gluster
Fedora: be more efficient for detecting brick mux setting
Previously, we were grep-ing through the output of gluster volume info
for the value of the cluster.brick-multiplex setting. But it is highly
inefficient to use gluster volume list to obtain a global setting.
With many volumes, this can take unnecessarily long. Furthermore, since
this is invoked right after the start of glusterd, glusterd may not be
done initializing.
This patch changes the retrieval of the brick multiplex setting
to use the command gluster volume get all cluster.brick-multiplex
which is exactly made for this purpose and won't get the whole list
of volumes.
@atinmu this should roughly be what we discussed on chat today. Please take a look!
@obnoxxx @atinmu one other thought here. Do we need to fetch current setting at all ? rather based on the user request go ahead and try it. Thoughts ?
