similar to: new ocfs2 release?

Does anybody knows if is there a certified procedure in to backup a RAC DB 10.2.0.3 based on OCFS2 , via split mirror or snaphots technology ? Using Linux LVM and OCFS2, does anybody knows if is possible to dinamically extend an OCFS filesystem, once the underlying LVM Volume has been extended ? Thanks in advance Riccardo Paganini

Hi, When attempting to restore to LINUX RHEL5 - OCFS2 filesystem received the following error during RMAN restore for nearly all of the datafiles attempted to restore with exception of a couple of smaller datafiles which were smaller < 2GB.

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

Hi everyone. Does anyone know why the user-space heartbeat (linux-ha) patches from SuSE / Novell are not commited to the mainline ocfs2 source tree? Or are they? Is there an easy way (which does not break the distros package management) to apply these? Thanks, Christian

Changelog from V1 to V2: 1. Modify some codes according to Mark's advice. 2. Attach some test statistics in the commit log of patch 3 and in this e-mail also. See below. Hi all, In ocfs2, when we create a fresh file system and create inodes in it, they are contiguous and good for readdir+stat. While if we delete all the inodes and created again, the new inodes will get spread out and that

Afternoon, We have an ocfs2 release 1.4 filesystem shared between two nodes (RHEL5). The filesystem in question is used exclusively for Oracle RMAN backups. A df -h shows the following: [root at imsthdb07 ~]# df -h /data/orabackup Filesystem Size Used Avail Use% Mounted on /dev/mapper/eva_mpio_myserver07_08_oracle_bkup0 250G

Hi! Seems we're facing some memory leak here. This is vanilla 2.6.19-rc6 on a x86_64 box, 4GB RAM. A simple `ls -Rn' on a filesystem with lots of files makes the box leak so much RAM that the OOM killer starts to kick in. With slab alloc debugging turned on, we see this: # mount; ls -Rn; wait some seconds; Ctrl-C [root@lnxp-1038:/backend1]$ cat /proc/slab_allocators | egrep

We are in the process of upgrading to OCFS2. We have recently restored our Production Database to a Development platform configured with OCFS2 with RMAN. No problems. As for the Production migration, we understand that you cannot mount an OCFS volume (our current configuration) with OCFS2. We are interested in mounting an EXT3 file system, performing a cold RMAN backup, copying the datafiles

I have a 2 node cluster of HP DL380G4s. These machines are attached via scsi to an external HP disk enclosure. They run 32bit RH AS 4.0 and OCFS 1.2.4, the latest release. They were upgraded from 1.2.3 only a few days after 1.2.4 was released. I had reported on the mailing list that my developers were happy, and things seemed faster. However, twice in that time, the cluster has gone down due

Hi, we have installed ocfs2 on Rhat 4. It is being used as a general clustered file system. There are no oracle binaries or datafiles on the ocfs volume. So no need for RMAN or oarcle agents etc etc. The customer would like to backup the volume using arcserve. However CA are saying that they cannot backup from an ocfs volume. Has anyone out there got any words of wisdom about backing up

Hello, I have found, that ocfs2 is very slow when doing I/O operation without cache. See a simple test: ng-vvv1:~# dd if=/data/verejna/dd-1G bs=1k | dd of=/dev/null 1048576+0 records in 1048576+0 records out 1073741824 bytes (1.1 GB) copied, 395.183 s, 2.7 MB/s 2097152+0 records in 2097152+0 records out 1073741824 bytes (1.1 GB) copied, 395.184 s, 2.7 MB/s The underlying block device is quite

Good morning, I'm trying to build ocfs2-1.4.7 against a Centos 5.3 distro with a 2.6.30 kernel. I get the following errors during compilation. make[1]: Entering directory `/root/src/ocfs2-1.4.7/fs' make -C ocfs2 stamp-md5 make[2]: Entering directory `/root/src/ocfs2-1.4.7/fs/ocfs2' make[2]: Leaving directory `/root/src/ocfs2-1.4.7/fs/ocfs2' make -C ocfs2/cluster stamp-md5

In ocfs2, the inode block search looks for the "emptiest" inode group to allocate from. So if an inode alloc file has many equally (or almost equally) empty groups, new inodes will tend to get spread out amongst them, which in turn can put them all over the disk. This is undesirable because directory operations on conceptually "nearby" inodes force a large number of seeks. So

Hello Ladies and Gents .. First time poster ..

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

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

Hi, I'm trying to compile ocfs2 1.2.6 on a 2.6.21 kernel (with rsbac and pax patches), but I can't get this to work .. In 2.6.20 there was an change in the definition of the INIT_WORK macro (http://lkml.org/lkml/2006/12/5/269) this seems to cause my problems (see below) but even after removing the third parameter of the INIT_WORK calls the compile fails (see second compile failure).
