Rebuild boot / OS drive
-
I stupidly assumed that the HP servers I built two of my XCP boxes on would allow me to move the single boot drive to RAID1 without any data loss. Sadly, I assumed badly.
So, to get the XCP boot disk into a fault-tolerant RAID1 state, I'll have to destroy the boot disk and rebuild the OS.
The VM's are on separate disks, so I'm not worried about them very much - they should be just fine, provided I don't do something stupid while rebuilding the boot disks. (I'll have backup of the VM's too, just in case.)
So, what's the best way to go about getting things back up?
-
Obviously I'll have to handle all the steps to get it onto RAID1, and XCP booting up again. That's "easy".
-
But then I need to "reimport" all the meta-data for the VM's so the system knows their names, locations, etc. (I have an XOA meta-data backup occurring too, but I'd assume there's a way we don't have to use that, right?)
Is there an article on this somewhere? (I'd assume this is largely covered for a disaster recovery situation, so there must be some coverage somewhere... Even an "upgrade" does something similar, I think, when it backs up the "old" system before running the upgrade..)
TIA

Have you check the documentation? https://xen-orchestra.com/docs/metadata_backup.html#performing-a-restore

So, that's the "best" way? Backup the meta-data with XOA, rebuild the OS drive - add the "new" server into XOA and restore the meta-data back to the new install?(I'm not doubting it is, just wanting to be sure we're understanding each other fully.)
Seems straight-forward - but there's a ton of things I've done over the years that "seemed" pretty straight-forward that turned out to be anything but, and at least occasionally found I had no way back.
