I tried too but it slows down disk speed to a crawl when there's disk
activity by an order of magnitude (commands take 3-4 seconds to execute
while without LVM they give sub-second responses.)
Hmm, that's strange. I've never seen this and I use LVM since it first appeared
on Linux. On Laptops, I even encrypt the logical volumes without a significant
speed impact.
It's only there where's disk activity. For example, if I have 4 or more
torrents downloading. When that happens, typing "mc" (to start midnight
commander) needs about 4 seconds. It's almost instant without LVM.
The speed impact on one of my servers (100+ shell users) was dramatic.
10 seconds for a simple "ls /" for example.
