Hello,
Please review the plan I've wrote for the migration.
MUST REQUIREMENTS
* Gluster data domain
there are issues with snapshots/thin provisioning on gluster storage
domain currently.
so consider posix.
also, are the nodes both gluster and virt or separate?
if the same, there is an issue with gluster replication and libvirt live
migration ports.
* Export domain
* Open a ticket to rackspace regarding static MAC address mapping
STEPS
1. Install rackspace03.ovirt.org
2. Create gluster based DC and add gluser storage as data domain.
3. Add rackspace03.ovirt.org into the DC.
4. Create export domain.
5. Attach export domain into rackspace[01/02].ovirt.org.
6. Poweoff all VMs on rackspace[01/02].ovirt.org and export them.
7. Attach export domain to the gluster based dc
8. Import all vms
9. Poweroff vms and check their statuses/connectivity. In jenkins as well.
10. Add rackspace[01/02].ovirt.org to the gluster based dc
11. Do steps 5-10 for rackspace02
Will remove the local DCs a week after migration after we will be sure that everything is
ok.
