tier: port value missing on cli parsing

2017-05-31T17:51:32+00:00

problem: as tier didn't have a port all the values regarding
the port were removed. but the cli needs a port value to parse and
print the status.

fix: fake the port value with a zero.

glusterd: Eliminate race in brick compatibility checking stage

2017-05-31T15:06:58+00:00

In https://review.gluster.org/17307/, while looking for compatible
bricks for multiplexing, it is checked if the brick pidfile exists
before checking if the corresponding brick process is running.

However checking if the brick process is running just after
checking if the pidfile exists isn't enough since there might be
race conditions where the pidfile has been created but hasn't
been updated with a pid value yet. This commit solves that by
making sure that we wait iteratively till the pid value is updated
as well.

Fixes upgrade issue in quota.conf

2017-05-31T05:58:24+00:00

When an op-version bump up is done the glusterd_store_quota_config
upgrades the quota conf file, although overwriting the same later
which leaves out all gfid entries. While this is warranted for
enable opcode, for upgrade we need to retain gfids. So for upgrade
opcode, we return once the upgrade is done.

glusterd: Don't spawn new glusterfsds on node reboot with brick-mux

2017-05-30T13:36:40+00:00

With brick multiplexing enabled, upon a node reboot new bricks were
not being attached to the first spawned brick process even though
there wasn't any compatibility issues.

The reason for this is that upon glusterd restart after a node
reboot, since brick services aren't running, glusterd starts the
bricks in a "no-wait" mode. So after a brick process is spawned for
the first brick, there isn't enough time for the corresponding pid
file to get populated with a value before the compatibilty check is
made for the next brick.

This commit solves this by iteratively waiting for the pidfile to be
populated in the brick compatibility comparison stage before checking
if the brick process is alive.

glusterd: ignore incorrect uuid validation if uuid_str is empty

2017-05-30T13:35:38+00:00

If uuid_str is not filled up in dictionary (when glusterd bit is old),
we shouldn't be additional validation with peer uuid otherwise the
handshake request will fail.

Fixes quota aux mount failure

2017-05-13T21:12:07+00:00

The aux mount is created on the first limit/remove_limit/list command
and it remains until volume is stopped / deleted / (quota is disabled)
, where we do a lazy unmount. If the process is uncleanly terminated,
then the mount entry remains and we get (Transport disconnected) error
on subsequent attempts to run quota list/limit-usage/remove commands.

Second issue, There is also a risk of inadvertent rm -rf on the
/var/run/gluster causing data loss for the user. Ideally, /var/run is
a temp path for application use and should not cause any data loss to
persistent storage.

Solution:
1) unmount the aux mount after each use.
2) clean stale mount before mounting, if any.

One caveat with doing mount/unmount on each command is that we cannot
use same mount point for both list and limit commands.
The reason for this is that list command needs mount to be accessible
in cli after response from glusterd, So it could be unmounted by a
limit command if executed in parallel (had we used same mount point)
Hence we use separate mount points for list and limit commands.

glusterd: Make reset-brick work correctly if brick-mux is on

2017-05-12T19:59:02+00:00

Reset brick currently kills of the corresponding brick process.
However, with brick multiplexing enabled, stopping the brick
process would render all bricks attached to it unavailable. To
handle this correctly, we need to make sure that the brick process
is terminated only if brick-multiplexing is disabled. Otherwise,
we should send the GLUSTERD_BRICK_TERMINATE rpc to the respective
brick process to detach the brick that is to be reset.
