We have a setup with 15 hosts fibre attached via a switch to a common SAN. Each host has a single fibre port, the SAN has two controllers each with two ports. The SAN is exposing four OCFS2 v1.4.2 volumes. While performing a failover test, we observed 8 hosts fence and 2 reboot _without_ fencing. The OCFS2 FAQ recommends a default disk heartbeat of 31 - 61 loops for multipath io users. Our initial

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.

We just installed a new cluster with 6 HP DL380g5, dual single port Qlogic 24xx HBAs connected via two HP 4/16 Storageworks switches to a 3Par S400. We are using the 3Par recommended config for the Qlogic driver and device-mapper-multipath giving us 4 paths to the SAN. We do see some SCSI errors where DM-MP is failing a path after get a 0x2000 error from the SAN controller, but the path gets puts

Hi there I recently installed an OCFS2 filesystem on our FC-SAN. Everything seemed to work fine and I could read & write the filesystem from both servers that are mounting it. After a while though, writes coming from one node do not appear on the other node and vice versa. I am not sure what's causing this, and not very experienced at debugging filesystems. If anybody has any

Hi, Sunil or Tao, I have a 4 nodes OCFS2 cluster running OCFS2 1.2.8 on SuSE 9 SP4. When I tried to do failover testing (shutting down one node), the whole cluster hung (I can not even login to any server in the cluster). I have to bring all of them up and then be able to use the system. What kind of behavior is it? Is it the fence of OCFS2? Below is my configuration. aopcer13:~ #

Hello OCFS2 team, I'm currently looking at the OCFS2 code in linux-2.6.17.11, and i wander why OCFS2 performs its heartbeat on a disk region unlike on the network like many clustered services stack do. What is the requirement for a disk heartbeat ? Is there any way to tune this behaviour and change it into a network heartbeat ? -- Mathieu

Hello, How to mount a disk with ocfs2 FS in one node to another . Let ys say I have /dev/sda mounted on /u01 in node 1 . I need to access it from nod2 . Any solutions ?

Hi guys I installed ocfs2 on 4 node (redhat 4u3) on shared FC devices ( EMC storage ). So I've noticed several problems: 1. When I restart first node, it shutdown so slow and I have to power off machine. What is the problem, heartbeat timeout, dlm ? 2. What will happen when I plug off network cabel ( for interconnect ). What shoud I do, unmount ocfs2 volume on each node, stop ocfs2

Greetings, Last night I manually unpresented and deleted a LUN (a SAN snapshot) that was presented to one node in a four node RAC environment running OCFS2 v1.4.1-1. The system then rebooted with the following error: Oct 21 16:45:34 ausracdb03 kernel: (27,1):o2hb_write_timeout:166 ERROR: Heartbeat write timeout to device dm-24 after 120000 milliseconds Oct 21 16:45:34 ausracdb03 kernel:

Hi, I want to share a partition of an external disk between 3 machines. It is located on a Sun StoreTek 3510 and bound (via multipathing) to all 3 machines. One machine (say mach1) is the node I used to create the filesystem and setup /etc/ocfs2/cluster.conf. I copied the file to the other 2 machines. All use the same /etc/multipath.conf[1], too. All start /etc/init.d/ocfs2 at boot, all are

Hi, I have installed and configured ocfs2 as per the given guidelines on two nodes.

When I try and run the mkfs.ocfs2 command after I have updated all of the other nodes in the cluster with the new node information in cluster.conf I am getting the following error: mkfs.ocfs2 -b 4k -C 32K -L "ocfs2" -N 4 /dev/sdb1 mkfs.ocfs2 1.4.4 Cluster stack: classic o2cb Overwriting existing ocfs2 partition. mkfs.ocfs2: Could not create domain while initializing the dlm As this is

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

Hi, Does OCFS require NAS hardware to run or does normal PC hard disk work? Thanks, Pete -------------- next part -------------- An HTML attachment was scrubbed... URL: http://oss.oracle.com/pipermail/ocfs2-users/attachments/20081219/1bc9110b/attachment.html

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

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
