glusterd/cli changes for distributed geo-rep
Commands: gluster system:: execute gsec_create gluster volume geo-rep <master> <slave-url> create [push-pem] [force] gluster volume geo-rep <master> <slave-url> start [force] gluster volume geo-rep <master> <slave-url> stop [force] gluster volume geo-rep <master> <slave-url> delete gluster volume geo-rep <master> <slave-url> config gluster volume geo-rep <master> <slave-url> status The geo-replication is distributed. The session will be created, and gsyncd will be spawned on all relevant nodes, instead of only one node. geo-rep: Collecting status detail related data Added persistent store for saving information about TotalFilesSynced, TotalSyncTime, TotalBytesSynced Changes in the status information in socket: Existing(Ex): FilesSynced=2;BytesSynced=2507;Uptime=00:26:01; New(Ex): FilesSynced=2;BytesSynced=2507;Uptime=00:26:01;SyncTime=0.69978; TotalSyncTime=2.890044;TotalFilesSynced=6;TotalBytesSynced=143640; Persistent details stored in /var/lib/glusterd/geo-replication/${mastervol}/${eSlave}-detail.status Change-Id: I1db7fc13ffca2e415c05200b0109b1254067f111 BUG: 847839 Original Author: Avra Sengupta <asengupt@redhat.com> Original Author: Venky Shankar <vshankar@redhat.com> Original Author: Aravinda VK <avishwan@redhat.com> Original Author: Amar Tumballi <amarts@redhat.com> Original Author: Csaba Henk <csaba@redhat.com> Signed-off-by: Avra Sengupta <asengupt@redhat.com> Reviewed-on: http://review.gluster.org/5132 Reviewed-by: Vijay Bellur <vbellur@redhat.com> Tested-by: Vijay Bellur <vbellur@redhat.com>
