OCFS and backups to tape
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

Unable to delete a file...
Hello all, I'm using OCFS version 1.0.15-PROD5 on RHAS3 Update 4. My RMAN script for delete obsolete fails. Debugging problem I've found that is not able to remove a file. Seems that this file is in use and any operation is not possible. Reading metalink I've found some docs about problem with cp/mv/dd/tar on files under OCFS and suggestion is always to use option --o_direct. In my

ocfs seek-performance
hi list, i have a little problem with 2-node RAC using OCFS. the application running on this cluster does heavily index-based accesses. the data volumes are SAN volumes connected by fibrechannel. the throughput does not exceed 10mb/s, average is 7-8 mb/s. i've used 'iostat -x' and got rkB/s=8000 while %util=100% (device was saturated) from kernel's POV. i did some

Rsync with OCFS (RAC)
Hello All We currently use rsync for various jobs at our company. We are now looking at using it to create an offsite synchronized copy of an Oracle 10g RAC archive logs area. The source area is on Oracle OCFS file system. The OCFS filesystem requires all reads/writes to be performed with the O_DIRECT option, thus bypassing cache. Oracle provide an updated coreutils package which includes the

OCFS file system used as archived redo destination is corrupted
we started using an ocfs file system about 4 months ago as the shared archived redo destination for the 4-node rac instances (HP dl380, msa1000, RH AS 2.1) . last night we are seeing some weird behavior, and my guess is the inode directory in the file system is getting corrupted. I've always had a bad feeling about OCFS not being very robust at handling constant file creation and deletion

H(U): A few OCFS questions
OCFS Experts, Sorry if the questions below are naive, or were answered before, but here it goes. I have a potential client who at the moment having problems installing 10g RAC on RHEL 3.0 (2.4.21-20). They using (rather planning to use) OCFS for everything, including CRS files (OCR, voting). Questions: 1) They use custom kernel (modified by their security people). Do we support OCFS on the

ocfs2 questions
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

FW: Observations
Hi Sunil, I'm looking into this thread now. Does this mean we cannot use FTP option to copy OCFS files to ext3? If so, is there any ftp version available for OCFS, similar to cp --o_direct? Also, is there any version of sync available for OCFS (in normal FS, sync does a refresh of FS from kernel cache so that the FS is consistent). By this can we say that the FS shard by both nodes is

Moving ocfs file system to a new SAN
Hi, We are currently rolling over our SAN (FC4700 to CX700) and have now reached the data migration stage. I need to move the data files on my current /u01 ocfs file system (on FC4700) to a new ocfs file system (on CX700) which I want to keep as the same /u01 mount point on the hosts. With a normal file system I would just mount the new file system to a temporary mount point, copy the data,

About compression of files on OCFS
Hi, Experts. I'm Kenichiro Ochi, the support engineer of Oracle Japan. I would like to ask you the following questions about supported files on OCFS. I know OCFS VER 1.X only supports Oracle datafiles (including archive logfiles). My customer has one question. - Is it supported that archive logfiles on OCFS are compressed (using compress, gzip command etc) ? In other words, is it
