Not sure where to post this, but I'm still pretty new(b) so here seems appropriate.
I'm looking to repurpose my current windows file server and replace it with a machine runnning Arch. /boot /root & /home will reside on a single drive and then I want something like /data which will be contained on an LVM volume spanning 2 (or 3) drives.
Now:
Having never used LVM before I'm a little wary of the learning curve. How easy is it to setup an LVM system? I've looked at this: http://wiki.archlinux.org/index.php/LVM2#Installation and it seems pretty straightforward but any input would be appreciated. I've setup a couple of Arch systems in the last few months (including the desktop I'm writing this on) so I'm geting reasonably confident about setting up Arch, just the whole partitioning and creating filesystems is comething I've not played around with too much.
Also, if one of the drives in the LVM group dies, is all the data lost or is it possible to recover data from the other drives?

IMHO its pretty easy to set up a LVM system. Its just like partitioning and mounting but with a few extra commands. Keep in mind that you can't do this in the installer, you have to do this beforehand. You can do this before hand using a liveCD so you have a GUI in which you can partition. The lvm creation has to be done via the commandline.
I believe that if one drive dies all the data is lost. If you come by another answer, please let me know:P

so I can't install Arch, get everything else setup and then create my LVM partitions?

Off course you can, I didn't read your post very well, and its not even late yet.
You can just install everything on one drive, and later create /data. Then you don't have to follow that wiki guide. Good luck.

Excellent idea.

Sounds reasonable.

It fairly easy. I followed this Wiki entry which is pretty much step-by-step, copy-and-paste

I want to know this too...

Hard disk failure does not mean that the whole volume is lost. This is a good source of information: Recovering a Lost LVM Volume Disk
With LVM it is possible to attain data redundancy with mirroring. It would then keep two copies of everything (similar to RAID1). You should consider using RAID5 with LVM. Then it would be easy to recover from hard disk failures and resize your partitions.
