Re: How to Reorganise Storage Tags
when moving volume to new storage, when you want to change disk offering
(or compute offering for ROOT disk...), ACS doesn't allow that - it lists
only offerings that have same tag as current offering (not good...)
We have inhouse patch, so that you CAN do that, by making sure to list all
offergins that have TAG that matches the TAG of the new destination pool of
the volume (hope Im clear here).
All volumes read tag from their offering - so just either change
disk_offering_id filed for each moved/migrated volume to point to same
sized offering on new storage - and then normally change it once more via
UI to a new once etc - or manualy change to smaller disk offering (DB edit)
and later via UI/API to correct (same size) disk offering (or bigger if you
want to really resize)
I can try to share a patch in a non-developer, copy/paste way - in case you
want to patch your ACS to support this (as explained at the begining of the
Hope that helps
