We get a fault callback on _every_ tcp connection fault. Normally, we want to reopen the connection when that happens. If the address we have is bad, however, and connection attempts always result in a connection refused or similar error, explicitly closing and reopening the msgr connection just prevents the messenger's backoff logic from kicking in. The result can be a console full of [ 3974.417106] ceph: osd11 10.3.14.138:6800 connection failed [ 3974.423295] ceph: osd11 10.3.14.138:6800 connection failed [ 3974.429709] ceph: osd11 10.3.14.138:6800 connection failed Instead, if we get a fault, and have outstanding requests, but the osd address hasn't changed and the connection never successfully connected in the first place, do nothing to the osd connection. The messenger layer will back off and retry periodically, because we never connected and thus the lossy bit is not set. Instead, touch each request's r_stamp so that handle_timeout can tell the request is still alive and kicking. Signed-off-by: Sage Weil <sage@newdream.net> |
