Incorrect/Inconsistent provisioning type displayed on 3PAR for FULL provisioned volume #712

Closed sonawane-shashikant closed 5 years ago

sonawane-shashikant commented 5 years ago

Summary: Incorrect/inconsistent provisioning type displayed on 3par for volume created through docker cli with provisioning type as full.

OS: Centos 7.6

3PAR IP: 10.50.3.9 3par OS: 3.3.1 (MU4)

pre-requisite: Docker should be installed and etcd should be up and running

Steps to reproduce:

  1. Installed and enable HPE 3par plugin.
  2. create full provisioning volume on 3PAR using 3PAR CLI
  3. create full provisioning volume on docker using docker cli.
  4. verify provisioning type for both the volume on 3par using shovv command.

Expected: Provisioning type should be displayed as "full" for both the volumes.

Actual result: provisioning type has been shown as "cpvv" instead of "full" for volume created using docker CLI.

Note: As per HPE 3PAR OS Command Line Interface <HPE 3PAR OS 3.3.1 MU1> The "-type cpvv" option is deprecated and will be removed in a subsequent release.

output:

Full provision volume created on 3PAR

CSIM-8K02_MXN6072AC7 cli% createvv jupyter vol_3par 20g

Full provision volume created on docker:

[root@cld6b10 ~]# docker volume create -d hpe --name vol_docker -o provisioning="full" vol_docker

Needs investigation from wsapi

bhagyashree-sarawate commented 5 years ago

When we create the volume using docker plugin commands we have the provisioning type as FULL as per the wsapi document. As per WSAPI document , FULL - 1 FPVV, either with no snapshot space or with statically allocated snapshot space. Also, a commonly-provisioned VV where the user space is fully provisioned and the snapshot space is associated with the snapCPG property.

Provision type is shown as 1 for both full and cpvv provision type volume as per wsapi document, so this seems to be invalid issue for Docker plugin.

Created volume using full provisioning and verified wsapi output which always give provisioningType=1. Output
