Subject: [PATCH 291/305] Core: The lock contention on
|

gf_client_dump_inodes_to_dict

Problem: For a distributed replicated volume, in the inode status
|
|
|
d1681e |
command the lock on gf_client_dump_inodes_to_dict is held by the
|
|
|
d1681e |
first brickop. while this is being processed, if the second brickop
|
|
|
d1681e |
comes. It fails to get the lock and the whole brick op fails.
|
|
|
d1681e |
|
|
|
d1681e |
Fix: Instead of using a TRY_LOCK which errors out if the lock is busy,
|
|
|
d1681e |
Use LOCK which will wait till the lock is acquired.
