Hi,

I guess the reason why matters whatever kind of "pool" file system is
used. For a desktop PC or laptop it's counter-productive to add a new
disk to a pool, if a disk runs out of free space. It's better to add a
disk with more space and copy everything from the old to the new
larger disk. By this approach you know that all the data is on a
particular disk and not randomly spread on a virtual disk build from a
pool of several real disks. For your server farm in the basement you
probably will use FreeBSD and ZFS. In this case, why using Linux at all?

What? You must have been using another LVM then the one Liam and I used
:D.

I don't have any experiences in managing ZFS, since I don't run a
server farm in the basement.

I agree, for almost all usages I would go with something banal as ext4.
