Hello,

We have conferred two LXC containers in a node (Without cluster configured) and Debian 8 as Guest OS.

After reboot, containers are not starting. (In the past the has been rebooted ok).

lxc-start: lxc_start.c: main: 344 The container failed to start.
lxc-start: lxc_start.c: main: 346 To get more details, run the container in foreground mode.
lxc-start: lxc_start.c: main: 348 Additional information can be obtained by setting the --logfile and --logpriority options.​

Trying with extended log, the information is the same:

lxc-start 1451004401.792 ERROR lxc_conf - conf.c:run_buffer:342 - Script exited with status 1
lxc-start 1451004401.792 ERROR lxc_start - start.c:lxc_init:436 - failed to run pre-start hooks for container '201'.
lxc-start 1451004401.792 ERROR lxc_start - start.c:__lxc_start:1170 - failed to initialize the container
lxc-start 1451004406.798 ERROR lxc_start_ui - lxc_start.c:main:344 - The container failed to start.
lxc-start 1451004406.798 ERROR lxc_start_ui - lxc_start.c:main:346 - To get more details, run the container in foreground mode.
lxc-start 1451004406.798 ERROR lxc_start_ui - lxc_start.c:main:348 - Additional information can be obtained by setting the --logfile and --logpriority options.​


We have tried to set, in config of lcx container, the line:

lxc.aa_allow_incomplete = 1​

But not function.

Has anyone had the same problem? Have you been able to solve?
 
Hi,

We try the command. And this is the result:

I do not know what is causing the issue.

can you also post the conf file?
Code: 
cat /etc/pve/lxc/201.conf

with the debug info and .conf file maybe others will be able to help.
 
@vadavo,

Can you try to do a
Code: 
apt-get update
apt-get upgrade

It seems this cgm error is connected to having components of the LXC system in different incompatible versions.

Hello,

This is the result:

Code: 
md5sum /usr/share/lxc/hooks/lxc-pve-prestart-hook
a22dddd26b04bfd260d0aa1afd2ca7e0  /usr/share/lxc/hooks/lxc-pve-prestart-hook

Thanks!
 
I am not sure, but maybe the latest fix for pve-cluster can fix this issue also. Please can you test:

# wget ftp://download1.proxmox.com/debian/dists/jessie/pvetest/binary-amd64/pve-cluster-dbg_4.0-30_amd64.deb
# dpkg -i pve-cluster-dbg_4.0-30_amd64.deb

Does this fix the problem? If not, please can you post the output of 'lxc-start -n 201 -F' again?
 
Hello,

Maybe, it is informative to see the modification time and contents of the file:
/var/lib/lxc/201/config

The error itself seems to imply cgmanager, but could also mean incomplete configuration or binary components. This last explanation has already been ruled out. It would do no harm on the host system to check:
Code: 
cgm listcontrollers
cgm listchildren memory
 
I am getting the same error :-

Tried all the above steps as mentioned, however, nothing resolved the issue.
Anyone has any further resolutions. Please note I am new to proxmox.
