Tier/cli: detach status xml output

2017-05-30T13:37:09+00:00

Problem: detach status xml output was broken because
of the wrong argument. The status_op sent to verify
whether it is a tier status command was as false.

Fix: the argument being passed was changed from false
to true.

Tier: Watermark check for hi and low value being equal

2017-05-12T19:58:26+00:00

        back-port of : https://review.gluster.org/17175

Problem: Both low and hi watermark can be set to same value
as the check missed the case for being equal.

Fix: Add the check to both the hi and low values being equal
along with the low value being higher than hi value.

TIER/TESTS: improving regression test for tier

2017-05-10T06:29:01+00:00

The test files that were marked as bad test were checked and
updated for centos. The tests that had issue were fixed.
Tests that aren't needed anymore are removed.

REASON:

tests/basic/tier/tier-file-create.t
This test checks one line after creating a tiered volume (which
is done in every tier test). So this line is moved along with
other test in tier and the file is deleted.

tests/bugs/tier/bug-1286974.t
This bug checks for the tier as a task and tier has been moved
from a task to service as a part of the tier as a service patch
https://review.gluster.org/#/c/13365/
So it is removed from bad tests.

tests/basic/tier/record-metadata-heat.t
This test had a bug and has been fixed.

tests/basic/tier/bug-1214222-directories_missing_after_attach_tier.t
tests/basic/tier/fops-during-migration.t
tests/basic/tier/tier-snapshot.t
tests/basic/tier/tier_lookup_heal.t

These test seem to work fine on centos now.

CLI/TIER: removing old tier commands under rebalance

2017-02-07T14:28:39+00:00

        back-port of : https://review.gluster.org/#/c/16463/

PROBLEM: gluster v rebalance  tier start works even after
the switch of tier to service framework.
This lets the user have two tierd for the same volume.

FIX: checking for each process will make the new code hard
to maintain. So we are removing the support for old commands.

core: run many bricks within one glusterfsd process

2017-02-02T00:54:58+00:00

This patch adds support for multiple brick translator stacks running in
a single brick server process.  This reduces our per-brick memory usage
by approximately 3x, and our appetite for TCP ports even more.  It also
creates potential to avoid process/thread thrashing, and to improve QoS
by scheduling more carefully across the bricks, but realizing that
potential will require further work.

Multiplexing is controlled by the "cluster.brick-multiplex" global
option.  By default it's off, and bricks are started in separate
processes as before.  If multiplexing is enabled, then *compatible*
bricks (mostly those with the same transport options) will be started in
the same process.

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.

tier/cli : printing a warning instead of skipping the node

2016-05-20T14:25:37+00:00

Problem: skipping the status of the nodes down creates confusion
to the user as one might see the status as completed for all nodes
and while performing detach commit, the operation will fail as the
node is down

Fix: Display a warning message

Note: When the last node is down (as per the peer list) then
warning message can't be displayed as the total number of peers
participating in the transaction is considered to be the total count.

2016-05-05T14:45:54+00:00

Problem: during a volume restart or tier start force, the
value of tier status is set as started irrespective of the result.

Fix: The appropriate value of status is set during the restart of

Tier: tier command fails message when any node is down

PROBLEM: the dict doesn't get set on the node if its down.
so while printing the output on cli we get a ENOENT
which ends in a tier command failed.

FIX: this patch skips the node that wasn't available
and carrys on with the next node for both tier status
and tier detach status.

tier/dht : Attach tier fix layout to run in background

2016-03-28T16:17:59+00:00

1. Spawn a thread for background fix-layout for tier process.

2. Once the fix-layout is completed a marker xttr is set on the root of
volume to mark the completion of the background fixlayout, so that
even if the tier process is spawned again, fixlayout will not be
issued, if it was completed last time.

3. Please note that promotion of legacy files will happen eventually as
the ctr lookup heal in the fixlayout slowly heals the ctr db for legacy
files OR the ctr lookup heal happend due to a name lookup.

4. When a detach tier is successful in evacuation data from hot tier, we remove
the marker xattr is removed. So that next attach tier runs the background
tier fixlayout.

what is remaining ?
1. Instead of clearing the marker xattr of tiering fix layout at the end of detach start
clear it during detach commit. But the issue is detach commit is a glusterd operation
and the volume is not mounted in glusterd.
The reason we want to do it in detach commit is that if the admin wants to attach the
same tier again, then a background fixlayout will be triggered, which would not be needed.
2. Clearing the CTR DB of the cold bricks when there is a detach commit, as it will be having
entries which will be stale when the volume is used, with ctr off (ctr is switched off only when
we have detach commit.)
