Is it posible to recover and inactive lvm snapshot (COW table Full) ?

[likid0]

Hi,

I was using a lvm snapshot as the root disk for a VM(kvm) server, the snapshot got full 100% used,  it is renderd unusable and is deactivated.

The problem is I have some info on the VM that I would like to recover if possible, anyone knows if there is a way to reactivate the lvol?.

[~]$ S lvs | egrep '(controller|LV)' (11-05 12:49)

[~]$ S lvscan | grep -i inacti (11-05 12:50)
