[linux-lvm] Snapshot code

["Nallammai S" <snallammai novell com>]

Hi,

I am new to lvm2. I am looking at the lvm2 code primarily to understand how snapshots are taken. When I debugged, i found that in addition to the COW LV, a LV named 'snapshot0' is also created. Why is this LV created?

Thanks in advance
