similar to: OCFS2 v1.4 hangs

Hi All, I have a cluster of four nodes and one will not join the cluster. I have two IPs on each node, one external and one internal. I have tried changing around the IPs in the /etc/ocfs2/cluster.conf and that helped - at least I recovered three of the machines. Any suggestions on where else to look? Best Regards John (23359,2):o2net_connect_expired:1637 ERROR: no connection established with

Greetings. Is there an approved way to aggregate LUNs when using OCFS2? I have several 1TB LUNs I'd like to make into a single filesystem. Would I use something like Linux software raid? Brett

Hello All, We're hosting DB1 and DB2 with db_block_size set to 8K, 16K respectively File system creation is done with mkfs.ocfs2 -b 4K -C 32K -N 4 -L LABLE /dev/mapper/xxxx Mount is done with: ocfs2 _netdev,datavolume,nointr 0 0 I'd like to know if we can separate most of the tablespaces on different LUNs, even if they're on the same disk group sometimes, is it

Hi, I have 2 NIC and wants to use both NIC for load balancing and fault tolerance. - Quick question if NIC bonding in Redhat is supported by OCFS2? - If yes which mode bonding is supported? Thanks Raheel -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I'am new to ocfs2 filesystem and I have some questions about it. I installed three server according to the user guide from http://oss.oracle.com/projects/ocfs2/dist/documentation/v1.4/ocfs2-1_4-usersguide.pdf For every single server I have a working ocfs2 partition /dev/sdb1 on /mnt/oc1 type ocfs2 (rw,_netdev,heartbeat=local) As I understand the ocfs2 system I can use now these

Hi, I'm planning to upgrade an old public/internal development infrastructure and will use CentOS 5.4 x86_64 as basis. One of the critical server is Subversion (as an Apache httpd module). We currently use Subversion v1.4 on the server and v1.6 on our clients. While I was very happy with the v1.4 server over the years, we now sometimes have weird issues which seem related to compatibility

Hi All, Eagerly waiting for v1.4.x to mature a bit before getting serious about it. Is it ready for production yet? If that's too general, where is it in terms of stability compared to where 1.2.x is now. Anyone running it successfully in production environment and if so what sort of config do you have?

Hi all, on my nodes I have another cluster manager running that takes care of fencing the node, is it safe to disable ocfs2 self-fencing? Details: I'm using ocfs2 over drbd in master/master aka primary/primary mode. In case of loss of network connectivity I would like to disconnect the drbd device, invalidate it and unmount the filesystem but ocfs2 reboots the node.... Is it possible to

I have an OCFS2 filesystem on a coraid AOE device. It mounts fine, but with heavy I/O the server self fences claiming a write timeout: (16,2):o2hb_write_timeout:164 ERROR: Heartbeat write timeout to device etherd/e0.1p1 after 12000 milliseconds (16,2):o2hb_stop_all_regions:1789 ERROR: stopping heartbeat on all active regions. Kernel panic - not syncing: ocfs2 is very sorry to be fencing this

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

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

Hello! Hey didnt a setting for the 10 second network timeout get into the 2.6.20 kernel? if so how do we set this? I am getting OCFS2 1.3.3 (2201,0):o2net_connect_expired:1547 ERROR: no connection established with node 1 after 10.0 seconds, giving up and returning errors.

Hi, According to comments in file fs/ocfs2/cluster/quorum.c:70 about the self-fencing operations : /* It should instead flip the file ?* system RO and call some userspace script. */ So, I tried to add it (but i did'nt find a way to flip the fs in RO). Here is a proposal for this functionnality, based on ocfs2-1.4.7. This patch add an entry 'fence_cmd' in /sys to specify an

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:~ #

Does anyone have any experience with Emulex HBA cards (LP10000) using OCFS2, Linux AS4 U4 x86_64 AMD? I'm trying to find out whether this is a verified combination, if anyone has successfully used it. I have that hardware/sofware combination, and am experiencing stability/performance/panic/hang issues with OCFS2. -------------- next part -------------- An HTML attachment was scrubbed... URL:

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 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

One more follow on, The combination of kernel.panic=60 and kernel.printk=7 4 1 7 seems to have netted the culrptit: E01-netconsole.log:Jan 18 09:45:10 E01 (10,0):o2hb_write_timeout:137 ERROR: Heartbeat write timeout to device dm-12 after 60000 milliseconds E01-netconsole.log:Jan 18 09:45:10 E01 (10,0):o2hb_stop_all_regions:1517 ERROR: stopping heartbeat on all active regions.

By default, o2cb fences the box by calling emergency_restart(). While this scheme works well in production, it comes in the way during testing as it does not let the tester take stack/core dumps for analysis. This patch allows user to dynamically change the fence method to panic() by: # echo "panic" > /sys/kernel/config/cluster/<clustername>/fence_method Signed-off-by: Sunil

Hello all. I would like to canvas some opinions on options for shared storage in a Xen cluster. So far I've experimented with using iSCSI and clvm which mixed success. The primary concern I have with both of these options is that there seems to be no obvious way to ensure exclusive access to the LUN/device to the VM I want to run. On a couple of occasions during my playing I've
