How to set/visualize volume options

Observed behavior

the volume options used in glusterd do not appear to have the same name in glusterd2, i couldn't visualize them either. Example options:
performance.readdir-ahead: on
diagnostics.client-log-level: WARNING
...

Expected/desired behavior

glustercli volume set volname performance.readdir-ahead on
and the option is set

glustercli volume info volname
and some options are displayed

glustercli volume set volumename TAB completion of the option

glustercli options list
to retrieve all the options

Details on how to reproduce (minimal and precise)

curl -i -X GET http://localhost:24007/v1/volumes/test01/options
returns empty if no options exist

glustercli volume set test01 performance.io-thread-count 32
Volume option set failed
Error: Request failed with HTTP Status code 500
Transaction step vol-option.Validate failed on peer 7a6c5914-3b72-49f6-9bf8-018e90c7d5c7 with error: Validation failed for volume option: option not found: performance.io-thread-count

Information about the environment:

• Glusterd2 version used (e.g. v4.1.0 or master): {"glusterd-version":"v4.1.0-0","api-version":1}

• Operating system used: centos 7.5.1804

• Glusterd2 compiled from sources, as a package (rpm/deb), or container: from repo: https://buildlogs.centos.org/centos/7/storage/x86_64/gluster-4.1/

• Using External ETCD: (yes/no, if yes ETCD version): no

• If container, which container image:

• Using kubernetes, openshift, or direct install:

• If kubernetes/openshift, is gluster running inside kubernetes/openshift or outside:

Other useful information

• glusterd2 config files from all nodes (default /etc/glusterd2/glusterd2.toml)
• glusterd2 log files from all nodes (default /var/log/glusterd2/glusterd2.log)
  the other thing is that there is nothing related to API calls in /var/log/glusterd2/glusterd2.log
• ETCD configuration
• Contents of uuid.toml from all nodes (default /var/lib/glusterd2/uuid.toml)
• Output of statedump from any one of the node

Useful commands

• To get glusterd2 version

  glusterd2 --version
  

• To get ETCD version

  etcd --version
  

• To get output of statedump

  curl http://glusterd2-IP:glusterd2-Port/statedump

Yes, currently GD2 uses a different way of setting the xlator options but #816 will address this issue. But in case you are using -

curl -XPOST http://localhost:24007/v1/volumes/test01/options
to set volume options, you will need to use the option names that GD2 support which you can refer to by hitting -

curl -XGET http://localhost:24007/v1/volumes/test01/options

curl -i -X GET http://localhost:24007/v1/volumes/test01/options

I am not entirely sure why you get an empty response to the above request as there are some xlator options that are set by default which should be returned as an output.

glustercli volume set test01 performance.io-thread-count 32

Please try something like -
glustercli volume set io-threads.thread-count 32 --advanced

In case, I have missed out on something or you have any other issue please do notify.

hi @vpandey-RH i have successfully added the option you suggested however the GET command still returning empty as '405 Method Not Allowed':

[root@gluster1 ~]# glustercli volume set test01 io-threads.thread-count 32 --advanced

@labazza Can you update your GD2 to the latest version - v4.1.0-152.git353e236 and try the above request again.

[Madhu-1]

@kshlm can we get updated glusterd2 from this repo
am not sure how this repo gets updated https://buildlogs.centos.org/centos/7/storage/x86_64/gluster-4.1/

[kshlm]

@labazza The version of GD2 you're using (v4.1.0) does not support getting just the options from ReST (GET /v1/volumes/volume/options). This was introduced in a later commit.
glustercli volume info displays the options because the volume info API returns the full volinfo which contains all set options.

If you want to, you can try out the nightly rpms which have the Get options API available. Please note that GD2 is still under heavy development, and the official builds available via the distro repositories will not always be up-to-date.

@labazza did you get a chance to test the latest nightly?

I have moved to glusterd, and been busy with that deployment. I will setup glusterd2 on a VM and continue testing. If you want this can be archived.

thanks
