Description Raghavendra Bhat 2011-09-29 06:20:31 EDT
created a distribute volume and started it. glustershd was not running. Then created a replicate volume and started. Found that glustershd was started.

Now I stopped the replicate volume. When I checked the gluster processes running, found that glustershd was still running inspite of no replicate volume running.

And when checked the glustershd volfile it had the distribute volumes graph in its volfile.

volume vol-client-0
    type protocol/client
    option remote-host hyperspace
    option remote-subvolume /mnt/sda7/export1
    option transport-type tcp

    type protocol/client
    option remote-host hyperspace
    option remote-subvolume /mnt/sda8/export1
    option transport-type tcp
end-volume

volume vol-replicate-0
    type cluster/replicate
    option background-self-heal-count 0
    option data-self-heal on
    option self-heal-daemon on
    subvolumes vol-client-0
