I've been using LVM for quite a while now and prefer it over any existing partitioning method. Especially as this array is for filesharing and I prefer to keep different shares on different partitions and the requirements for sizes are not known at the beginning. Also, the machine this is in uses Xen virtualisation to consolidate different servers on a single machine (power-consumption and most servers only need a lot of resources occasionally) and I already have over 80 LVs just for the virtual machines themselves. (multiple each, as I don't like a single large partition for any machine) As for recovery, I always use "sysrescuecd" (http://www.sysresccd.org) and this has Raid and LVM support in it. (Same with the Gentoo-livecds) -- Joost
