Description Xavi Hernandez 2018-09-13 14:14:44 UTC
Description of problem:

Bricks don't detect abrupt client disconnections in a reasonable time. If this happens when the dead client had locks held, accessing the locked file from other clients will take a huge amount of time.

REVIEW: https://review.gluster.org/21170 (socket: set 42 as default tpc-user-timeout) posted (#2) for review on master by Xavi Hernandez

Comment 2 Worker Ant 2018-09-14 05:38:08 UTC
COMMIT: https://review.gluster.org/21170 committed in master by "Raghavendra G" <rgowdapp> with a commit message- socket: set 42 as default tpc-user-timeout

The 'tcp-user-timeout' option is define in the 'socket' module, but it's
configured in 'protocol/server' and 'protocol/client', which are the
parents of the 'socket' module.

However, current options management logic only takes into consideration
default values specified in the 'socket' module itself, ignoring values
defined in the owner xlator.

This patch simply sets the default value of tcp-user-timeout in the
'socket' module so that server and client use the expected value.
