Subject: [PATCH 61/74] ganesha/scripts : remove dependency over export
|
|
|
a3470f |
configuration file for unexport
|
|
|
a3470f |
|
|
|
a3470f |
Currently unexport is performed by reading export id from volume configuration
|
|
|
a3470f |
file. So unexport has dependency over that file. This patch will unexport with
|
|
|
a3470f |
help of dbus command ShowExport. And it will only unexport the share which is
|
|
|
a3470f |
added via cli.
