I've been using OCFS2 on a 3 way Centos 5.2 Xen cluster for a while now using it to share the VM disk images. In this way I can have live and transparent VM migration. I'd been having intermittent (every 2-3 weeks) incidents where a server would self fence. After configuring netconsole I managed to see that the fencing was due to a heartbeat threshold timeout so I have now increased

As we have fiber channel, and we have fiber connections, sometimes direct p-to-p, where we could run it into our fiber channel switch, and share a disk array over hundreds of feet, to hundreds of miles, but where servers wouldn't be able to talk via fast enough network connection, does (or will) ocfs2 support a mode where there is no network connection needed, and all voting, and cluster

I have an OCFS2 filesystem on a coraid AOE device.

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, 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

All, This is hopefully the final drop of the patches for adding global heartbeat to the o2cb stack. The diff from the previous set is here: http://oss.oracle.com/~smushran/global-hb-diff-2010-10-07 Implemented most of the suggestions provided by Joel and Wengang. The most important one was to activate the feature only at the end, Also, got mostly a clean run with checkpatch.pl. Sunil

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

Found 15 patches (out of 162) that appeared relevant to ocfs2 1.4. Please review. Sunil

Hi Linus, Here are some 2.6.20 fixes for ocfs2. The patch by Zhen Wei isn't really a fix, but a very small amount of support for a feature which is mostly implemented in ocfs2-tools. Considering it's just a single attribute export via configfs, I'd say it's pretty safe to merge. Please pull from 'upstream-linus' branch of

Hello. I plan to use OCFS2 + DRBD for email server. Problem: I use "seeker" for testing http://www.linuxinsight.com/how_fast_is_your_disk.html And get this: Results: 65 seeks/second, 15.23 ms random access time Then I do rm of many files - it fals to 10 seeks/second and performance is terrible. What can I do to increase it? What`s wrong? Below is many info. What we have: Debian

I have a suggestion about the heartbeat and the way that "downed node" detection works. There are occasions where a node is up, and for whatever reason, I need to power cycle it (for instance, a frozen process, etc). In these instances, my other nodes are unable to perform file system operations until the heartbeat period expires. This ends up being somewhere around 30-60 seconds (this

Hello, Any word on when extended attribute support will be added to OCFS2? What are the impediments to someone implementing this? Alternatively, has anyone implemented a patch to add extended attribute support to OCFS2? I've been watching the open source Lustre fs development, too. I noticed that they have added extended attribute support. However, OCFS2 is more attractive for some

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:

Currently the process of dlm join contains 2 steps: query join and assert join. After query join, the joined node will set its joining_node. So if the joining node happens to panic before the 2nd step, the joined node will fail to clear its joining_node flag because that node isn't in the domain map. It at least cause 2 problems. 1. All the new join request will fail. So no new node can mount

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

I'm configuring a HA-cluster to share disks using heartbeat from http://www.linux-ha.org/ Two machines, lets call them server1 and server2 share the same disk with an ocfs2 file system. However, the two machines have separate disks for their OS installations. The two physical servers have two gigabit nics each and on those nics I place four virtual IP addresses which heartbeat makes sure is
