* added log message when server fails to send the reply frameAmar Tumballi2009-08-171-4/+8
| | | | | | | | | | | | | As of now, if a frame submit fails on server, there are no logs, and clients will have missing frames (which leads to 'hangs'). Supporting situation like this very tricky without proper log messages. As a step to make our log message lean and meaningful, this log is important. Signed-off-by: Anand V.

* protocol/client: fixed registration of saved_fdsAnand Avati2009-08-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | In client_open_cbk, client_opendir_cbk the list_add_tail macros were invoked with wrong ordered arguments, causing the existing registered fd list to get unlinked from the saved_fds list. The effects of this is far fetched - when transport disconnects, open fds are no more marked bad as they are not reachable from the saved_fds list. After reconnection, resumed access on this fd causes reference to invalid fds on the server. It could appear in the form of 'unresolved fd' error, readdir happening on a file fd, files reading from other files, etc. Signed-off-by: Anand V.

* Add a random initial offset to the afr round robin indexErick Tryzelaar2009-07-161-0/+3
| | | | | | | | | | | | | | | This patch helps to distribute load across an afr cluster when you have clients with the same access patterns, such as in benchmarking or map-reduce. By randomly offsetting the initial read_child_rr, clients should distribute reads over the afr nodes on average. A better solution could be to randomly shuffle the children instead of chosing a different initial offset. This should average the reads better across the nodes, but I'm not sure if there are any other consequences to doing this. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
