[SOLVED] Failed to run lxc.hook.pre-start

Just like andrei-z, I don't understand why the updates broke lxc containers, but installing binutils fixed this issue. If someone here knows why this happened and/or why binutils was the solution, I'd be curious to know.
 
I had the same problem, the solution has (apparently) worked. However, now I can no longer reach my web pages (HTTP ERROR 500) :(
 
Just recording in case anyone else has this happen.

I got the same error in the UI, then I ran this:
Bash:
lxc-start -n 178 -F -lDEBUG -o lxc-178.log
Inspected the log and saw a "disk quota exceeded" message, aka the provisioned disk was full. I expanded the attached root storage and it started right up.
 
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: tools/lxc_start.c: main: 370 Additional information can be obtained by setting the --logfile and --logpriority options.
try to run pct fsck 101 then start the VM machine
the problem is in the storage

okay. it seems like the container is detected as modern (>= 17.10) Ubuntu, which means the network settings you make in PVE will be transferred to the container via systemd-networkd, and that fails.. can you check if the /etc/systemd/network directory exists in the container? (e.g., via "pct mount")?
 
Somehow I've got "disk quota exceeded" on my LXC-100.

I tried the first solution, no effect:
# apt install binutils
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
binutils is already the newest version (2.35.2-2).
0 upgraded, 0 newly installed, 0 to remove and 5 not upgraded.

Next I tried the debug:

had a similar issue- power went out. container wouldnt start

making a backup and restoring it fixed my issue.
 
My problem was disk usage inside container, I had to clean up. In my case I use container id 100, change for your needs:
  • mount container:
    Code:
    pct mount 100
  • inspect and delete files inside container, eg compressed logfiles if not needed any more:
    Code:
    cd /var/lib/lxc/100/rootfs/ && rm var/log/*gz
  • umount container:
    Code:
    pct unmount 100
  • start container:
    Code:
    pct start 100
This solved my issue ...
 
Still happens

A simple container (ID 50013) cannot be started all of a sudden.
Single tiny, disk on zfs pool storage.
This happened suddenly after a while of not using it.

Created another (ID 50014) just like it with "exact" same config and starts.
The 50014 does not start with disk of 50013.


Proxmox itself is on zfs and so are the LXC and VM disks.
Pools report no errors.
Is there any form of way to check virtual disk's health?
... as part of proxmox lifecycle, startup, shudown, etc.

Hi everyone!
I have a similar problem.
Suddenly my LXC no longer wants to start. It ran smoothly for over a year.

Here's the config:
