...:) this is a consistently recurring error at my site. we can't put RAC into production if it's going to hang due to some race condition when i try to create a file. how is it that noone else has seen this problem?

We are running Linux AS 2.1 .27 enterprise on an EMC CX400 SAN with ocfs version enterprise 1.0.9-12. After formatting the partitions the response from the filesystem is very slow during either read or writes. Even worse, while we can create a directory, we are unable to delete the directory after it has been created. Every time any directory is attempted to be removed with rmdir we get a

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

I am still having this weird problem with nodes hanging while I'm running OCFS. I'm using OCFS 1.0.9-12 and RHAS 2.1 I've been working on tracking it down and here's what I've got so far: 1. I create a file from node 0. This succeeds; I can /bin/cat the file, append, edit, or whatever. 2. From node 1, I do an operation that accesses the DirNode (e.g. /bin/ls) 3. Node 0

Anyone tracking svn for the last week or so has probably noticed the large number of changes happening to the code base. We're making some disk format changes, so people tracking ocfs2 will also have to closely track ocfs-tools trunk. Also, be prepared to have to reformat your file systems :) As far as what we're actually doing -- we're (finally!) fixing the directory layout issues

Hi... I have a strange problem with my Private NIC Channel, here is my environment details : 1. RHAS 2.1 with kernel 2.4.9-e.27 Enterprise 2. OCFS version : 2.4.9-e-enterprise-1.0.9-6 3. Oracle RDBMS : 9.2.0.4 RAC with 5 Nodes 4. Private NIC Channel: Broadcom BCM5700 My Private NIC channel is down intermittently, we just tracing the root of the problems by identify each product installed the

Greetings, Having read about the previous OSFS hangs, I think this one that we are seeing is different, but I'm not sure if this is caused by OCFS or the Linux OS. We are running OCFS Version 1.09 with Linux AS 3.0/9i RAC. We have a 2 node Intel Cluster (Node 1 and Node 2). This morning the DBA tried to do an "ls" command on /u06/oradata/database

Anyone have 15 minutes on a development installation of ocfs 1.0.9-12 to do me a favor? Follow these 8 steps and see if you have the same problem I'm having? It doesn't look to me like a hardware issue but if someone else does NOT have the same problem then I can rule ocfs out. 1. install ocfs-2.4.9-e-enterprise-1.0.9-12 and 1.0.9-12 tools 2. create a new filesystem node1# mkfs.ocfs -b

Here's a basic overview of the bug and a workaround for any DBA's or SysAdmin's reading this list. I'm sure that there will be an official fix soon, this is just an FYI if you run into the problem I had in the meantime. As soon as you install the updated ocfs-*.rpm the problem will go away. (You won't even need to fsck or anything... aren't they such nice guys?)

I know this isn't entirely OCFS related, but out of curiosity, but what experience have you had running RAC on RedHat or SuSE? I know Oracle supports both, but is one a better choice than the other? Seems to me like Oracle has been working more with RedHat. Does anyone know what Oracle mostly uses internally? What distro do you guys develop on? Would there be any drawbacks for choosing to

Haven't really tried this yet, but I'm wondering what the direction is for official ocfs support on SLES9. Anyone know if there are plans to support OCFS 1.x on sles9 at some point? I know it's a 2.6 kernel instead of 2.4... thanks, Jeremy This message (including any attachments) contains confidential information intended for a specific individual(s) and purpose, and is protected

what do you guys think about the best way to use DB_RECOVERY_FILE_DEST with ocfs? specifically, I'm wondering about archive logs... one thing i really like about using a flash recovery area it's space management features (after i copy my archivelogs to tape, it still keeps a copy around until it needs to reclaim the space) with ocfs v1 i've always wanted to give each node it's
