systemd/glusterfssharedstorage : remove dependency for var-run-gluster-shared_storage

2017-07-17T11:41:00+00:00

Currently the script used by glusterfssharedstorage have dependency over
var-run-gluster-shared_storage. But this service will be present only if
node has rebooted. Also in reboot scenario , there is a chance that this
service can be executed before creating var-run-gluster-shared_storage.
In that case glusterfssharedstorage will get succeed even without mounting
the shared storage

Also the type of glusterfssharedstorage changed to "forking" so that it can
be active(instead of dead) after the successful start.

glusterd.service (systemd), shows "Active failed" when gd in stop state

2017-06-19T16:06:01+00:00

While doing cleanupandexit glusterd was handling the signal SIGTERM which
is clean exit but systemd treats it as failure being a non-zero value.

With this fix dependency "SuccessExitStatus " has been added
in glusterd.service which takes care of service stop properly.

eventsapi: Add Init scripts for different distributions

2016-09-09T10:29:33+00:00

Added init scripts for
- SysvInit(CentOS 6 or Red Hat 6)
- rc.d (FreeBSD)

Most of the latest distributions are using systemd. Support to be
added for other distributions which are not using systemd.

Removed systemctl wrapper functions(start/stop/status) from
gluster-eventsapi CLI(peer_eventsapi.py). Status and Reload
re-implemented using pid file check.

Added pid file support for glustereventsd.

Following dependencies removed
python-flask - Only used for example dashboard. User can install
if required.
python-fasteners - Not available for EPEL 6, added custom code using
fcntl as replacement.

packaging/eventsapi: Make Python site-packages variable global

2016-08-29T07:28:30+00:00

Python site-packages path is assigned when glupy is enabled.
Eventsapi will not work as expected if glupy is disabled using
./configure --disable-glupy.

With this patch, all the Python variables are moved out of glupy
and used inside it.

systemd services will fail if we import gluster.cliutils python library
which is installed in /usr/local/lib/python.2.7/site-packages or some
other location. With this patch, Environment variable is added in
systemd service file.

build: systemd unit should not be marked executable

2016-08-08T01:05:05+00:00

systemd complains about the unit for GlusterD when it is executable:

  Configuration file /usr/lib/systemd/system/glusterd.service is marked executable. Please remove executable permission bits. Proceeding anyway.

The Makefile that installs the unit has some scripted commands. These
are not needed and standard "*dir" and "*DATA" postfixes for variables
can be used instead.

The EXTRA_DIST variable is needed for building the 'make dist' tarball
on systems where there is no systemd. The unit would be missing from the
tarball if it is not explicitly included.

eventsapi: Gluster Eventing Feature implementation

2016-07-18T20:52:20+00:00

[Depends on http://review.gluster.org/14627]

Design is available in `glusterfs-specs`, A change from the design
is support of webhook instead of Websockets as discussed in the design

http://review.gluster.org/13115

Since Websocket support depends on REST APIs, I will add Websocket support
once REST APIs patch gets merged

Usage:
Run following command to start/stop Eventsapi server in all Peers,
which will collect the notifications from any Gluster daemon and emits
to configured client.

    gluster-eventsapi start|stop|restart|reload

Status of running services can be checked using,

    gluster-eventsapi status

Events listener is a HTTP(S) server which listens to events emited by
the Gluster. Create a HTTP Server to listen on POST and register that
URL using,

    gluster-eventsapi webhook-add  [--bearer-token ]

For example, if HTTP Server running in `http://192.168.122.188:9000`
then add that URL using,

    gluster-eventsapi webhook-add http://192.168.122.188:9000

If it expects a Token then specify it using `--bearer-token` or `-t`

We can also test Webhook if all peer nodes can send message or not
using,

    gluster-eventsapi webhook-test  [--bearer-token ]

Configurations can be viewed/updated using,

    gluster-eventsapi config-get [--name]
    gluster-eventsapi config-set  
    gluster-eventsapi config-reset 

If any one peer node was down during config-set/reset or webhook
modifications, Run sync command from good node when a peer node comes
back. Automatic update is not yet implemented.

    gluster-eventsapi sync

Basic Events Client(HTTP Server) is included with the code, Start
running the client with required port and start listening to the
events.

    /usr/share/glusterfs/scripts/eventsdash.py --port 8080

Default port is 9000, if no port is specified, once it started running
then configure gluster-eventsapi to send events to that client.

Eventsapi Client can be outside of the Cluster, it can be run event on
Windows. But only requirement is the client URL should be accessible
by all peer nodes.(Or ngrok(https://ngrok.com) like tools can be used)

Events implemented with this patch,
- Volume Create
- Volume Start
- Volume Stop
- Volume Delete
- Peer Attach
- Peer Detach

It is easy to add/support more events, since it touches Gluster cmd
code and to avoid merge conflicts I will add support for more events
once this patch merges.

glusterd.service: Ensure rpcbind is started before glusterd

2015-11-18T10:21:05+00:00

Having the rpcbind.service under the `After` option only ensures that
glusterd.service is started after rpcbind.service if both are
enabled/started at the same time. It doesn't ensure that starting
glusterd.service will start rpcbind.service.

The systemd.unit(5) man page suggests to use both the `Requires` and
`After` options to ensure that rpcbind is started before glusterd,
whenever glusterd is started.

2015-09-15T13:08:38+00:00

Issue: glusterd was not running in debug mode, this is because of
"systemctrl start glusterd" was not reading configuration from glusterd-sysconfig file.

Fix: Set glusterd-sysconfig file as "EnvironmentFile"  and pass args to glusterd.
