Description Ganesh Kadam 2018-06-06 08:35:00 UTC

Description of problem:

Hi, 

One of our Cu is looking forward to do storage migration from CEPH to VMAX or VMAX to CEPH. Do we support it?

Version-Release number of selected component (if applicable):
RHOSP 10

Expected results:

nova retype from ceph to vmax and vmax to ceph is supported

Additional info:


Can we please confirm, if we do not support it, is there any target or specific date for the resolution of the bug?

Part of the issue is due to this upstream bug [1] ... and later on we hit this bug [2] when trying to attach the ceph/vmax volume to the instance in order to swap them.

This feature is not yet supported, but is an RFE targeted for OSP-15. It's also dependent on a new libvirt feature, per bug #1306562.
