So it's monday night and i'm at noisebridge.

I would like to take down the drive that is failing and try to copy it 
onto another drive, so unless anyone objects, i will do this.

I know it will fuck up things but i don't see another way, do you?

maybe someone can help put the pieces back together if it doesn't work 
after i'm done with the dd?

I can try and reboot it, but I don't have faith that it will restart.

Unfortunately, I can't tell what mounts sdb backs:

root at minotaur:/etc/lvm# pvdisplay
Bus error

However, it hosts /boot, so... that's a no good:

root at minotaur:/etc/lvm# mount | grep sdb
/dev/sdb1 on /boot type ext2 (rw)



Anyone have some spare SSDs?
