quota/glusterd: enhance quota enable and disable process

2016-04-29T10:11:35+00:00

Previously quota crawl was done from the single mount point,
this is very slow process if there are huge number of files exists
in the volume

This RFE will now spawn crawl process for each brick in the
volume, and  files are looked in parallel independently for each
brick. This improves the speed of crawling process for
entire files-system

This patch also fixes below problem
* Previously, mountdir was created under '/tmp'.
  If someone tries to cleanup '/tmp'/ directory
  then it is very dangerous that we loose volume data
  So create a mount point under /var/run/gluster/tmp
  instead

* Previously, file-system crawl is performed from all the nodes,
  which is a redundant operation and performance will degrade
  The problem is fixed with this patch

glusterd: use string comparison for realpath checks in glusterd_is_brickpath_available

2016-02-29T11:55:23+00:00

glusterd_is_brickpath_available () used to call realpath() for checking the
whether the new brick path matches with the existing ones. The problem with this
is if the underlying file system is bad for any one of the existing bricks then
realpath() would fail and we wouldn't allow to create the new brick even if it
should be allowed.

Fix is to use string comparison with having a new field real_path in brickinfo
to store the absolute path

glusterd: set decommission_is_in_progress flag for inprogress remove-brick op on glusterd restart

2016-02-23T05:42:31+00:00

While remove brick is in progress, if glusterd is restarted since decommission
flag is not persisted in the store the same value is not retained back resulting
in glusterd not blocking remove brick commit when rebalance is already in
progress.

During reblance restart after glusterd restarted, we are not

Tier: "tier start force" command implementation

2015-12-23T00:24:11+00:00

The start command doesnt restart the tier deamon if the deamon
is running at one node. hence to bring up the tierd on the nodes
where the deamon is down, the force command is implemented.
It skips the check for tierd running.

glusterd: cli command implementation for bitrot scrub status

2015-11-20T03:41:43+00:00

CLI command  for bitrot scrub status will be :

gluster volume bitrot  scrub status

Above command will show the statistics of bitrot scrubber.

Upon execution of this command it will show some common
scrubber tunable value of volume  followed by
statistics of scrubber statistics of individual nodes.

sample ouput for single node:

Volume name : 

State of scrub: Active

Scrub frequency: biweekly

Bitrot error log location: /var/log/glusterfs/bitd.log

Scrubber error log location: /var/log/glusterfs/scrub.log

=========================================================

Node name:

Number of Scrubbed files:

Number of Unsigned files:

Last completed scrub time:

Duration of last scrub:

Error count:

=========================================================

This is just infrastructure. list of bad file, last scrub
time, error count value will be taken care by
http://review.gluster.org/#/c/12503/  and
http://review.gluster.org/#/c/12654/ patches.

glusterd: move new feature (tiering) enum op to the last of the array

2015-11-04T04:10:28+00:00

Currently new feature tiering have GD_OP_DETACH_TIER and GD_OP_TIER_MIGRATE
enum in the middle of the glusterd_op_ enum array. In multi nodes
cluster when one of the node upgraded from lower version to higher
version and upon executing command can end up in a mismatch in enum ops
at the receiver ends causing command execution fail.

Fix is to put every new feature glusterd operation enum code to last of
the enum array.
