cli: error out incomplete CLI commands

2017-07-31T17:29:29+00:00

cli_cmd_bricks_parse () & cli_cmd_volume_remove_brick_parse () were not
handling the the error cases where the command is incomplete with
missing brick details which could lead to glusterd crashes.

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

2017-05-10T18:58:21+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.

Fixes quota aux mount failure

2017-05-08T06:15:55+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: (storhaug) remove ganesha

2017-03-21T17:13:44+00:00

remove all vestiges of ganesha

The storhaug CLI is used to manage ganesha and Samba. Also any setup
and teardown of the ganesha HA is initiated using storhaug to preserve
the proper layering.

CLI/TIER: removing old tier commands under rebalance

2017-02-07T06:36:27+00:00

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.

cli: keep 'gluster volume status detail' consistent

2017-01-19T23:52:26+00:00

The output of the command 'gluster volume status  detail' is
not consistent between operating systems. On linux hosts it shows the
file system type, the device name, mount options and inode size of each
brick. However the same command executed on a FreeBSD host doesn't show
all this information, even for bricks stored on a linux.

Additionally, for hosts other than linux, this information is shown as
'N/A' many times. This has been fixed to show as much information as it
can be retrieved from the operating system.

The file contrib/mount/mntent.c has been mostly rewriten because it
contained many errors that caused mount information to not be retrieved
on some operating systems.

glusterd : Introduce reset brick

2016-08-30T02:55:53+00:00

The command basically allows replace brick with src and
dst bricks as same.

Usage:
gluster v reset-brick   start
This command kills the brick to be reset. Once this command is run,
admin can do other manual operations that they need to do,
like configuring some options for the brick. Once this is done,
resetting the brick can be continued with the following options.

gluster v reset-brick    commit {force}

Does the job of resetting the brick. 'force' option should be used
when the brick already contains volinfo id.

Problem: On doing a disk-replacement of a brick in a replicate volume
the following 2 scenarios may occur :

a) there is a chance that reads are served from this replaced-disk brick,
which leads to empty reads. b) potential data loss if next writes succeed
only on replaced brick, and heal is done to other bricks from this one.

Solution: After disk-replacement, make sure that reset-brick command is
run for that brick so that pending markers are set for the brick and it
is not chosen as source for reads and heal. But, as of now replace-brick
for the same brick-path is not allowed. In order to fix the above
mentioned problem, same brick-path replace-brick is needed.
With this patch reset-brick commit {force} will be allowed even when
source and destination  are identical as long as
1) destination brick is not alive
2) source and destination brick have the same brick uuid and path.
Also, the destination brick after replace-brick will use the same port
as the source brick.

glusterd/cli: cli to get local state representation from glusterd

2016-08-26T15:23:37+00:00

Currently there is no existing CLI that can be used to get the
local state representation of the cluster as maintained in glusterd
in a readable as well as parseable format.

The CLI added has the following usage:

 # gluster get-state [daemon] [odir ] [file ]

This would dump data points that reflect the local state
representation of the cluster as maintained in glusterd (no other
daemons are supported as of now) to a file inside the specified
output directory. The default output directory and filename is
/var/run/gluster and glusterd_state_ respectively. The
option for specifying the daemon name leaves room to add support for
other daemons in the future. Following are the data points captured
as of now to represent the state from the local glusterd pov:

 * Peer:
    - Primary hostname
    - uuid
    - state
    - connection status
    - List of hostnames

 * Volumes:
    - name, id, transport type, status
    - counts: bricks, snap, subvol, stripe, arbiter, disperse,
 redundancy
    - snapd status
    - quorum status
    - tiering related information
    - rebalance status
    - replace bricks status
    - snapshots

 * Bricks:
    - Path, hostname (for all bricks these info will be shown)
    - port, rdma port, status, mount options, filesystem type and
signed in status for bricks running locally.

 * Services:
    - name, online status for initialised services

 * Others:
    - Base port, last allocated port
    - op-version
    - MYUUID
