Hi, I'm currently looking for ways to backup my disks.
Live storage migration converted my disks from
preallocated to thin provisioning. Preallocated disk
backups are working from a simple dd from a snapshot,
but the thin qcow2 disks are a problem. I seems it uses
multiple logical volumes (3 in my case).
For one snapshot? Are you sure?
Not anymore, i've deleted the host and its disks :(
Also they
are combined MUCH bigger than the preallocated:
8GB raw vs thin: 31 GB - 1 snapshot.
What version are you using?
And on what storage?
3.3 on iscsi. And I am talking about the LVM lv sizes. No idea how much
of that space the qcow actually occupies.
So I have two questions:
- how would you backup these thin disks?
You could just copy all three of your volumes.
A more robust way, though, would probably be to export the disk to an
export domain.
The problem was, that i didn't know WHICH volumes to copy, but that was
probably due a wrong sql query.
