[ale] Looking for recommendations on LVM + soft Raid on home server

[James Sumners]

Maybe I'm doing it wrong, but I have found having /boot on a non-LVM
partition and everything else managed by LVM to be quite useful. In fact, I
had to resize a root partition on a server I was setting up just today
(well, yesterday at this point) because I forgot to appease the great
Oracle client with way too much swap space (I gave 512MB and it wanted
twice RAM [60GB of swap?! Ridiculous]). It's also handy when you need to
add a new drive into the mix for more free space.

But I'm really just getting used to LVM myself.
