mail servers sitting behind linux-HA machines.The mail servers are currently running dovecot 1.0rc2. Looking to enable GSSAPI authentication, I exported krb keytabs for imap/node01.domain at REALM and imap/node02.domain at REALM for both mail servers. However, clients are connecting to mail.domain.com, which results in a mismatch as far as the keytab is concerned (and rightly

-----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

Hi, I have added heartbeat mode as global, but when I do a mkfs and mount, and then check the mount, it says I am in local mode. Even /sys/kernel/config/cluster/ocfs2/heartbeat/mode says local. I am running CentOS with 3.x kernel, with ocfs2-tools-1.6.4-1118. mkfs -t ocfs2 -b 4K -C 1M -N 16 --cluster-stack=o2cb /dev/sdb mount -t ocfs2 /dev/sdb /mnt -o

Hello, I have a DELL MD3000i, and a couple of servers that I want to connect to the array. I have setup the main server with CentOS 5. - 2.6.18-53.el5 x86_64 - ocfs2-tools-1.2.7-1.el5 - ocfs2console-1.2.7-1.el5 - ocfs2-2.6.18-53.el5-1.2.8-2.el5 # Kernel Module And two OpenSuSe 10.3 Servers - 2.6.22.5-31-default x86_64 - ocfs2-tools-1.2.6-18 - ocfs2console-1.2.6-18 The module has been already

Hi, I attach 2 files in this email, the first is a Makefile and the second is jail.conf. For demonstre my idea i resolved create one "Pseudo Prototyping", for test is necessary: 1 - Create dir /usr/local/basejail 2 - Copy Makefile to /usr/local/basejail 3 - Copy jail.conf to /etc 4 - The initial basejail is precompiled is distributed in CD1, for simular basejail is necessary a

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

Hello Everyone, I just ran fsck.ocfs2 on /dev/drbd0 which is a one gig partition on a vm with limited resource (100meg of ram). I am worried that the process crashed because it has not responded in the past hour or so? fsck.ocfs2 /dev/drbd0 fsck.ocfs2 1.6.4 [RECOVER_CLUSTER_INFO] The running cluster is using the cman stack with the cluster name ASTCluster, but the filesystem is configured for

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

Hi, as far as I understand the current situation with locking looks like this: - o2cb supports cluster-aware flock(2). fcntl(2) locks are only local. - Pacemaker and cman also support cluster-aware fcntl(2) - There is no way for a userspace program to check if fcntl(2) is cluster- aware or not Is this correct? We would like to stick with the o2cb cluster stack but there are applications like
