Came up clean. Nothing shown for LBA_first_err. But the fact remains that the drive did err out. smartctl -a shows "Elements in grown defect list: 3", so I suppose that it remapped 3 sectors. I can't find anything in the output that tells me how many spare sectors are available for remapping.

If you take a look at:

http://labs.google.com/papers/disk_failures.pdf

you can see that if a drive have had sectors remapped, the likelihood
that the drive will fail within the next 60 days increase with a
factor 14.

Hm? If you have used the GUI to create the RAID partitions during
installation GRUB should be on both drives.

No, I don't believe I used a GUI; I believe this was originally a text install. grub-install takes a parameter, according to its man page. It's not clear, but I think that passing it /dev/sdb will install it to the second drive. But, reading the man page's description of the --root-directory parameter muddled things a bit. Not sure I understand its purpose.


Can't you do a:

grub-install /dev/md0

if md0 is your /boot partition?
