Steps to configure Linux system with RAID drive

  1. repartition 500GB_max to 300GB+200GB
  2. backup critical files to 200GB
  3. break 1T's 250MB volume out of md0
  4. partition 1TB to 600+400gb
  5. copy md0's data to 1TB
  6. make 1TB external, 500MB_max internal
  7. reinstall OS
  8. repartition md0
  9. copy files back

Comments on RAID

Using RAID 5 is more complex, but when a drive fails (as did the ST31000340AS) under warranty, sending it back has no data security risk.

External

  • Maxtor 200 GB - media
  • Maxtor 500 GB - backups

50 GB free (June 24/2008). est. 100 GB RAID can be cleared up, 200GB moved external.

NCQ performance on Seagage 7200.11 - http://forums.storagereview.net/index.php?showtopic=26006

The problem with the above config is the array is spread across all working drives, so there can't be fast directory to directory copies. Solution is to move to something like this:

500 + 500 raid1 300gb boot + working/media external 1tb 500gb backup + 500gb working/media
