Hello,
after a reboot of Proxmox i am not able to boot a lxc Debian installation anymore.
It is stored in an ZFS-Container. Except from snaphots i did nothing with the storage. ZFS rollback doesn't help.
Where should i look for the cause? Do you think it is Proxmox or something in the container?

thank you in advance!

Thank you for your Answer!

One day later i tried to get you your requestet answer. Out of nothing it works again. I don't get it. I tried two reboots of Proxmox yesterday.
 
Okay, here it is again:

Code:
lxc-start -n 101 -F -lDEBUG -o lxc-101.log
storage does not support content type 'none'
unable to detect OS distribution
lxc-start: conf.c: run_buffer: 405 Script exited with status 2.
lxc-start: start.c: lxc_init: 450 Failed to run lxc.hook.pre-start for container "101".
lxc-start: start.c: __lxc_start: 1321 Failed to initialize container "101".
lxc-start: tools/lxc_start.c: main: 366 The container failed to start.
lxc-start: tools/lxc_start.c: main: 370 Additional information can be obtained by setting the --logfile and --logpriority options.
 
can you post your /etc/pve/storage.cfg ?
 
Hello Dominik,

Code:
ir: local
    disable
    path /var/lib/vz
    shared 0
    content vztmpl,iso
    maxfiles 0

lvmthin: local-lvm
    disable
    vgname pve
    thinpool data
    content none

zfspool: zContainer
    pool naspool/container
    content rootdir
    sparse 0
    mkdir 0

zfspool: zDiskImage
    pool naspool/diskimage
    content images
    sparse 0
    mkdir 0

dir: folderTemplates
    path /naspool/templates
    shared 0
    content vztmpl,iso
    maxfiles 5
    mkdir 0

dir: folderContBackup
    path /naspool/contBackup
    shared 0
    content backup
    maxfiles 5
    mkdir 0

As you see, i use ZFS for the container storage.

thank you in Advance!
Greetings!

according to the config this is a debian container, does the file /etc/debian_version exist?
you can mount the container root system with
Code:
pct mount <CTID>

it will be mounted under
/var/lib/lxc/<CTID>/rootfs

if you can verify that the file exist you can unmount the container with

Code:
pct unmount <CTID>
 
also:

lvmthin: local-lvm
disable
vgname pve
thinpool data
content none

is invalid because the lvmthin storage type does not support a content type "none".
 
Hallo Fabian,
Thank you!
It really was content none

Furthermore it seems that mkdir 0 also generated Problems, but i think that's another problem.
So far it is working again. Thank you a lot!

cat debian_version:
Code:
8.7

p.S. You guys create a great product. Thank you for your work!

Host restart, restore from bck , ... nothing helps

I have no solution after 3 hours. o_O


;)
THE SOLUTION

apt install binutils

[mod edit]: ACTUAL LONG TERM SOLUTION: update to pve-container version 4.3-5

THE SOLUTION

apt install binutils
i also faced the issue on my cluster, but i didnt figure it out untill i saw the post, as i migrated one of the LXC's to a node which apparently had binutils already installed ( even tho i do try to take good care of keeping package-installations all in sync on the nodes).

But as said, this is the solution.

Question remains .. what has changed so this package is now 'required' ?

This also solved my issue. However would appreciate a person with know-how to explain why binutils is the solution.

My problem started following an update of Proxmox to latest version. But why we need binutils is not very clear to me and would appreciate someone in the know to explain why it is needed as it seems unrelated to the problem.

The GNU Binutils are a collection of binary tools. The main ones are:


  • ld - the GNU linker.
  • as - the GNU assembler.
  • gold - a new, faster, ELF only linker.

But they also include:


  • addr2line - Converts addresses into filenames and line numbers.
  • ar - A utility for creating, modifying and extracting from archives.
  • c++filt - Filter to demangle encoded C++ symbols.
  • dlltool - Creates files for building and using DLLs.
  • elfedit - Allows alteration of ELF format files.
  • gprof - Displays profiling information.
  • gprofng - Collects and displays application performance data.
  • nlmconv - Converts object code into an NLM.
  • nm - Lists symbols from object files.
  • objcopy - Copies and translates object files.
  • objdump - Displays information from object files.
  • ranlib - Generates an index to the contents of an archive.
  • readelf - Displays information from any ELF format object file.
  • size - Lists the section sizes of an object or archive file.
  • strings - Lists printable strings from files.
  • strip - Discards symbols.
  • windmc - A Windows compatible message compiler.
  • windres - A compiler for Windows resource files.

Most of these programs use BFD, the Binary File Descriptor library, to do low-level manipulation. Many of them also use the opcodes library to assemble and disassemble machine instructions.


The binutils have been ported to most major Unix variants as well as Wintel systems, and their main reason for existence is to give the GNU system (and GNU/Linux) the facility to compile and link programs.
