geo-rep: Support for using Volinfo from Conf file

2018-01-23T03:03:01+00:00

Once Geo-replication is started, it runs Gluster commands to get Volume
info from Master and Slave. With this patch, Georep can get Volume info
from Conf file if `--use-gconf-volinfo` argument is specified to monitor

Create a config(Or add to the config if exists) with following fields

    [vars]
    master-bricks=NODEID:HOSTNAME:PATH,..
    slave-bricks=NODEID:HOSTNAME,..
    master-volume-id=
    slave-volume-id=
    master-replica-count=
    master-disperse_count=

Note: Exising Geo-replication is not affected since this is activated
only when `--use-gconf-volinfo` is passed while spawning `gsyncd
monitor`

Tiering support is not yet added since Tiering + Glusterd2 is still
under discussion.

protocol/server: Fix "auth-path" in options table

2018-01-22T11:19:16+00:00

Options set will crash the brick with glusterd2.
glusterd used to set "auth-path" during volfile
generation. With glusterd2, it should come from
options table.

libgfapi: Add new api for supporting mandatory-locks

2018-01-22T09:54:02+00:00

The current API for byte-range locks [glfs_posix_lock()] doesn't
allow applications to specify whether it is advisory or mandatory
type locks. This particular change is to introduce an extended
byte-range lock API with an additional argument for including
the byte-range lock mode to be one among advisory(default) or
mandatory. Patch also includes a gfapi test case which make use
of this new api to acquire mandatory locks.

geo-rep: Improve geo-rep pre-validation logs

2018-01-22T06:33:48+00:00

Geo-rep runs gverify.sh which does pre-validation.
As part of it, master and slave volume is mounted
to verify the size. If for some reason, the mount
fails, the error message does not point out the
mount log file location. Also both master and
slave mount logs are same.

Patch does following improvements.

1. Master and slave mount logs are separated and
   error message points the log file to be looked for.
2. The log location is changed to /var/log/glusterfs/geo-replication
   instead of /var/log/glusterfs/geo-replication-slaves
3. The log file name is changed to "gverify-mastermnt.log" and
   "gverify-slavemnt.log" for master and slave mount respectively
