[Ocfs2-users] OCFS2 and berkeley database files

Tue Dec 5 16:04:47 PST 2006

It is IMHO not a good idea (not needed, less reliable, much slower) to cluster LDAP servers like that. Just use a local file system on each server and use replication.

You are on a very old release of OCFS2. The OCFS2 homepage and FAQ both list a SLES9 kernel version newer than the one you are using.

But that may not be the reason for the error. My bet is that bdb is attempting to create a shared writeable mmap that ocfs2 1.2 does not support.
