Good afternoon all, We are upgrading our storage backbone, moving it off of our common 1 GBit backbone to a 10 dedicated storage backbone. When this happens, we will need to re-ip the storage domains with to IP address of the 10 GBit release. For a period of time, as we upgrade the rest of our hardware, we may have to operate both the original and the new IP addresses. *Some gotchas:* 1. My controller is at level 4.3, but some of my my compute nodes are at level 4.2 because they have older Penryn class processors. We didn't plan the upgrade - it happened because our controller's hard drive failed and took the cluster with it. *Practical question:* 1. Can I simply operate the same storage domain on two IP addresses on different physical networks eg. 10.10.1.x and 10.10.10.x ? 2. Is an alternative solution to operate two storage domains from the storage appliance, and migrate the storage from the 1GBit domain to the 10 GBit domain over time, then drop/abandon the old storage domain once everything is on the 10 GBit? I have plenty of storage to do this. 3. Is there a better way I haven't thought of?

Hi David, Are you using Gluster/NFS or iSCSI/CEPH ? Best Regards, Strahil Nikolov
Hi Strahil, My backing store is NFS backed by FreeNAS.

Hi David,

Best Regards, Strahil Nikolov
Hi David, I would recommend you to create an identical NFS export which you can use as a storage domain. Also check if FreeNAS supports copy-offload , which will allow the migration of the VM's disks to happen on the FreeNAS (from 1 folder to another) instead through the NFS client (oVirt Hypervisors).
