Hi, We have three RHEL4 servers with ocfs-1.2.4 installed. Now I want to upgrade both RedHat and ocfs2 in this way: <on all nodes> Reinstall with RHEL5 Install ocfs2-1.2.9 Reinstall oracle with clusterware and submit to the Oracle cluster </on all nodes> <on all nodes> Upgrade ocfs2 from 1.2.9 to 1.4.7 </on all nodes> I have reinstalled one of the servers with RHEL5 and then tried different things because I wasn't shure of how to do this. Ended up with the list above. The things I've done is: Installed rpm packages for ocfs2-1.4.4 Deinstalled rpm packages for ocfs2-1.4.4 Downloaded, built and installed source packages for ocfs2-1.4.7 Installed rpm packages for ocfs2-1.4.7 (without deinstall of the selfbuild source of ocfs2-1.4.7, don't know how) Deinstalled rpm packages for ocfs2-1.4.7 Downloaded, built and installed source packages for ocfs2-1.2.9 In the end I was able to mount the ocfs2 disks. So I moved on installing all needed Oracle software, including clusterware. When trying to start the Oracle CRS, the server rebooted and kept rebooting until I was able to disable Oracle CRS automatic start. Today I tried to create a file on one of the ocfs2 filesystem: # echo mktest>/disk07/mktest.txt This worked well, and then I tried to delete it: # rm /disk07/mktest.txt Then I lost connection and a "kernel panic" error was displayed on the console screen. Now I'm wondering what could be wrong? Could it be that the selfbuild source installation of ocfs2-1.4.7 isn't overwritten/deleted and causing this problem? Does anybody know how to deinstall this? Any suggestions what to do? I've tried to post this message twice before, but it didn't show up. Is it because I attached a wordpad-file with a screendump of the "kernel panic". If so, how can I attach a file and which files isn't stopped by a filter? Regards Morten K

OK, so my plan of upgrading both RH and ocfs2 is not possible? Like this: <on all nodes> Reinstall RHEL5 (latest kernel) Install ocfs2-1.2.9 Reinstall oracle with clusterware and submit to the Oracle cluster </on all nodes> <on all nodes> Upgrade ocfs2 from 1.2.9 to 1.4.7 </on all nodes> Is it because ocfs2 1.2 is only provided for all el5 kernels upto u3, the reason of my problems when trying to compile and run it on kernel 2.6.18-194.el5? Ocfs2 1.2 is not supposed to work on kernel 2.6.18-194.el5? So my reinstall plan should be: < on one node> Reinstall RHEL5 (latest kernel) Install ocfs2-1.4.7 Reinstall oracle with clusterware and submit to the Oracle cluster </on one node> Stop oracle cluster on all nodes Unmount all ocfs2 disks Stop ocfs2 on all nodes <on reinstalled node> Start ocfs2 Mount ocfs2 disks Start oracle cluster </on reinstalled node> <on rest of the nodes> Reinstall RHEL5 (latest kernel) Install ocfs2-1.4.7 Reinstall oracle with clusterware and submit to the Oracle cluster Start ocfs2 Mount ocfs2 disks Start oracle cluster </on rest of the nodes> This plan will need to be done in a quiet period of the system, otherwise the running node will have to much pressure on it.

Or, you could upgrade one node from rhel4 to rhel5 u3 and install ocfs2 1.2.9. That node could then be brought online. Repeat the process until all nodes are on rhel5 u3. Then shutdown the entire cluster and upgrade all nodes to 1.4.7. Bring them back online. The last step would be to upgrade the nodes, one by one, from u3 to u5.
