I am building a NAS/fileserver based around the HP Proliant N54L Microserver. It is going to be used as a central repo for all media (movies, serials, music etc), possibly a dedicated torrent seedbox and any other server-y things I can cook up for it to do.
This server has 4 SATA bays, with two extra SATA ports, one for the boot disk (250GB included) and another for eSATA. It has built in hardware RAID0 and 1, AMD Turion 2.5GHz and 2GB RAM. Pretty beefy for something that cost me the equivalent of $160.
With it I bought 2 Seagate 3TB ST3000DM001 disks, and I have another (already full) 2TB external that I would like to move into the server eventually.
My storage requirements are:
- One large volume accessible on the network.
- Maximize storage: Use all/most of the storage available on the disks dedicated for storage. Thus 8TB (3 + 3 + 2) in total.
- Flexible: 4TB disks are going to become cheaper and I would like to add one or more of them in the near future. I would like to swap out smaller disks for larger ones as well.
- Somewhat safe: If one disk fails I would like to be able to still recover the data from the other disks with relative ease.
Am I asking for too much? Can an LVM volume recover from a busted drive somehow? The data that is going to be stored on the server is not so critical, I can get it back and the critical stuff will be backed up anyway. I do not care for the data on the failed drive, just the data that sits on the other (working) drives.
Many thanks in advance!
