Package: initramfs-tools-core
Version: 0.142
Severity: normal
Dear Maintainer,
* What led up to the situation?
Consider having VM with two ~21.5GB disks and doing fresh installation
Debian installer partitioner setup
1) Created partitions as follows
/dev/vda1 500MB EFI
/dev/vda2 21GB LVM
/dev/vdb1 500MB EFI
/dev/vdb2 21GB LVM
2) Setup LVM as follows
vg_main as VG consists of /dev/vda2 & /dev/vdb2 PVs (~ 2*20GB)
lv_root ext4 10GB LV in vg_main
lv_swap swap 1GB LV in vg_main
Both LVs are created as linear by the installer
3) Finish Debian installation & reboot
4) Boot new system and convert lv_root linear LV to RAID 1
lvconvert --type raid1 vg_main/lv_root -m 1
5) Reboot the machine to ensure it boots and check lvs status
LV VG Attr LSize Pool Origin Data% Meta% Move
Log Cpy%Sync Convert
lv_root vg_main rwi-aor--- 9.31g
100.00
[lv_root_rimage_0] vg_main iwi-aor--- 9.31g
[lv_root_rimage_1] vg_main iwi-aor--- 9.31g
[lv_root_rmeta_0] vg_main ewi-aor--- 4.00m
[lv_root_rmeta_1] vg_main ewi-aor--- 4.00m
lv_swap vg_main -wi-ao---- 952.00m
6) shutdown the machine, disconnect vdb disk and start it again
7) initrd drops to initramfs shell stating it's unable to find root file system
* What exactly did you do (or not do) that was effective (or
ineffective)?
Created a script /etc/initramfs-tools/scripts/local-top/startlvm with the
following content
#!/bin/sh
PREREQ=""
prereqs()
{
echo "$PREREQ"
}
case $1 in
prereqs)
prereqs
exit 0
;;
esac
. /scripts/functions
# Begin real processing below this line
lvm vgchange -ay --activationmode degraded --sysinit
* What was the outcome of this action?
LVM was able to start root LV even if one PV was missing.
* What outcome did you expect instead?
I would expect this to be handled without a need for a custom script.
