Subject: [PATCH 399/406] ganesha : allow refresh-config and volume
|
|
|
21ab4e |
export/unexport in failover state
|
|
|
21ab4e |
|
|
|
21ab4e |
If ganesha is not running on one of nodes in HA cluster, then all dbus
|
|
|
21ab4e |
commands send to that ganesha server will fail. This results in both
|
|
|
21ab4e |
refresh-config and volume export/unepxort failure. This change will
|
|
|
21ab4e |
gracefully handle those scenarios.
