I was thinking about your long term here. Make sure to use LVM to create your underlaying partition. Then you can add disk space in the future without having to reformat everything and can just grow your ext3/ext4 partition instead.
With six drives installed, there is no more space to add more drives in the chassis. But thanks for the hint!
Ok.
Oh, one last thing. Don't forget to use the '-E stride=XX,stripe-width=YY (where XX and YY are replaced with the appropriate values) options creating your filesystem on the RAID. Otherwise your disk drive usage will have 'hot spots' and slower than optimal speed. Do a man mke2fs to understand how to use them correctly.

That sounds familiar. I think I read about that when I created the array, but opted for an automatic setup anyway. I'll check up on that again.
Thanks!

I think 'stripe-width' is sadly no more available... isn't it?

<snip> Ahh, but when you replace some of them with larger drives?

Then I'll consider it. ;-)
