geo-replication: gverify should use disk_size and available_size

2014-02-06T15:31:23+00:00

"commit ef4bb42382a5c9c3ca0907136669a659c2a20311" was incomplete since
reduction in sizes doesn't really have any affect on the problem when
disks sizes are similar.

Actual fix is to verify disk_size and then verify available_size

geo-rep: Fix no error when slave size less than master size

2014-01-23T17:41:10+00:00

in df command output, default block-size is 1K, but BUFFER_SIZE is
in bytes, so verify will succeed even if slave size is less than
master size.

Added -B1 to df command(that is --block-size=1) to get all values in
bytes.

glusterd/cli changes for distributed geo-rep

2013-07-26T20:19:18+00:00

Commands:
gluster system:: execute gsec_create
gluster volume geo-rep   create [push-pem] [force]
gluster volume geo-rep   start [force]
gluster volume geo-rep   stop [force]
gluster volume geo-rep   delete
gluster volume geo-rep   config
gluster volume geo-rep   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
