History of a Logical Volume named ARCHIVE

This is the history of a storage location named "ARCHIVE" created today. I hope it will stay alive for few years in future.
This ARCHIVE partition is on a 320GB Samsung disk (HD321KJ) which nearly covers the whole disk. Only 1st 2GB is used as SWAP partition just in case a running Linux installation may need or a Live CD may use during boot.
I want to keep all backup on this partition and need to free up the other disks for OS installation which currently hold them.
I intended to give the whole disk for archiving, so a single partition in single PV would have sufficed. But I created 3 partitions of 100GB size and then added them in the volume group (VG). The rationale is if the hard disk started giving problem; such as inode corruption, physical damage, bad bocks, then usually that will affect particular sectors or blocks and not the whole disk. And I can move data of particular physical volume (PV) using "pvmove" to a smaller hard disk (e.g. 120GB) if needed. I hope this granularity will help me in future.
Also, I decided to go for ext4 as it is superior to ext3.
I have done all of the following using openSUSE 11.2 Live CD as it has the latest tools and good support for ext4 (default FS on openSUSE 11.2 is ext4). Though the partitions have been created on the running Debian Lenny installation I had but it does not ext4 partition creation yet. So, the rest is how I have done the things.
