ISSUE TYPE

• Bug Report

COMPONENT NAME

Volume / Disk Offering

CLOUDSTACK VERSION

4.17 RC2

OS / ENVIRONMENT

MS: CentOS 7 + Hypervisor: KVM + Storage: NFS, Local

SUMMARY

Change disk offering for the volume (attached to a running VM, from shared to local pool), with / without enabling "Auto migrate volume to another storage pool if required". The Offering of the volume is updated in both cases, and the volume remains in the same shared pool.

STEPS TO REPRODUCE

• Deploy a VM
• Create a DATA disk, say DATA01, with Shared Pool disk offering (or Shared Pool disk offering)
• Create a Local Pool disk offering, say LocalDisk (or Use any default Shared Pool disk offering)
• Change Disk Offering of the DATA disk (DATA01), to Local Pool disk offering LocalDisk (or Local Data disk to Shared Pool disk offering)

EXPECTED RESULTS

• The volume offering should change after migrating to local pool, when auto migrate is enabled. otherwise, fail with relevant error.
• The volume offering should not change, when auto migrate is disabled and should throw relevant error.

ACTUAL RESULTS

• The volume offering changes and volume remains in the same pool when auto migrate is enabled.
• The volume offering changes when auto migrate is disabled.
