Fix will be in next version, but I'm afraid I cannot say when it happens.

Thanks for the fix. Unfortunately I have not had the chance to test it yet, as for now I have removed the mirror to have a bootable system again.

As I don’t know about the release schedule of GRUB, do you know if this fix will normally be included in the next release, and when approximatetly that will be released?

Could you test attached patch (on top of current GIT)?

LVM has support for two mirror types: "raid1" and "mirror". "raid1" is the default type in the newest versions of LVM and "mirror" is called a "legacy type" in the man page.

The raid1 type does not require manually creating a log volume and has some performance advantages that are similar to those of other RAID1 implementations. See <a href="http://wiki.gentoo.org/wiki/LVM#Mirroring_.28RAID1.29">this manual</a> on how to create raid1 mirrored volumes.

GRUB does not seem to recognise raid1 volumes. In GRUB itself, the volumes are simply not displayed using the "ls" command. GRUB will refuse to boot from raid1 volumes. Also grub-install will fail when the root partition is a raid1 volume, reporting "grub-install: info: unknown LVM type raid1" on the way and in the end complaining about not finding the root device.

This means that a system unexpectedly becomes unbootable if a mirror is added to the root partition using lvconvert. (For the record: The problem disappears again after simply removing the mirror.)
