similar to: What could cause slow down betwen OCFS2 1.2.9 and 1.4.4

We are setting up 2 new EL5 U4 machines to replace our current database servers running our demo environment. We use 3Par SANs and their snap clone options. The current production system we snap clone from is EL4 U5 with ocfs2 1.2.9, the new servers have ocfs2 1.4.3 installed. Part of the refresh process is to run fsck.ocfs2 on the volume to recover, but right now as I am trying to run it on our

Hi there, A month ago we ran into the fsck issue while rebooting one of the Oracle RAC nodes running on Linux RHEL 5.2. It was hanging for 1.5 hours During the reboot, OS portion went fine, then it activated the data volumes in all data vg's with [OK] Then displayed message: Checking filesystems - and it took it 1.5 hrs, then it finished the reboot. Last weekend we rebooted the same box and

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

We got a remote Oracle 10g R2 standby running on OCFS2. Initial when we started the standby, read I/O was < 5MB/sec on average. Since then it has grown to over 40MB/sec (longer average, it peaks much higher). Here is a graph showing this: http://www.alameda.net/~ulf/dbphx01.png We also have a local standby running (on EXT3) which is not showing the same symptom. I am trying to find where all

Hello everyone, once again. We are running into a problem, which has shown now 2 times, possible 3 (once the systems looked different.) The environment is 6 HP DL360/380 g5 servers with eth0 being the public interface, eth1 and bond0 (eth2 and eth3) used for clusterware and bond0 also used for OCFS2. The bond0 interface is in active/passive mode. There are no network errors counters showing and

I am working currently on cloning on a regular basis our production OCFS2 volumes to our test environment. For the database (Oracle 10G R2 RAC) we put it into backup mode, then execute a Snapclone on our 3Par SAN. Then we use RemoteCopy and SnapClone to our development 3Par SAN. To recover the OCFS2 volume I got through the following steps: Stop database umount /export/<volume name> Log

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 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

I get the following error when trying to mount: Nothing changed (in any case not that I know of). I get the same error from both nodes. Please assist. # mount /u02 mount.ocfs2: Invalid argument while mounting /dev/sdd1 on /u02. Check 'dmesg' for more information on this error. /etc/fstab: /dev/sdd1 /u02 ocfs2 _netdev,datavolume,nointr 0 0

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, I have two OCFS file file systems mounted at /ocfs_1 and /ocfs_2. I have unmounted both OCFS file systems and was trying to then offline and unload OCFS. The offline command failed with - # ./o2cb offline Stopping O2CB cluster ocfs2: Failed Unable to stop cluster as heartbeat region still active Looking at the processes on this box shows a number of OCFS processes are still active -

Hello... it was put under my attention that a partition we have in one of our production system was displaying wrong size with df command.... 123 GB... but in fact the size of all the files is a mere 15 GB.... What is going on? Shall we use ocfs.fsck to fix that? Is strange... Thanks for any comment.... Raymundo Garcia ________________________________ The information contained in this message

I have a relatively new test environment setup that is a little different from your typical scenario. This is my first time using OCFS2, but I believe it should work the way I have it setup. All of this is setup on VMWare virtual hosts. I have two front-end web servers and one backend administrative server. They all share 2 virtual hard drives within VMware (independent, persistent, &

Hi ocfs2 developers, there are some news about the schedule for a new ocfs2 release that solve the actual bug/limitations?

Hello, I'm writing from the otherside of the world from where my systems are, so details are coming in slow. We have a 6TB OCFS2 volume across 20 or so nodes all running OEL5.4 running ocfs2-1.4.4. The system has worked fairly well for the last 6-8 months. Something has happened over the last few weeks which has driven write performance nearly to a halt. I'm not sure how to proceed, and

Hello, we have a pair of IBM P570 servers running RHEL5.2 kernel 2.6.18-92.el5.ppc64 We have Oracle RAC on ocfs2 storage ocfs2 is 1.4.7-1 for the above kernel (downloaded from oracle oss site) Recently both servers have been crashing with the following error: Assertion failure in journal_dirty_metadata() at fs/jbd/transaction.c:1130: "handle->h_buffer_credits > 0" kernel BUG in

Currently f_fsid of struct kstatfs returned from ocfs2_statfs() is undefined (vfs layer fills 0 as default). Since in some conditions, f_fsid value might be used as (f_fsid, ino) pair to uniquely identify a file, ocfs2 should return a unique defined f_fsid value from ocfs2_statfs(). Because uuid_str is identified no mater on big or litlle endian machine, it's also endian consistent to use
