My seach-fu is failing me. I seem to recall a discussion about OST mounts being sequentialized, even if the mount commands are issued in parallel. Perhaps something about a superblock lock being to blame. Does any one recall that discussion? Is there a bug open on this? Was there any resolution? Chris
