Subject: [PATCH 063/124] glusterd/ganesha : update cache invalidation properly
|
|
|
74b1de |
during volume stop
|
|
|
74b1de |
|
|
|
74b1de |
As per current code, during volume stop for ganesha enabled volume the
|
|
|
74b1de |
feature.cache-invalidation was turned "off" in ganesha_manage_export().
|
|
|
74b1de |
And it never turn back to "on" when volume is started. It is not desire
|
|
|
74b1de |
to modify the volume options during stop, this patch fixes above mentioned
|
|
|
74b1de |
issue.
