Sorry for this post. There is trouble, but the details are all wrong.
I was upgrading a machine that was differet from the machine I thought
I was upgrading. Given that, it's no surprise that it appeared to be
upgrading ascii instead of beowulf, or that it had problems with gpt
disks -- there are gpt disks.
The real problem is that it seems to be unable to write to several
sectors at the start of device /dev/sdb. I have no idea why, but it
keeps retrying for hours and hours. Currently it's stuck trying to
write to sector 51. This is while doing something to grub in the
course of the upgrade.
Anyone know how I can
stop it from retrying? By now retrying is
useless.
ctrl-c?
Perhaps that disk is defective and I have to replace it.
If you have smartmontools installed, you can check:
smartctl -a /dev/whatever
As for not being able to stash grub onto a gpt disk, that *is* a
problem. Presumably I have to do something to it to make it
possible, and t make it possible to boot from the gpt disk, but I have
no idea what.
Create a partition at least 1MB in size with no filesystem on it.
(unformatted is the last choice in gparted) Give it a flag of bios_grub in
gparted or type ef02 in gdisk. When it comes to grub-install, grub will
know what to do with it.
Some howtos say it must be the first partition. I haven't found that to be
true. I've put it in the middle and at the end. It works.
