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

Hi, we have a 2 node / 3 node RAC installation with OCFS. We have the following observations. 1. TIME STAMP Issue We have noticed that the time stamp which is shown on the datafiles doesnt remain the same even after a shutdown normal /shutdown immediate i.e If I shutdown all RAC instances ( A , B , C) using shutdown normal / immediate, the timestamp on the datafiles are not the same. Even

Hi Sunil, I had filed a bug and saw your response stating that it would be fixed in version 14. In the meanwhile , what we want to know is whether this bug is a minor bug and can be ignored for now. Does reporting 100% inodes cause any problem for the OCFS file system or can we ignore this bug and go into production. Also can you tell us by when version 14 would be released. R'gds

Hi OCFS Gurus... I have 2 questions for OCFS ver 1.0.10.1 1. What is the Maximum mount point suggested if we are using OCFS ? 2. Is there any method to tune the OCFS to booster the IO performance? Awaiting ur responses... Thanks in Advance... Rgds/Jeram

I am starting to see a few issues with OCFS and 9.2.0.3 RAC on redHat Linux AS 2.1. Wondering if there is anyone out there experiencing similar issues... a few pointers to the issues.. 1. OCFS read/write performance is way lower than a read/write to a raw device.. i can give you some comparison numbers.. 2. Writes to shared disk with ocfs would get locked up by one server.. it doesnt have to

Dear all... Currently I am having 5 RAC nodes with Configurations as below : 1. HW = DL580 32 Bit Processor 2. OS = RHAS 2.1 3. OCFS= Latest Version 4. RAC= Oracle9i 9.2.0.5 (32 Bit) Now I am planning to add 2 more Rac Nodes in the existing RAC: 1. HW=Itanium 64 bit processor 2. OS=RHAS 3.0 3. OCFS=Latest Version 4. RAC=Oracle9i 9.2.0.5 (32 bit) Can I

Wim, Thanks for your prompt response on this. The tpmC figures look very impressive, and tpmC is read intensive. I had already read note 236679.1 "Comparing Performance Between RAW IO vs OCFS vs EXT2/3" which I guess is the article to which you are referring; it made me suspect that the poor performance was due to the lack of an OS IO cache but I wasn't sure. The database is

Hi all, Sorry to break in, but I find this thread a bit interesting. Jeram: I'm not very familiar with HP storage and cannot find too much info on the EVA 6000 array. Is it related to the EVA 5000 somehow, or is it a NAS array? In any case, how is the array configured. If the algorithm for hartbeat is as described earlier (36 sector reads and one write per second (per host???)) then you

Hi, well i mounted the OCFS drive over nfs, but it seems to have problems with it, because the NFS does not detect changes (if I add or delete files) the nfs shares still shows the old status. If i delete a file on the OCFS volume, and i am doing a "ls" on one of the nfs clients, it says for every file which was on the ocfs, "no such file or directory". Did I miss

(Yep, it's me again) We've worked around some minor glitches and now have a pair of nodes happily sharing an OCFS volume. I was wondering, though, if it was possible to configure a second private IP address so that the nodes could communicate over more than one Gigabit Ethernet connection. Our RAC books and online docs make some vague references to multiple interconnects, but I have yet

>also - for async io ; >p2448994_9204_LINUX.zip is the patch to apply for oracle >(this is metalink ARU patch number). Wim, The patch description on Metalink says: DIRECT IO SUPPORT ON EXT2 FILESYSTEM Which wasn't quite what I was expecting.

A few weeks back we opened a TAR with Oracle support to determine whether an OCFS (1.0.9-12) + async configuration was considered supportable. At first a technician said yes, but I followed up with Wim's explanation of how that combination is potentially troublesome and inadequately tested. The technician double-checked, then confirmed that OCFS + async is considered risky. He did say that a

Hi all... I have a strange problem. 2 of my mount points already use 7% of space, even when I check the directory is empty. When I re-format it, it release the space for a while, after 1 or 2 days, the space is used again for 7% - 10 %. What could be the reason? I am using RHAS 2.1 Enterprise Kernel 2.1 and OCFS release 1.0.9-6 Thanks Jeram
