I would like to have a setting, where Ubuntu Server is installed and booting from a flash drive (SanDisk Cruzer Fit 8GB), with two HDDs running in RAID1 and 4 drives running with RAID0. All drives, except for the pen drive should be encrypted and decrypted when booting up the system, thus, unplugging the pen drive would render the whole system useless. There should be a backup of the pen drive somewhere, just in case the pen drive burns down.

All HDDs should run LVM2. All the writing of files should be on the HDD and only on very rare occasions on the flash drive, since it is really slow.

Are there any good tutorials for this kind up setup?

Really no one in this forum has any advices? – UbuntuNewbie Jul 26 '12 at 17:43
You are demanding quick answers, are you not? There are some instructions how to set up encrypted file systems on debian-administration.org. You might want to have a look there. Why RAID 0? You know you will loos all data when one of the disks craches? Why not just use LVM2 without RAID. Then you might be able to save some data when your disks crash. – Anders Jul 27 '12 at 2:20
Oh, I totally forgot that I can have stripped HDDs with LVM2 without having RAID. Yes that sounds reasonable. Sorry for being pushy. – UbuntuNewbie Jul 27 '12 at 6:39
Have you looked up the instructions at debian-administration.org ? No problems... – Anders Jul 28 '12 at 0:46
