There was a clear answer, WHY it did not worked on OCFSv2: - BerkleyDB and LDAP uses mmap to the files; - OCFSv2 don't implement it (because it is not possible to do such mapping in the cluster FS) - So they dont work on OCFSv2

Yes, but this EMC multipath software installs some kernelmodules (binaries, no sources) and they only match with the kernels in the list.
