similar to: RAC on OCFS2

Folks, When a node crashes OCFS2 tends to hang for a while fencing the node off the cluster, is there a way to test whether OCFS2 is ready to resume operations, I am trying to restart a service on a different box and I keep getting errors and I would like to isolate the fact that the filesystem is not ready from the inability to restart the service on a different box. thank you, Enrique Sanchez.

Hello folks, I have a Filesystem that went R/O in one node but not in the second here is the output of the following command on the node with the R/O issue: fsck.ocfs2 -fn /dev/dm-23 Checking OCFS2 filesystem in /dev/dm-23: label: oraCRSMeta uuid: 71 df 25 70 8b 34 43 f8 a4 e7 cd 2c c5 66 84 27 number of blocks: 2209680 bytes per block: 4096

I have been a user of OCFS2 for quite some time now (2 years or so) and a user of Oracle RAC for several years as well. My usage of these two is completely independent though, the cluster filesystem is for application level usage (web servers, etc.) only because RAC can manage its own shared storage directly. And that brings me to my observation/question... I keep seeing a lot of messages

Is the order important when installing ocfs2 and Oracle RAC? If you have an existing RAC installation and you want to use ocfs2 for shared files but not for the OCR or Voting Disks, do you need to reinstall the Oracle Clusterware after installing OCFS2?

Hi, I'm setting up a 2-node Oracle 9i RAC on OCFS2. But I have some problems with understanding how the shared Oracle_Home is being used. For instance there is the *$ORACLE_HOME/oracm/admin/cmcfg.ora* file. The $ORACLE_HOME is on the SAN so the 2 nodes have access to this file. How will the settings then be done per node? Is there a guide/tutorial/howto for installing Oracle 9i RAC on

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Folks, We would like to evaluate how ocfs2 will work with a debian distribution. Most of our systems people favor debian and so we are evaluating whether debian and ocfs2 work nicely + oracle 10gR2 rac. I know that debian is not supported by Oracle, but this is only for testing. Has anyone had experience with this? If so can you provide

Hi to all: I''m trying to build an Oracle Rac10gR2 under 2 xenitized RedHat 4 nodes ( The host domain is debian 3.1 ) Well, all goes well until time to mount ocfs2. For Rac10gR2 I need to mount ocfs2 partitions with the datavolume option, but latests versions of ocfs2 doesn''t comes with this option ( you can enable the O_DIRECT feature directly in the init.ora file, with the

Hey folks, I've been getting requests from the users that they want the OCFS2 filesystems aligned to 64k boundaries, however, when I began the project, the dummy of me, created the OCFS2 filesystem on top of the whole disk device (no partition) for example, one of the SAN devices would show up as /dev/dm-10, I created the filesystem using the following command: mkfs.ocfs2 -L SOMELABEL

I think I might have miss understood where it is failing, has this file been added to the DB on the web site or does it fail when you try to onfigure this?

When using OCFS2 in a Oracle RAC set, one would configure OCFS2 to use the private interconnect address ( in cluster.conf). Are there any known issues / reasons not to have the private interconnect set up for jumbo frames when using in conjunction with OCFS2 ?

Hi All I just installed a 2 node ,10 r2 rac on centos Linux 4.6 My rac install was done by following Jeff Hunters document (excellent work!) http://www.idevelopment.info/ For storage I used openfiler with the iscsi protocol http://www.openfiler.com/ everything went perfect... to the letter, I gracefully shutdown the 2 nodes , then the openfiler appliance, when I went to start it back up,

Hello ocfs2 experts, OS is RHEL 2.6.9-78.0.13.ELsmp x86 With OCFS2 1.2.9 RDBMS/Clusterware s/w 10.2.0.1 Hoping someone can help me resolve the following error when running cluvfy to check ocfs2-shared storage. Have validated that the devices were correctly mounted and cross-referenced with another 2-node RAC environment we have where we'd successfully run cluvfy on prior to installing

I have tryied change the disk bus to SCSI, add a SCSI controller whose model is virtio-scsi, still can't setup the RAC instance. I tried to use windows 2008 Failover Cluster feature to setup a a Failover Cluster instead, and I can't find any cluster disk to share between two nodes. So when Failover Cluster is setup, I can't add any Cluster disk to the Failover Cluster. Have I missed

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
