tier: port value missing on cli parsing

2017-05-31T11:39:20+00:00

problem: as tier didn't have a port all the values regarding
the port were removed. but the cli needs a port value to parse and
print the status.

fix: fake the port value with a zero.

libglusterfs, gfdb, glusterfs: Add missing breaks

2017-02-26T16:29:26+00:00

A few switches did not have breaks causing fall throughs. Most of them
have been fixed with fall through comments for those that are
intentional.

Tier: remove warning related to the enum

2017-02-07T05:12:29+00:00

PROBLEM: In the tier as a service patch the enums for tier (from
gf1_op_command and gf_defrag_command) are put into a single enum
gf_defrag_command which causes a warning that will make the build
fail.

FIX: send both the enum and eliminate the warning.

tier : Tier as a service

2017-01-17T04:49:47+00:00

tierd is implemented by separating from rebalance process.

The commands affected:

1) Attach tier will trigger this process instead of old one
2) tier start and tier start force will also trigger this process.
3) volume status [tier] will show tier daemon as a process instead
of task and normal tier status and tier detach status works.
4) tier stop implemented.
5) detach tier implemented separately along with new detach tier
status
6) volume tier volname status will work using the changes.
7) volume set works

This patch has separated the tier translator from the legacy
DHT rebalance code. It now sends the RPCs from the CLI
to glusterd separate to the DHT rebalance code.
The daemon is now a service, similar to the snapshot daemon,
and can be viewed using the volume status command.

The code for the validation and commit phase are the same
as the earlier tier validation code in DHT rebalance.

The “brickop” phase has been changed so that the status
command can use this framework.

The service management framework is now used.
DHT rebalance does not use this framework.

This service framework takes care of :

*) spawning the daemon, killing it and other such processes.
*) volume set options , which are written on the volfile.
*) restart and reconfigure functions. Restart is to restart
the daemon at two points
        1)after gluster goes down and comes up.
        2) to stop detach tier.
*) reconfigure is used to make immediate volfile changes.
By doing this, we don’t restart the daemon.
it has the code to rewrite the volfile for topological
changes too (which comes into place during add and remove brick).

With this patch the log, pid, and volfile are separated
and put into respective directories.
