I've got a little embedded box acting as my NAS. It's running Debian (and yes, I know about FreeNAS and openFiler). I've got a pair of 1TB drives doing RAID1. mdadm is fine for me, but others in the household are less... tech savvy. I'd like at least some kind of nice status web interface and ideally enough admin to be able to rebuild a failed drive. Anyone know of anything like that?
You can also check the "palimpsest" tool, more known under the "Disk Utility" name. The tool has GUI (Gnome based) - GUI is very well done, self explaining and simple at the same time + all the functionality is available from GUI (including SMART).
The tool is really well made:
The software is available in all popular linux distributions, like the Ubuntu for instance, usually under the "Disk Utility" name.
