Subject: [PATCH 478/478] DHT - Fixing rebalance failure on issuing stop
|
|
command
|
|
|
|
Issuing a stop command for an ongoing rebalance process results in an error.
|
|
This issue was brought up in https://bugzilla.redhat.com/1286171 and a patch
|
|
(https://review.gluster.org/24103/) was submitted to resolve the issue.
|
|
|
|
However the submitted patch resolved only part of the
|
|
problem by reducing the number of log messages that were printed (since
|
|
rebalnace is currently a recursive process, an error message was printed
|
|
for every directory) but didn't fully resolve the root cause for the
|
|
failure.
|
|
|
|
This patch fixes the issue by modifying the code-path which handles the
|
|
termination of the rebalance process by issuing a stop command.
