cluster/replicate: Modify command in unit file to assign port correctly

2019-06-08T05:39:10+00:00

Problem:
In unit file of TA process we have been using ta-vol as
volume id and also ta-vol-server.transport.socket.listen-port=24007

In volume file for TA process we only consider volname
as "ta" and not as "ta-vol". That's why it was not able to assign
this port number to ta process as in volume file it will try to
find server xlator as ta-vol

volume ta-server  <<<<<<<<< not ta-vol-server
 46     type protocol/server
 47     option transport.listen-backlog 10
 48     option transport.socket.keepalive-count 9
 49     option transport.socket.keepalive-interval 2
 50     option transport.socket.keepalive-time 20
 51     option transport.tcp-user-timeout 0
 52     option transport.socket.keepalive 1
 53     option auth.addr./mnt/thin-arbiter.allow *
 54     option auth-path /mnt/thin-arbiter
 55     option transport.address-family inet
 56     option transport-type tcp
 57     subvolumes ta-io-stats
 58 end-volume

Solution:
Provide "ta" as vol id for the  command which Unit file
is going to execute.

Also, made changes in setup-thin-arbiter.sh to correctly
identify the directory of Unit file irrespective of the location from
where we are executing this script.

rpm: add thin-arbiter package

2019-03-11T04:05:34+00:00

Discussion on thin arbiter volume -
https://github.com/gluster/glusterfs/issues/352#issuecomment-350981148

Main idea of having this rpm package is to deploy thin-arbiter
without glusterd and other commands on a node, and all we need
on that tie-breaker node is to run a single glusterfs command.
Also note that, no other glusterfs installation needs
thin-arbiter.so.

Make sure RPM contains sample vol file, which can work by default,
and a script to configure that volfile, along with translator image.

thin-arbiter : Provide scripts and service file to start thin-arbiter process

2018-05-30T03:24:49+00:00

1 - setup-thin-arbiter.sh
To setup directory path for thin-arbiter. This is the path where replica id
file will be placed and used by TA process.
By default it will be /mnt/thin-arbiter. It is better to use default path
and once set it should not be changed.

2 - gluster-ta-volume.service
This is the Unit file used by systemd to start and keep the thin-arbiter
process running.

3 - thin-arbiter.vol
This is the default volume file for thin-arbiter. It will be used to start
thin-arbiter process. This should not be modified by user except the
directory path which can be modified using [1].
