Subject: [PATCH 093/124] glusterd: Change op-version of cache-invalidation in |
|
quick-read |
|
|
|
In upstream cache-invalidation option in quick read was introduced with |
|
4.0. There are two problems with it: |
|
|
|
1. The key being made duplicate to md-cache xlator, so setting the same |
|
option actually enables this feature on both md-cache and quick-read. |
|
2. As the op-version tagged to this key was GD_OP_VERSION_4_0_0, with a RHGS |
|
3.5 cluster when a md-cache profile is set to a particular volume old |
|
client fails to mount which is wrong. |
|
|
|
Solving 1 with out breaking backward compatibility in upstream is quite hard. |
|
This patch addresses both the problems in downstream by (a) changing the |
|
op-version to GD_OP_VERSION_6_0_0 and (b) renaming this key to |
|
quick-read-cache-invalidation. The fix is currently made downstream only till a |
|
proper solution is identified in upstream. |
