Package: grub-pc Version: 1.99~rc1-13 Severity: important *** Please type your report below this line ***
Hi, upon upgrade on a Wheezy/sid system grup-pc fails to install, postinst script fails to run due to an "unknown file-system" error. The system is left in an unbootable state. Only chroot from another system and then Downgrading to 1.98+20100804-14 solve the problem. Manually running "install-grub" gives error about device not existing and unknown file-system. "grub-mkdevicemap" completes without error. "grub-probe" invariably fails with messages about /dev not being mounted and device not existing, no matter what path is used for the target(s) disk(s). Checks show /dev mounted just fine. System is raid1, /boot on separate raid1 with ext4, rest of the system is luks on raid1. Tried latest two grub-pc and grub-common packages from 1.99 serie (from snapshot.debian.org) and they all failed to install properly, only latest 1.98 works. Thank you for your attention. -- Package-specific info: *********************** BEGIN /proc/mounts /dev/mapper/cryptroot / ext4 rw,relatime,errors=remount ro,barrier=1,data=ordered 0 0 /dev/md4 /boot ext4 rw,relatime,errors=remount ro,barrier=1,data=ordered 0 0 /dev/mapper/_dev_md3 /home ext4 rw,relatime,barrier=1,data=ordered 0 0 *********************** END /proc/mounts *********************** BEGIN /boot/grub/device.map (hd0) /dev/disk/by-id/ata-SAMSUNG_HD502HJ_S20BJ90Z323493 (hd1) /dev/disk/by-id/ata-SAMSUNG_HD502HJ_S20BJ9CZB09883 (hd2) /dev/disk/by-id/ata-SAMSUNG_HD502HJ_S20BJ90Z323486 (hd3) /dev/disk/by-id/ata-SAMSUNG_HD502HJ_S20BJ9CZB09877 (hd4) /dev/disk/by-id/ata-WDC_WD5001AALS-00L3B2_WD-WCASY4118453 *********************** END /boot/grub/device.map *********************** BEGIN /boot/grub/grub.cfg # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ]; then load_env fi set default="0" if [ "${prev_saved_entry}" ]; then set saved_entry="${prev_saved_entry}" save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z "${boot_once}" ]; then saved_entry="${chosen}" save_env saved_entry fi } function load_video { insmod vbe insmod vga insmod video_bochs insmod video_cirrus } insmod raid insmod mdraid insmod part_msdos insmod ext2 set root='(md/126)' search --no-floppy --fs-uuid --set 6e23b1fc-1039-48ed-91aa-be7b50d037fb if loadfont /grub/unicode.pf2 ; then set gfxmode=1920x1080 1440x900 1280x720 1024x768 640x480 load_video insmod gfxterm fi terminal_output gfxterm insmod raid insmod mdraid insmod part_msdos insmod ext2 set root='(md/126)' search --no-floppy --fs-uuid --set 6e23b1fc-1039-48ed-91aa-be7b50d037fb insmod tga background_image -m stretch /grub/vladstudio_leaf.tga insmod raid insmod mdraid insmod part_msdos insmod ext2 set root='(md/126)' search --no-floppy --fs-uuid --set 6e23b1fc-1039-48ed-91aa-be7b50d037fb set locale_dir=($root)/grub/locale set lang=fr insmod gettext set timeout=5 ### END /etc/grub.d/00_header ### ### BEGIN /etc/grub.d/05_debian_theme ### insmod raid insmod mdraid insmod part_msdos insmod ext2 set root='(md/126)' search --no-floppy --fs-uuid --set 6e23b1fc-1039-48ed-91aa-be7b50d037fb insmod tga if background_image /grub/vladstudio_leaf.tga; then true else set menu_color_normal=cyan/blue set menu_color_highlight=white/blue fi ### END /etc/grub.d/05_debian_theme ### ### BEGIN /etc/grub.d/10_linux ### menuentry 'Debian GNU/Linux, avec Linux 2.6.38.4-deb64' --class debian --class gnu-linux --class gnu --class os { insmod raid insmod mdraid insmod part_msdos insmod ext2 set root='(md/126)' search --no-floppy --fs-uuid --set 6e23b1fc-1039-48ed-91aa-be7b50d037fb echo 'Chargement de Linux 2.6.38.4-deb64 ...' linux /vmlinuz-2.6.38.4-deb64 root=/dev/mapper/cryptroot ro quiet echo 'Chargement du disque mémoire initial ...' initrd /initrd.img-2.6.38.4-deb64 } menuentry 'Debian GNU/Linux, avec Linux 2.6.38-2-amd64' --class debian --class gnu-linux --class gnu --class os { insmod raid insmod mdraid insmod part_msdos insmod ext2 set root='(md/126)' search --no-floppy --fs-uuid --set 6e23b1fc-1039-48ed-91aa-be7b50d037fb echo 'Chargement de Linux 2.6.38-2-amd64 ...' linux /vmlinuz-2.6.38-2-amd64 root=/dev/mapper/cryptroot ro quiet echo 'Chargement du disque mémoire initial ...' initrd /initrd.img-2.6.38-2-amd64 } ### END /etc/grub.d/10_linux ### ### BEGIN /etc/grub.d/20_linux_xen ### ### END /etc/grub.d/20_linux_xen ### ### BEGIN /etc/grub.d/30_os-prober ### ### END /etc/grub.d/30_os-prober ### ### BEGIN /etc/grub.d/40_custom ### ### END /etc/grub.d/40_custom ### ### BEGIN /etc/grub.d/41_custom ### if [ -f $prefix/custom.cfg ]; then source $prefix/custom.cfg; fi ### END /etc/grub.d/41_custom ### *********************** END /boot/grub/grub.cfg -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (990, 'testing'), (500, 'testing-proposed-updates'), (500, 'unstable'), (101, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.38.4-deb64 (SMP w/8 CPU cores) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages grub-pc depends on: ii debconf [debconf-2.0] 1.5.38 Debian configuration management sy ii grub-common 1.98+20100804-14 GRand Unified Bootloader, version ii libc6 2.11.2-11 Embedded GNU C Library: Shared lib ii libdevmapper1.02.1 2:1.02.63-3 The Linux Kernel Device Mapper use ii ucf 3.0025+nmu2 Update Configuration File: preserv grub-pc recommends no packages.
