GRUB have lvm module. Grub doesn't support LVM RAID1 (it supports only RAID 4/5/6 type IIRC). However, I don't recommend using /boot on LVM at the moment since grub support for LVM is limited and unofficial. There's a plan to add official and more robust support though - there are ongoing discussions between grub and LVM team... -- Peter _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
