glusterd/thin-arbiter: Thin-arbiter integration with GD1
gluster volume create <VOLNAME> replica 2 thin-arbiter 1 <host1>:<brick1> <host2>:<brick2>
<thin-arbiter-host>:<path-to-store-replica-id-file> [force]
The changes have been made in a way that the last brick in the bricks list
will be treated as the thin-arbiter.
GD1 will be manipulated to consider replica count to be as 2 and continue creating the
volume like any other replica 2 volume but since thin-arbiter volumes need ta-brick
client xlator entries for each subvolume in fuse volfile, volfile generation is
modified in a way to inject these entries seperately in the volfile for every subvolume.
Few more additions -
1- Save the volinfo with new fields ta_bricks list and thin_arbiter_count.
2- Introduce a new option client.ta-brick-port to add remote-port to ta-brick xlator entry
in fuse volfiles. The option can be set using the following CLI syntax -
gluster volume set <VOLNAME> client.ta-brick-port <PORTNO.>
3- Volume Info will contain a Thin-Arbiter-path entry to distinguish
from other replicate volumes.
