Stan and I were chatting about the excess recovery notifications that we get from the current ODLM lock module. These happen with the current deadman lock design when a client (filesystem) mounts or unmounts on another node. Without going into detail ... I'm wondering if we can use the *lock value blocks* of the deadman locks to communicate whether: 1) A client has cleanly unmounted (no recovery needed) 2) A new client has mounted (no recovery needed after first-to-mount) 3) A node died (recovery needed) -- Ben -- Opinions are mine, not Intel's ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
