[GTALUG] Luks on Ubuntu 14.04

[Randy Jonasz]

Hey everyone,

I've been trying to resolve an issue unlocking a luks encrypted 
partition on boot using Ubuntu 14.04.  I've set it up to automatically 
unlock after the root partition's password has been entered by adding 
the target entry into /etc/initramfs-tools/conf.d/cryptroot.  I have 6 
drives in this machine and 5 unlock fine.  The 6th errors out with 
unkonwn fs or bad options or password.  I can unlock the partition after 
boot using the derived key from cryptroot.  I've tried to zero out the 
drive and start over but the problem persists.  Can anyone give me any 
pointers on how to solve this?  The drive is used as a cache drive for 
the zfs file system.

Thanks!

Randy
