Hi Zdenek, I was thinking more about having few LVs, but with different
amount of data/mapping.
For example, is a very fragmented volume (ie: one written randomically)
significantly slower to snapshot than an almost empty volume? I fully
expect some small difference; however, if an empty volume take 0.2s and
a fragmented one 20s, this would surely be significant.
Note that I never had such a slow snapshot, rather, even on aged and big
volumes, it always take <1s. However, other experiences are welcome.
