This belongs on the ocfs2-users@oss.oracle.com mailing list. The short answer is that LVM is not cluster-safe, so you would have to create an LVM configuration that makes no changes online. What do I mean? A RAID-5 setup modifies data outside the block being written, and so is not cluster safe. A setup that swaps in a hot-spare device is not safe. About the only thing that could work is a concatenation of disks, and you cannot change it while ocfs2 is mounted. You can try the clutsered LVM (CLVM), but that uses a different cluster technology than ocfs2 does, and as such the two cluster stacks may conflict when a node goes down. There are plans to make ocfs2 better work with CLVM in the future. Joel -- Life's Little Instruction Book #407 "Every once in a while, take the scenic route."
