quota: fix recording of last alert log message

2014-02-06T07:05:51+00:00

        Backport of http://review.gluster.org/6532

PROBLEM:

Alert log messages, corresponding to disk usage crossing soft-limit on a
directory, weren't being logged as often as expected.

CAUSE:

The mechanism in place to log alert messages, once every alert-time
seconds, set the previous logged time incorrectly.

FIX:

Update previous logged time only if we logged an alert message, ie. when
the "time was right" to alert.

mgmt/glusterd: make sure quota enforcer has established connection with quotad before marking quota as enabled.

2014-01-29T06:46:35+00:00

without this patch there is a window of time when quota is marked as
enabled in quota-enforcer, but connection to quotad wouldn't have been
established. Any checklimit done during this period can result in a
failed fop because of unavailability of quotad.

features/quota: Handle the corner case in statfs call

Problem: Even though limit is not set quota used to send 'quota-deem-statfs'
key in the dictionary resulting in incorrect calculations.

features/quota: maintain correct link_count in ancestry building

2014-01-28T16:49:30+00:00

codepath.

Ancestry building codepath can be executed simultaneously when a file
has hardlinks. So, following fixes are needed:

* modify local->link_count under locks in ancestry building codepath.
* before invoking check_limit on newly constructed parents,
  link_count should not be set, but instead incremented by as many
  number of new invocations of check_limit.
* decrementing link_count and the check whether the count has hit zero
  to resume the waiting call_stub should be atomic.

features/quota: remove in-memory accounting of files in enforcer

2014-01-28T16:47:26+00:00

Accounting was done in enforcer (though marker is the ultimate source
of truth) to offset cached directory size becoming stale. However,
with enforcer being moved to brick we can no longer maintain correct
cluster wide size for a directory. Hence removing accounting code from
enforcer.
