Fwd: grub-install lvm error

[txemi]

I have got a debian sid installation in an lv and I am not able to
make this installation botable again.

I am quite sure that it is possible as I had no problem in making a
fresh install of debian testing in a new lv in same vg and make it
bootable.

I attach grub-install script.

I also append an lvs view:

Cada 2,0s: lvs -a -o +devices

debianrescue is bootable. grub-install works.
raid is not bootable. I tried to recover it in a chroot from other
install (session dump attached in this message).
The only difference is that the raid lv is a mirrored lv, but I
suspect it is not the point.

Thanks,
txemi.
