 Posted: Sun Nov 08, 2009 3:01 pm Post subject: Sudden LVM problem in initrd ("not found") [SOLVED |
 |
|
I have been running an lvm2 setup from my initrd for quite a while now. Recently I decided to update the initrd using the script I made to originally create it and voila, the Laptop refused to boot.
The error I#m receiving is plain and simple:
| Code: | | /init: line 21: vgchange: not found |
If I drop to a rescue shell and try to execute vgchange (which is a symlink to the lvm binary, statically compiled of course) I get the same error message "not found". If I try to execute any busybox command or even mdadm/cryptsetup it works just fine. It's just lvm2 that's broken. I'm using the latest version available in portage. (2.02.51-r2).
Here is my init script:
| Code: | #!/bin/sh
#mount pseudo filesystems
mount -t proc proc /proc
mount -t sysfs sysfs /sys
CMDLINE=`cat /proc/cmdline`
#sleep 3
#load keyboard map
loadkmap < /etc/kmap-de
#raid
#mdadm --assemble /dev/md2 /dev/sda2 /dev/sdb2
#dm-crypt
#cryptsetup luksOpen /dev/md2 vault
#lvm
vgchange -ay vertex
#try to resume (uswsusp)
resume
#root filesystem
mount -r /dev/mapper/vertex-root /newroot
#restore sanity
umount /proc
umount /sys
#root switch
exec /bin/busybox switch_root /newroot /sbin/init ${CMDLINE} |
My mkinitrd script:
| Code: | #!/bin/sh
cd /usr/src/initrd
rm -rf image
#create image directory
mkdir -v image
cd image
#create a few directories
mkdir -v bin dev dev/mapper dev/vc etc newroot proc sbin sys
cp -v /bin/busybox /sbin/cryptsetup /sbin/lvm /sbin/mdadm /usr/lib64/suspend/resume bin
#devices
cp -a /dev/console /dev/sda2 /dev/null /dev/urandom /dev/snapshot dev
#cp -a /dev/tty1 /dev/fb0 /dev/dri/card0 dev
cp /etc/suspend.conf etc
#create symlinks
ln -vs busybox bin/cat
ln -vs busybox bin/loadkmap
ln -vs busybox bin/mount
ln -vs busybox bin/sh
ln -vs busybox bin/switch_root
ln -vs busybox bin/umount
ln -vs lvm bin/vgchange
ln -vs ../console dev/vc/0
busybox dumpkmap > etc/kmap-de
cp -v ../init .
echo -n "Generating initrd..."
find . | cpio -o -H newc | gzip -9 > /boot/initramfs.gz |
Does anybody have any idea where this is coming from? Using the same scripts I used to boot just fine on this machine. Thanks for any help.

there's been recent changes to udev, device-mapper and lvm2.
perhaps you need to re-emerge udev, or rebuild your initrd image with the latest lvm2 binarys? |

Ok, I found the problem. I must have missed this post-upgrade lvm2 message:
| Code: | * Warning, we no longer overwrite /sbin/lvm and /sbin/dmsetup with
* their static versions. If you need the static binaries,
* you must append .static the filename!
[...] |
So basically, previously lvm2 compiled with the "static" useflag would put a static binary at "/sbin/lvm".
Newer versions put a dynamic version at "/sbin/lvm" and the static version at "/sbin/lvm.static".
Slight adaptation of the mkinitrd script to use the ".static" versions instead fixed the problem.
Took me a while to figure out that "small change"... |

Cheers! |

Sorry, didn't check this topic in a while. Here is the adapted mkinitrd script with the changed lines highlighted. Essentially all you need to do is copy the ".static" version of lvm instead:
New mkinitrd:
| Quote: | #!/bin/sh
cd /usr/src/initrd
rm -rf image
#create image directory
mkdir -v image
cd image
#create a few directories
mkdir -v bin dev dev/mapper dev/vc etc newroot proc sbin sys
cp -v /bin/busybox /sbin/cryptsetup /sbin/lvm.static /sbin/mdadm /usr/lib64/suspend/resume bin
#devices
cp -a /dev/console /dev/sda2 /dev/null /dev/urandom /dev/snapshot dev
#cp -a /dev/tty1 /dev/fb0 /dev/dri/card0 dev
cp /etc/suspend.conf etc
#create symlinks
ln -vs busybox bin/cat
ln -vs busybox bin/loadkmap
ln -vs busybox bin/mount
ln -vs busybox bin/sh
ln -vs busybox bin/switch_root
ln -vs busybox bin/umount
ln -vs lvm.static bin/vgchange
ln -vs ../console dev/vc/0
busybox dumpkmap > etc/kmap-de
cp -v ../init .
echo -n "Generating initrd..."
find . | cpio -o -H newc | gzip -9 > /boot/initramfs.gz |
