tests/basic: Prevent mount-options.t from being run.

2014-02-06T04:07:56+00:00

mount-options.t introduces a race leading to failures in
regression tests. Hence disabling the test unit till we
sort out the race.

Also removing the workaround introduced in mount.t.

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

2014-01-25T17:10:12+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/compress: rename "compress" option to "network.compression"

2014-01-24T09:27:12+00:00

Prevent mistaking the "compress" options for storage (at rest)
compression. The cdc-xlator is implemented to support compressing of
network traffic (READ and WRITE FOPs).

features/quota: Improvements to quota

2013-11-26T18:24:02+00:00

* Two stages of quota enforcement is done:

  Soft and hard quota Upon reaching soft quota limit on the directory
  it logs/alerts in the quota daemon log (ie DEFAULT_LOG_DIR/quotad.log)
  and no more writes allowed after hard
  quota limit. After reaching the soft-limit the daemon alerts the
  user/admin repeatively for every 'alert-time', which is
  configurable.

* Quota enforcer is moved to server-side.

  It  takes care of enforcing quota. Since enforcer doesn't have the
  cluster view, it relies on another service called
  quota-aggregator. Aggregator, on query can return the size of a
  directory based on the cluster view.

  Enforcer is always loaded in the server graph and is by passed if
  the feature is not enabled.

  Options specific to enforcer:

  server-quota - Specifies whether the feature is on/off. It is used
  to by pass the quota if turned off.

  deem-statfs - If set to on, it takes quota limits into consideration
  while estimating fs size. (df command). The algorithm followed is,
  i.   Adjust statvfs based on limit configured on root.
  ii.  If limit is set on the inode passed, use size/limits on that inode to
       populate statvfs. Otherwise, use size/limits configured on root.
  iii. Upon statvfs, update the ctx->size on the inode.
  iv.  Don't let DHT aggregate, instead take the maximum of the usages from the
       subvols of the DHT, since each of it contains the complete information.

  Enforcer also makes use of gfid-to-path conversion functionality to
  work correctly when a client like nfs predominently relies on
  nameless lookups.

* Quota Aggregator acts as a thin client to provide cluster view

  Its a lightweight *gluster client* process with no mount point,
  started upon enabling quota or restarting the volume. This is a
  single process run on each brick, which can answer queries on all
  volumes in the cluster. Its volfile stored in
  GLUSTERD_DEFAULT_WORKING_DIR/quotad/quotad.vol.
