I was going to say, I didn't do a dist-upgrade, I just did regular old
So what I've done in the meantime is I booted off of my 12.04.2
live-usb-stick. I mounted my other zfs pool ("data_pool"), then dd
if=/dev/sdg of=(path on data_pool)/sdg_file.dd.bin bs=4096 . Let that
spool off the entire 64GB from the boot disk verbatim into a file.
Then I mounted root_pool (as /root_pool2), and did a scrub. No errors
found. Since it's mostly empty, took almost a whole two minutes! :D
Reboot, back to grub. The scrub didn't magically changed the behavior, so
I gave your suggestion a try. Unfortunately, no luck:
Any other ideas? (And thanks so far!)
