Hello,

I have problems after I upgraded my LXC Container from Ubuntu 16.04 to Ubuntu 18.04 with do-relase-upgrade:

Failed to attach 321 to compat systemd cgroup /system.slice/nginx.service: No such file or directory

Any idea what I can do now? I have the problems with some service like ssh etc.

Gruß Oliver
 
Could you post the output of:
Code: 
lxc-start -nCTID -lDEBUG -o/dev/stdout

where CTID is the ID of your Container.

Also please the contents of the Container config file under /etc/pve/lxc/CTID.conf
 
Hi,

Thanks for the fast reply:

here is the output

Also the lxc.conf file for this container:

memory: 2048
net0: name=eth0,bridge=vmbr4,gw=192.168.20.254,hwaddr=0E:0B:8C:B6:A9:6A,ip=192.168.20.101/24,type=veth

On the server I checked the mysql service e.g. and have the following error:

/etc/init.d/mysql status:

Code: 
server01 systemd[356]: Failed to attach 356 to compat systemd cgroup /system.slice/mysql.service: No such file or directory
server01 systemd[457]: Failed to attach 457 to compat systemd cgroup /system.slice/mysql.service: No such file or directory

The same with the Nginx service:

/etc/init.d/nginx status:

Code: 
server01 systemd[1]: nginx.service: Failed to reset devices.list: Operation not permitted
server01 systemd[3058]: Failed to attach 3058 to compat systemd cgroup /system.slice/nginx.service: No such file or directory
 
Are these the only error messages? Is there any actual visible problem with the services?

I've tried to reproduce the issue, and I'm getting similar entries in systemctl, but my services are not affected.

Can you for example post the full output of:
Code: 
systemctl nginx status

or the same from some of the "affected" services? As long as these services are running properly, I don't think you should be worrying about it.

On another note, please do not send private messages to staff members if you are looking for personal support. If you need something like that, I suggest you to buy a support subscription.

Is this a problem?

Shouldn't be a problem, and most likely not an LXC bug.

It probably has to do with systemd on Ubuntu, but I'm not sure.
 
Help for others encountering this -- have the same issue, but the services do NOT start.

needed to turn on nesting feature for the container under options > features.

in the /etc/pve/lxc/###.conf file it is:

features: nesting=1
