feature/bitrot: Ondemand scrub option for bitrot

2016-08-25T21:39:38+00:00

The bitrot scrubber takes 'hourly/daily/biweekly/monthly'
as the values for 'scrub-frequency'. There is no way
to schedule the scrubbing when the admin wants it.

Ondemand scrubbing brings in the new option 'ondemand'
with which the admin can start scrubbing ondemand.
It starts the scrubbing immediately.

Ondemand scrubbing is successful only if the scrubber
is in 'Active (Idle)' (waiting for it's next frequency
cycle to start scrubbing). It is not entertained when
the scrubber is in 'Paused' or already running.

Here is the command line syntax.

gluster volume bitrot  scrub ondemand

build: do not #include "config.h" in each file

2015-05-29T12:43:17+00:00

Instead of including config.h in each file, and have the additional
config.h included from the compiler commandline (-include option).

When a .c file tests for a certain #define, and config.h was not
included, incorrect assumtions were made. With this change, it can not
happen again.

bitrot: Volfile generation should not proceed if node doesn't have any brick.

2015-05-10T05:25:15+00:00

glusterd crashes when bitrot is enabled on a distributed volume from a node
which doesn't host a brick.

While generating volfile glusterd should check number of brick on that node. If
node doesn't have any brick then graph generation for bitrot and scrubber should
not proceed further.

features/bitrot: Per volume bitrot translator

2015-05-04T05:17:17+00:00

Currently whatever bitrot/scrubber tunable value user set for one
volume that value is considering for all other volumes also.
Each volume should act on their respective bitrot/scrubber tunable
value.

For handling bitrot/scrubber tunable value independently with respect
to all the volume bitrot and scrubber translator should run seperatly
for each volume.
