To Cameleon: You cold say that of "real" hardware raid too! I *much* prefer mdraid but the fears about fakeraid and "real" hardware raid are overblown. To OP: I created an LVM over RAID setup; one RAID1 array, md0, composed of sda1 and sdb1 and one VG, vgsys, with two LVs, lvboot and lvsys. d-i was unable to install grub. I moved to VT2, chrooted /target/, ran "grub-install /dev/sda", "grub-install /dev/sdb", and "update-grub", exited the chroot and the VT, moved back to VT1, and continued the installation by choosing not to install a bootloader. Looking at "/var/log/installer/syslog", I see that d-i ran "chroot /target grub-install --no-floppy --force /dev/sda" and it resulted in an "fopen failed: No such file or directory" error followed by a "grub-probe: error: cannot find a GRUB drive for /dev/mapper/vgsys-lvboot". I assume that my chrooted "grub-install" succeeded because I bind-mounted "/dev" to "/target/dev" and mounted "/target/dev/shm", "/target/dev/devpts", "/target/proc", and "/target/sys". -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
