We have a test 10gR2 RAC cluster using ocfs2 filesystems for the Clusterware files and the Database files. We need to increase the node slots to accomodate new RAC nodes. Is it true that we will need to umount these filesystems for the upgrade (i.e. Database and Clusterware also)? We are planning to use the following command format to perform the node slot increase: # tunefs.ocfs2 ?N 3

Hi everybody, My problem is that I want to add a new node to an existing RAC with ocfs2, without stop the database. If I add a new node to an existing ocfs cluster, do I need to stop the ocfs in the others nodes of the cluster? I've tried to do it without stop the ocfs in the others nodes but I get the following error:

I'm using ocfs2 and all modules from Suse (SLES9), no self compilations. Here are the details: * 32-bit machine (writing to ocfs2 partition/LUN and where the corruption was reported): Kernel: 2.6.5-7.257-bigsmp #1 SMP i686 i386 GNU/Linux OCFS2 rpms: ocfs2console-1.2.1-4.2 ocfs2-tools-1.2.1-4.2 o2cb_ctl -V: o2cb_ctl version 1.2.1 /etc/init.d/o2cb status: Module "configfs":

On RHEL4 also, the service o2cb starts later than _netdev device mounts. So mount fails. Should the o2cb service start earlier to fix this?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Folks, When I installed ocfs2 the first time and setup oracle to work with it, the clustername defaulted to "ocfs2". We are testing adding new nodes, but we would like to add new nodes to the o2cb cluster in a different clustername. Do I need to do anything to keep that separate on the filesystem. I just want to make sure that when

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 list, today, I installed a two node Oracle 10g RAC system on SLES9 SP2 RC2 which shares (via a SAN) a database volume and a quorum (ocr and voting). This volumes are formated with ocfs2 - so far no problem. At the moment I'm stuck with the mounting of these volumes at boot time. The user-guide of ocfs2-tools mentions to add the corresponding lines to fstab - but at the time when fstab

We just installed a new cluster with 6 HP DL380g5, dual single port Qlogic 24xx HBAs connected via two HP 4/16 Storageworks switches to a 3Par S400. We are using the 3Par recommended config for the Qlogic driver and device-mapper-multipath giving us 4 paths to the SAN. We do see some SCSI errors where DM-MP is failing a path after get a 0x2000 error from the SAN controller, but the path gets puts

Hi, I have installed and configured ocfs2 as per the given guidelines on two nodes. The output of the service status of o2cb and ocfs2 is as under: Node: rashida1 -------------------------------------------------- [root at rashida1 ~]# service o2cb status Driver for "configfs": Loaded Filesystem "configfs": Mounted Driver for "ocfs2_dlmfs": Loaded Filesystem

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, I might be overlooking the obvious, but I have yet to find "/etc/init.d/o2cb" however, I read that configuration uses this init script. Where is it? From: ocfs2-tools-1.2.4/README.O2CB [Starting the OCFS2 Clustering Services] O2CB is comprised of a simple node manager, heartbeat, TCP protocol, and DLM. The basic steps in startup are as follows: 1) Load the nodemanager,

Hi everyone; I have a problem on my 10 nodes cluster with ocfs2 1.2.9 and the OS is RHEL 4.7 AS. 9 nodes can start o2cb service and mount san disks on startup however one node can not do that. My cluster configuration is : node: ip_port = 7777 ip_address = 192.168.5.1 number = 0 name = fa01 cluster = ocfs2 node: ip_port =

RHEL 4 (CENT OS) Am I waisting my time trying to get the 10G Clusterware installer to use OCFS2 volumes for the voting and OCR disks ? The ocfs2 setup seems happy on both nodes but the 10G installer says the location entered for the oracle cluster registry (OCR) is not shared across all the nodes in the cluster Do the volumes need to mounted ? I did with no change . [root@green rc5.d]#

hello, I'm running Ubuntu Breezy with the OCFS2 modules in the standard kernel. I installed ocfs2console and ocfs2-tools I've formatted a partition with ocfs2. But I can't add any node or mount the device(with the ocfs2console). because I get a "Unable to access cluster service" I can't find the cause nor the solution to this. root@lenaeja:~# /etc/init.d/o2cb status

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, another problem I did not find a solution for... I ran "o2cb configure" and configured a cluster named "ocfs2". Lazy me, I did not invent a new name. Now this cluster must be renamed to avoid confusion, the name has to change to "sapcluster". I changed /etc/ocfs2/cluster.conf to the new name and ran

I looked around, found older post which seems not applicable anymore. I have a cluster of 2 nodes right now, which has 3 OCFS2 file systems. All the file systems were formatted with 4 node slots. I added the two news nodes (by hand, by ocfs2console and o2cb_ctl), so my /etc/ofcfs/cluster.conf looks right: node: ip_port = 7777 ip_address = 192.168.201.1 number = 0

We're trying to setup 3 PRDM partitions (VMware) across 2 nodes. As long as only one is configured in cluster.conf, there's not problem. As soon as we try to use 2 or more we get issues. It looks the same as bug 636: http://oss.oracle.com/bugzilla/show_bug.cgi?id=636 I posted my cluster.conf and command line results there. I'm including them here in the hopes that someone on this
