When I try and run the mkfs.ocfs2 command after I have updated all of the other nodes in the cluster with the new node information in cluster.conf I am getting the following error: mkfs.ocfs2 -b 4k -C 32K -L "ocfs2" -N 4 /dev/sdb1 mkfs.ocfs2 1.4.4 Cluster stack: classic o2cb Overwriting existing ocfs2 partition. mkfs.ocfs2: Could not create domain while initializing the dlm As this is

We upgraded our production database cluster (6 node) from EL4 Update 5 to EL5 Update 5, including upgrading OCFS2 from 1.2.9 to 1.4.4. We are now noticing slowdown of batch jobs in Oracle, while hotbackup runs faster. One thing we saw is that journal mode changed from write-back to ordered, as we don't specify journal mode during mount. Oracle sees this as slowdown based on higher IO latency,

Hi, according to cluster file system logic and from my testing experience on other FS, the more nodes add into clustered file system, the more performance degradation it will have, two questions: 1. Is it possible to tune ocfs2 so that the performance issue wouldn't be a breakdown problem? 2. How many cluster nodes do you guys experience will have major performance issue? The fs we use is 90%
