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:

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, i have a trouble with a ocfs2 partition. The "df -kh" command reports 63 GB of free space but only can use about 5 GB of this free space !! Then, the ocfs2 partition is wasting 58 GB of free space !!? df -kh S.ficheros Tama?o Usado Disp Uso% Montado en /dev/sda1 300G 238G 63G 80% /home/mail This are the mount options of the partition: mount /dev/sda1 on

I need add extra 2 nodes into current 3 nodes ocfs2 file system which means 5 nodes share this file system after it. I think this file system creates by mkfs.ocfs2 -b .. -N 4 .. which only allows 4 nodes. Questions: 1. How to verify parameter when this file system created? In this case, it is 4 nodes. 2. I assume I have to recreate the files system which will lost contains, if I use

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

Hi List, i'd like to share with you what happened yesterday. Kernel 2.6.36.1 ocfs2-tools 1.6.3 (latest). I had an old OCFS2 partition created with a 2.6.32 kernel and ocfs2 tools 1.4.5. I unmounted all partitions on all nodes in order to enable discontig-bg. I then used tunefs to add discontig-bg, inline-data and indexed-dirs. During indexed-dirs tunefs segfaulted and since then, fsck

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

Currently f_fsid of struct kstatfs returned from ocfs2_statfs() is undefined (at least it should be filled with 0). Since in some conditions, f_fsid value might be used as (f_fsid, ino) pare to uniquely identify a file, ocfs2 should return a defined unique f_fsid value from ocfs2_statfs(). This patch uses uuid_hash as a unique ID to initiate f_fsid value, the 32bits width is enough for ocfs2

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

Hi. I have a system storage HP MSA 2012 with 12 drives in it: 8 drives are 2 Tb each and 4 are 1 Tb each. All of them are in array RAID 1+0. This storage is connected to two servers which use data, stored on the storage. So I'm using OCFS2 on these two nodes. Today, after long time of successfull work with it, I've found that it has a limit of 32000 subdirs. The trouble is I have more than

Hi, I have a 2 nodes ocfs2 cluster running UEK 2.6.32-100.0.19.el5, ocfs2console-1.6.3-2.el5, ocfs2-tools-1.6.3-2.el5. My problem is that all the time when i try to run /etc/init.d/o2cb stop it fails with this error: Stopping O2CB cluster CLUSTER: Failed Unable to stop cluster as heartbeat region still active There is no active mount point. I tried to manually stop the heartdbeat with

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:~ #

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 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

Hello. I am experimenting with OCFS2 on Suse Linux Enterprise Server 11 Service Pack 1. I am performing various stress tests. My current exercise involves writing to files using a shared-writable mmap() from two nodes. (Each node mmaps and writes to different files; I am not trying to access the same file from multiple nodes.) Both nodes are logging messages like these: [94355.116255]

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.
