After much searching on Google, a few questions remain open: a. Assuming I can take multiple snapshots of the same volume (I think this was not possible in LVM1), won't it slow down the disks like crazy? If I have a weekly, nightly and a noon snapshots of a volume, I could end up with some write operations becoming a read and four writes per block at the worst case! does that make sense?
b. I see that snapshots can only take up space in the same VG as their original volume, so unless I'm careful with sizes and spans, I'm bound to get the snapshots on the same physical disk as the original LV. Is this a major hit on performance as well, or is it negligable in most cases? c. my snapshots will always be RO, and as such I intend to mark them as read-only LVs, but should I also mount them RO? does it matter?
