[solved] lvm error loading libudev

bananagogo · 2012-06-03 10:46:21

Hi,

After updating I can't boot my arch linux because lvm volumes can't be found.
"/sbin/lvm: error while loading shared libraries: libudev.so.0: cannot open shared object file: No such file or directory"

There is only a libudev.so.1 in /usr/lib/

Someone getting the same error message?

Hi,

I have the same error since I update my system yesterday. We probably forgot to run "mkinitcpio -p linux" to rebuild an initramfs after updating udev to systemd.

I found no solution at this time.

Thank you for this hint.
Fixed it booting a live system and chroot into my system.
mkinitcpio -p linux there fixed the problem.

Could you explain to me how that works? I dont get it. Where do I have to run this? How can I mount encrypted device? Do I need to have the same kernel version?

Read the wiki page on chroot...

nickik · 2012-06-14 22:49:10

What I don't understand is this, do I have to make a change to the unencrypted /boot or to something that is encrypted. If it has to do with the encrypted part, how do I mount that. If not do I have to chroot into the boot (that is mounted).

I don't understand even understand what the actual problem is, thus I dont understand what I have to use chroot for.

If you don't understand what the problem is, I can't really help you.

If you are experiencing the same error as the OP, then the fix in this thread may be of assistance to you.

You boot from the Live image, unencrypt your encrypted filesystem(s), mount them, chroot into your b0rked environment and then fix it by rebuilding your intiramfs.

To unencrypt your LUKs container(s), you use:

cryptsetup luksOpen /dev/sdx containername

In any event, this thread is marked a solved. If you encounter issues trying to fix your issue, open a new thread with explicit details about your errors and what you have tried as a fix.

Cheers worked for me as well.

aias · 2012-06-19 21:04:34

worked for me as well. I wrote the process for myself. so I am putting it here in case someone needs help. I can expand on it if necessary.
1. boot into install cd
2. unlock encrypted drive
- modprobe dm-crypt
- modprobe dm-mod
- cryptsetup luksOpen /dev/sdx container
(these can be found on /boot/grub/menu.lst file).
enter password
- will open the /dev/sdx drive
3. if lvm
- vgscan
- get the name of the vg
- vgchange -a y {name of vg}
- lvscan should display all lv on device
4. mount root
- mkdir /mnt/arch
- need to know root fs type
- may need to run fs check before mounting
- mount -t fstype /dev/{lvroot_path} /mnt/arch
5. chroot (from change root wiki)
cd /mnt/arch
mount -t proc proc proc/
mount -t sysfs sys sys/
mount -o bind /dev dev/
if seperate partitions for boot usr var, mount them
eg:
mount /dev/<device-or-partition-name> boot/
if network:
cp -L /etc/resolv.conf etc/resolv.conf
chroot . /bin/bash
6. mkinitcpio -p linux
7. reboot

aias described it correctly. If you only have an Ubuntu 11.10 at hand, you need to apt-get lvm2. otherwise, the vg-tools are not available.

rochus · 2012-07-12 19:09:37

Why is this problem still not fixed? I just updated a very outdated computer (last update sometime october '11) and have the same problem again. even worse this time is that I don't have any live cd at hand and only a very slow internet connection.

The howto of aias is working well up to the point of starting mkinitcpio.
This fails with message:
==> ERROR: unable to locate module directory for kernel '3.0-ARCH'

So the new kernel on the system is 3.4, but live cd is coming along with kernel 3.0.

Any idea to continue?

update:
mkinitcpio -k <kernelversion> -p linux

resolves the problem

<kernelversion> can be found at. /lib/modules

Did you forget to mount your boot partition to the chroot's boot? (i.e. /mnt/arch/boot) I had some problem with mkinitcpio as well but figured that an unmounted boot was the problem.

I've just came across this issue, one simple solution that helped me:

sudo ln -sf /usr/lib/libudev.so.1 /usr/lib/libudev.so.0

Just make symbolic link to the file that is already there.

WorMzy · 2016-09-19 10:28:28

Please don't necrobump old topics, especially just to post awful advice. If /usr/lib/libudev.so.1 was the same as /usr/lib/libudev.so.0, then it wouldn't have a different name. Learn what soname bumps are, and why they happen.

Packages which provide /usr/lib/libudev.so.0 are available on the AUR, use one of those if you need it.

Closing.

Arch Linux
