Storage decommissioning
Hi guys,
I'm writing just to ask for advice...
We're decommissionig our storage and we need to move all the VMs from old
storage to this new one.
In CS we've defined a new primary storage and I think we've to migrate all
ROOT and DATA disks from old PRIMARY to the new PRIMARY, this should be
done without interruption of the service.
The new storage will host also SECONDARY storage, so we need to move also
Template, Snapshots and other things.
How can we do it?
Thank you!!

Hi Alessandro,
moving ROOT and DATA volumes should be no problem and can be done via webinterface. Some hypervisor can do this even without downtime. What hypervisor do you use?
Moving your secondary storage is difficult, because there is now automation as far as I know. But we are not using the latest version of CS.
Can you move the IP of secondary storage to the new storage? If so the I would do:
1. rsync all files
2. stop management service
3. wait and be sure all task of CS are finished
4. do one more rsync
5. shutdown old storage
6. configure same IP on new storage
7. start Management service
Mit freundlichen Grüßen / With kind regards,
Swen

Hi,
what do you mean? XenServer is taking care of the metadata backup if you enabled it. As far as I know XenServer will update the metadata.
Mit freundlichen Grüßen / With kind regards,

Ok guys... we're about to finish the migration of primary storage... but I've a question.
Since we've moved all the Instance's volume (ROOT and DATA) through ACS (4.5), should we consider anything about VMs metadata?
We're running XS 6.2 SP1.
Moving the volume will move also metadata?
Regards.

You do not need to move them. If you put the primary storage they are located into maintenance than CS will recreate VRs and System VMs on another primary storage.
This will include a short downtime for each VR, but CS will do this step by step; VR after VR....

Hi,
Decommissioning of primary storage should not be a problem. Since we can migrate all the disks to additional primary storage in the cluster.
Coming to artifacts stored in the secondary storage, if we make the templates as public, all the templates will be available in additional secondary storages within the zone. For snapshots and volumes may have to rsync and change the image_store id in all the relevant db tables.
