You might start with this: "Why are LVM2 commands, such as vgscan, taking a very long time to complete?" http://kbase.redhat.com/faq/docs/DOC-5542 although I am not sure why RHEL 5.3 would be any different than RHEL 5.2. Also see the dm-multipath release note discussed here: https://bugzilla.redhat.com/show_bug.cgi?id=460301#c9 (A modification to /etc/udev/rules.d/40-multipath.rules.) We have tried the workaround suggested in 5.3 release notes already - it didn't help. Sorry, I forgot to mention in the initial defect report. The original problem was seen with 2GB of memory. The problem did not happen when we increased the memory to 10GB (and then we iteratively found out that the problem does not happen with 6GB or more memory). Please test with RHEL 5.4 GA and the forthcoming 5.5 Beta. Is there still a problem when using 5.5? Closing because of no activity. If there still is a problem, reopen the bug and report evidence. |
