Package: debian-installer Severity: normal Tags: d-i Dear Maintainer,
I created a virtual server with 2 disks of the same size. (Problem wil be the same on a physical server with 2 disks of the same size) I did a minimum installation with : - a partition on the whole disk on each disk of type LVM. (/dev/vda1, /dev/vda2) - a volume group with name rootvg with /dev/vda1 - Everything on lvm, with /dev/rootvg/slashlv mounted on / and /dev/rootvg/swaplv for swap (a minimum partitioned system, I create more logical volume on my servers) - grub on /dev/vda And did a reboot after the installation... I can work on the server without problem... After a successul login under root, I did : - vgextend /dev/rootvg /dev/vdb1 - lvconvert --type raid1 -m 1 /dev/rootvg/slashlv - lvconvert --type raid1 -m 1 /dev/rootvg/swaplv - wait for the raid to be completely rebuilded (I checked with the "lvs" command) I can work on the server without problem... But If I reboot, grub can't regnosize my installation... The message (recopied manually) is : "Booting from Hard Disk... error: disk `lvmid/Gwx3dG-v00h-9hJU-FVuk-Il8Z-bFUK-i6DkfU/KpVdER-OEMM-MWik-vKwM-hWxp-MeJf-LMnsf7' not found. Entering rescue mode... grub rescue>" So I try to reboot with the rescue mode but the CD of debian lack the module "dm-raid" on the kernel part. (Probably on a udeb package but don't know yet exactly which one, so I created this bug report against debian-installer), so I cannot access my disk anymore !!! Imagine you do this on a production server and you did'nt reboot before a long time. For the record, I already filled a bug report for the grub problem on http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=782591 -- System Information: Debian Release: 8.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 3.16.0-4-amd64 (SMP w/1 CPU core) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe".
