glusterd/shared_storage: Provide a volume set option to create and mount the shared storage
Introducing a global volume set option(cluster.enable-shared-storage) which helps create and set-up the shared storage meta volume. gluster volume set all cluster.enable-shared-storage enable On enabling this option, the system analyzes the number of peers in the cluster, which are currently connected, and chooses three such peers(including the node the command is issued from). From these peers a volume(gluster_shared_storage) is created. Depending on the number of peers available the volume is either a replica 3 volume(if there are 3 connected peers), or a replica 2 volume(if there are 2 connected peers). "/var/run/gluster/ss_brick" serves as the brick path on each node for the shared storage volume. We also mount the shared storage at "/var/run/gluster/shared_storage" on all the nodes in the cluster as part of enabling this option. If there is only one node in the cluster, or only one node is up then the command will fail Once the volume is created, and mounted the maintainance of the volume like adding-bricks, removing bricks etc., is expected to be the onus of the user. On disabling the option, we provide the user a warning, and on affirmation from the user we stop the shared storage volume, and unmount it from all the nodes in the cluster. gluster volume set all cluster.enable-shared-storage disable Change-Id: Idd92d67b93f444244f99ede9f634ef18d2945dbc BUG: 1222013 Signed-off-by: Avra Sengupta <asengupt@redhat.com> Reviewed-on: http://review.gluster.org/10793 Tested-by: Gluster Build System <jenkins@build.gluster.com> Tested-by: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Rajesh Joseph <rjoseph@redhat.com> Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com>
