Description Zhang Huan 2019-03-26 03:09:44 UTC
Description of problem:
Found a potential locking issue when reading code.

There are two cases to restart brick, one is when glusterd starts or quorum is met, another is when new peers are joined and quorum is changes. In the later case, sync_lock is not taken, and may cause lock corruption.
