Subject: [PATCH 214/221] geo-rep: Upgrading config file to new version
|
|
|
14f8ab |
|
|
|
14f8ab |
- configuration handling is enhanced with patch
|
|
|
14f8ab |
https://review.gluster.org/#/c/glusterfs/+/18257/
|
|
|
14f8ab |
- hence, the old configurations are not applied when
|
|
|
14f8ab |
Geo-rep session is created in the old version and upgraded.
|
|
|
14f8ab |
|
|
|

This patch solves the issue. It,
|
|
|
14f8ab |
- checks if the config file is old.
|
|
|
14f8ab |
- parses required values from old config file and stores in new
|
|
|
14f8ab |
config file, which ensures that configurations are applied on
|
|
|
14f8ab |
upgrade.
|
|
|
14f8ab |
- stores old config file as backup.
|
|
|
14f8ab |
- handles changes in options introduced in
