Hi Marian,
I'm trying to do it with thin snapshots now. It's all very confusing, and I can't get it to work.
I've read a lot of the documentation about thin stuff, and it isn't clear what's happening.
I took a snapshot with
sudo lvcreate -s --name mySnap1 centos/root
Then I copied that snapshot with
sudo lvcreate -s --name mySnap2 centos/mySnap1
When I try to restore mySnap1 it says:
$sudo lvconvert --merge centos/mySnap1
centos/mySnap1 is not a mergeable logical volume
Hi
Aren't you using some quite ancient version of lvm2 ?
You need to use lvm2 which does support thin volume merging
Regards
Zdenek
