Subject: [PATCH 309/309] geo-rep: Fix config upgrade on non-participating node
|
|
|
14f8ab |
|
|
|
14f8ab |
After upgrade, if the config files are of old format, it
|
|
|
14f8ab |
gets migrated to new format. Monitor process migrates it.
|
|
|
14f8ab |
Since monitor doesn't run on nodes where bricks are not
|
|
|
14f8ab |
hosted, it doesn't get migrated there. So this patch fixes
|
|
|
14f8ab |
the config upgrade on nodes which doesn't host bricks.
|
|
|
14f8ab |
This happens during config either on get/set/reset.
