Sure, glad too...
I wanted to encrypt my volumes so if a drive failed, I could simply pull the disk and send it in for warranty repair. This is ideal in the event of a mechanical failure of the disk as the data has been stored encrypted...I don't have to worry about anybody at the factory reading it. I also wanted the array to autostart on boot/reboot...
LimeTech gave me the following advice:
This can be accomplished by saving your encryption keyfile somewhere on your USB flash boot device, maybe in 'config' directory. Then edit your 'go' file and put this just before emhttp is started:
ln -s /boot/config/keyfile /root
Edit: be sure and make a backup of your USB flash device: Main/Flash click Flash Backup to download a zip of your USB flash contents. Note that this zip file can be fed into our USB Creator tool if needed to migrate to a new USB flash device.
So, I copied the key file to the area suggested, renamed it to keyfile and editted the go file with WordPad to insert the suggested line.
Once I did that, the array autostarts on reboot!
Not helpful if my hardware gets stolen, but good enough for dealing with disk failure/warranty work.
