I created a 2-disk device using a live disk ("mkfs.btrfs -L th -m raid1 -d raid1 /dev/sda1 /dev/sdb1") and Precise was installed on (I chose /dev/sda1 from the d-i partition menu) and was bootable, and sda was mirrored to sdb. I ran bootinfoscript after booting into the install and found that grub was installed in the MBR of sda but not of sdb. I ran "grub-install /dev/sdb", re-ran bootinfoscript, and found that grub2's installed on sdb, but it's "installed in the MBR of /dev/sdb and looks at sector 1 of the same hard drive for core.img. core.img is at this location and uses an embedded config file: ...". (For the record, running "grub-install /dev/sda" installs grub on sda "properly," without embedding.) I rebooted without sda connected and was dropped to an initramfs shell, so "/boot"-on-btrfs isn't yet ready for a multidevice setup; at least not without some extra work like, possibly, installing grub on sdb while booted from a live or rescue disk. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
