please don't run 10.3 packages on SLE10. They are compiled against
different libraries.

Please open a support incident with NTS.

It's safe, but probably a performance penalty.

SLE10-SP1 _is_ updated to 1.2.4 already. The kernel-of-the-day has all
the recent fixes.
However, I'm not perfectly sure whether reexporting OCFS2 via NFS(v3 or
v4?) is already working perfectly. I would not be surprised if it
doesn't yet. For sure, file locking doesn't work (yet).

Lars
