Hi I have: SLES 10 SP2 (2.6.16.60-0.21-smp) ocfs2-tools-1.4.0-0.3 ocfs2console-1.4.0-0.3 and I can't change "heartbeat dead threshold" value. Content of /etc/sysconfig/o2cb: # O2CB_ENABLED: 'true' means to load the driver on boot. O2CB_ENABLED=true # O2CB_BOOTCLUSTER: If not empty, the name of a cluster to start. O2CB_BOOTCLUSTER=ocfs2 # O2CB_HEARTBEAT_THRESHOLD:

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">

Below are the o2cb driver configuration and the tail of my cluster.conf. Here is the error I get when trying to start my cluster: [root at pbx_1 ~]# /etc/init.d/o2cb online Starting O2CB cluster pbx: Failed o2cb_ctl: Memory allocation failed while setting cluster name Stopping O2CB cluster pbx: OK I figure I am running out of memory (1GB!?) Maybe the driver is not configured properly? If

Hi to all, this is My first time on this mailinglist. I have a problem with Ocfs2 on Debian etch 4.0 I'd like when a node go down or freeze without unmount the ocfs2 partition the heartbeat not fence the server that work well ( kernel panic ). I'd like disable or heartbeat or fencing. So we can work also with only 1 node. Thanks

Hi all, i am new to ocfs2. currently i am playing with ocfs on debian6 wich ocfs2 1.4. and also Oracle Enterprise Linux 5 & 6 with OCFS 1.6. The volume reside on an Dell MD3220i. When i set the active controller to offline, the client should initiate an failover to the second controller. this works, of only one clustermember is active for ocfs. At the moment there are two

Hi. I'm running RHEL4 for my test system, Adaptec Firewire controllers, Maxtor One Touch III shared disk (see the details below), 100Mb/s dedicated interconnect. It panics with no load about each 20 minutes (error message from netconsole attached) Any clues? Yegor --- [root at rac1 ~]# cat /proc/fs/ocfs2/version OCFS2 1.2.0 Tue Mar 7 15:51:20 PST 2006 (build

I am trying to mount the same partition from a KVM ubuntu 8.04.1 virtual machine and on an ubuntu 8.04.1 host server. I am able to mount the partition just on fine on two ubuntu host servers, they both talk to each other. The logs on both servers show the other machine mounting and unmounting the drive. However, when I mount the drive in the KVM VM I get no communication to the host

Hi all, I'm running OCFS2 on two system with OpenSUSE 10.2 connected on fibre channel with a shared storage (HP MSA1500 + HP PROLIANT MSA20). The cluster has two node (web-ha1 and web-ha2), sometimes (1 or 2 times on a month) the OCFS2 stop to work on both system. On the first node I'm getting no error in log files and after a forced shoutdown of the first node on the second I can see

Greetings ocfs2 folks, A client is experiencing some random deadlock issues within a cluster, wondering if anyone can point us in the right direction. The iSCSI connection seemed to have dropped on one node briefly, ultimately several hours later landing us in a complete deadlock scenario where multiple nodes (Node 7 and Node 8) had to be panic'd (by hand - they didn't ever panic on

Hi, everyone I have some questions with the OCFS2 when using it as vm-store. With Ubuntu 1204, kernel version is 3.2.40, and ocfs2-tools version is 1.6.4. As the network configure change, there are some issues as the log below. Why is there the information of "Node 255 (he) is the Recovery Master for the dead node 255" in the syslog? Why the host ZHJD-VM6 is blocked until it reboot

backgroud: there is a network idle timeout regarding which a node is considered dead or network partition occures. problem: for some product environment, there is a special time during a day. in this special time, a backup work is happening over private network. at the time that the backup is going on, there is very very high load on network. this can lead to ocfs2 network idle timeout and

Hello All, I have multiple OCFS2 clusters on SLES10 SP2 running Xen. We needed to increase the O2CB_HEARTBEAT_THRESHOLD from 31 up to 61 and did so successfully on 2 of our 3 clusters. However on one of the three clusters we are not able to change the value. The /etc/sysconfig/o2cb file contains 61 as the threshold after reconfiguring via /etc/init.d/o2cb configure, we reconfigure all 3 nodes at

Dear Sirs and Madams, I run a small visual effects production company, Hammerhead Productions. We'd like to have an easily extensible inexpensive relatively high-performance storage network using open-source components. I was hoping that OCFS2 would be that system. I have a half-dozen 2 TB fileservers I'd like the rest of the network to see as a single 12 TB disk, with the aggregate

Hello, I have two nodes running the 2.6.9-22.0.2.ELsmp kernel and the OCFS2 1.2.1 RPMs. About once a week, one of the nodes crashes itself (self- fencing) and I get a full vmcore on my netdump server. The netdump log file shows the shared filesystem LUN (/dev/dm-6) did not respond within 12000ms. I have not changed the default heartbeat values in /etc/sysconfig/o2cb. There was no other IO

I have set up an cluster with ocfs2 on top of drbd in primary/primary mode. As long as the datadir is in /var/lib/mysql, everything works fine. But as soon as I put the datadir on the ocfs2 filesystem /mnt/data/mysql mysql fails with: [Ubuntu] root at fs2:/etc# mysqld --safe-mode 090930 18:08:14 [Warning] Can't create test file /mnt/data/mysql/fs2.lower-test 090930 18:08:14 [Warning]

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

Hello all, are there any issues concerning ocfs2 (v 1.2.3) and device-mapper-multipath-0.4.5-12.0.RHEL4? I've build a 4 node cluster with two ocfs2 mounts on /dev/dm-0 and /dev/dm-1. Under heavy load the nodes dies after about two minutes reproducably ;-(( Once I've loaded the ocfs2 modules it seems to me that both modules (device-mapper-multipath related as well as ocfs related) are

We're trying to setup a dual-primary DRBD environment, with a shared disk with either OCFS2 or GFS. The environment is a Centos 5.3 with DRBD82 (but also tried with DRBD83 from testing) . Setting up a single primary disk and running bonnie++ on it works. Setting up a dual-primary disk, only mounting it on one node (ext3) and running bonnie++ works When setting up ocfs2 on the /dev/drbd0
