Hi,
This is the steps that I did.
- the COW data exists on /dev/loop1, including space for the PV header +
metadata
I created a fakevg template file from vgcfgbackup /tmp/fakevg.bkp
( the content of this file I created fake uuid etc... )
I craete a fake uuid for the PV
# pvcreate -ff -u
Hi Mikulas,
Thanks for the replies
I am confused now with the last message?
LVM doesn't support taking existing cow device and attaching it to an
existing volume?
Isn't that what "lvconvert --splitsnapshot" & "lvconvert -s" is ment to
be doing?
lets say that I create the snapshot on a
tions, and restoring the data in seconds using instant recovery
by re-creating or emulating the cow device, and associating all blocks
to an external device?
Regards Tomas

When you create a snapshot of a logical volume.
A new virtual dm- device will be created with the content of the changes
from the origin.
This cow device can than be used to read changed contents etc.
In case of an incident, this cow device can be used to read back the
changed content
