Subject: [PATCH 289/305] changelog: fix br-state-check.t failure for brick_mux
|
|
|
a3470f |
|
|
|
a3470f |
Problem: Sometime br-state-check.t crash while runnning
|
|
|
a3470f |
for brick multiplex and command in test case is
|
|
|
a3470f |
taking 2 minutes for detach a brick
|
|
|
a3470f |
|
|
|
a3470f |
Solution: Update code in changelog xlator specific to wait
|
|
|
a3470f |
on all connection before cleanup rpc threads and
|
|
|
a3470f |
cleanup rpc object only in non brick mux scenario
