Description Tom Llewelyn 2017-05-11 09:39:18 UTC 
Created attachment 1277807 [details]
Dumps of various commands (customer info redacted)

Description of problem:

After successfully deploying gluster + heketi using cns-deploy, the heketi-cli command run from one of the OCP masters is able to access read only commands (e.g. heketi-cli topology info) but write commands (e.g. heketi-cli volume create --size=10) fail with an empty error string


Version-Release number of selected component (if applicable):

Heketi Image: rhgs3/rhgs-volmanager-rhel7:3.2.0-10
Heketi Client: heketi-client-4.0.0-9.el7rhgs.x86_64


How reproducible:


Steps to Reproduce:
1. Set up Cluster Native Storage using cns-deploy according to the installation guide:

https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.2/html/container-native_storage_for_openshift_container_platform/

2. Run heketi-cli commands against the published route on OCP

Actual results:

heketi-cli topology info  - returns the topology
heketi-cli volume list - returns a list of volumes
heketi-cli volume create --size=10 - returns "Error:"

Expected results:

heketi-cli volume create --size=10 - should return info on created volume

Additional info:

Connecting directly to the heketi pod using oc rsh and then running the volume create command with server set to localhost:8080 the command works and creates the volume.
Comment 3 Tom Llewelyn 2017-05-12 14:05:15 UTC 
Turns out this behaviour is due to a trailing / in the HEKETI_CLI_SERVER setting.

If you have a trailing / then GET commands succeed but POST commands fail.

Some meaningful debug output would be helpful here though

Thanks
