After i took first snapshot on several volumes, then do "snap list...", some of snapshots have a few GB, some a few KB, MB, and some of them have 0 in size.
Why is that?
based on my understanding, the first snapshot would be all pointers to the original location of data, the size should be very small, or should be about the same on all first snapshots.
Where are these difference sizes coming from?
Can soembody please help me out here?
