well, you get the idea.
I'm tempted to try to use "bioctl -c 1 -l /dev/sd0,/dev/sd1 softraid0"
and "bioctl -c 1 -l /dev/sd2,/dev/sd3 softraid0" to recreate the
volumes (just like how I created them the first time around), and
*hope like hell* I can get my shit back, but before I do that, I
wanted to get your advice to ensure that's my best possible move.
Hey, you know, maybe it would be best if I reinstalled my previous
snapshot (Feb7 I think) and use _that_ version of bioctl, no?
I could have sworn the man page for fsck(8) said something about rule #1
being "don't panic", but I couldn't find it in there. Must be somewhere
else. So I didn't panic, watched a bit of TV and thought about it...
If "bioctl -d" destroys my crypto partitions but yet they can be found
upon reboot (with the appropriate bioctl command), wouldn't the same
thing apply if bioctl somehow destroyed my RAID1 volumes?
I went back to the previous snapshot and with very sweaty hands I gave
it a try, and yes, it does work. Rerunning the RAID1 creation commands
happily brought back both volumes. I then brought back my crypto
volumes and voila:

All is well. :) I feel like I just got off a really wild rollercoaster
and want to go back for more abuse. With that said...
I'm going to try that patch again, only this time I'm going to try it
out a little differently (more slowly, ahem) and see what's happening.
I'm filled with self-doubt that *I* did something wrong, somewhere.
Besides, my nerves are shot, so I couldn't sleep now if I tried.
I really want that patch to work, dammit.
