[linux-lvm] LVM2 : performance drop even after deleting the snapshot

Hi Everyone, We are evaluating lvm2 snapshots and doing performance testing on it. This is what we are doing : 1. dump some data to lvm2 volume (using fio) 2. take the snapshot 3. delete the snapshot (no IOs anywhere after creating the snapshot) 4. run the fio on lvm2 volume Here
