orthogonally, I upgraded a node to FC6, with the latest update kernel
2.6.19-1.2895.fc6. now I can't mount the ocfs2 fs on that very node anymore:

(2917,0):o2net_check_handshake:1093 node rack1 (num 1) at
10.0.2.21:7777advertised net protocol version 2 but 4 is required,
disconnecting
(2917,0):o2net_check_handshake:1093 node rack4 (num 6) at

but I CAN mount a second ocfs2 partition, when this very node is the first
to mount it.

seems like there has been some upgrade to the OCFS protocol, which is not
backward compatible, is it???
