Hi,

since an update some weeks ago the lxc-cgroup command isn't working any longer. My current version is pve-manager/5.2-9/4b30e8f9 (running kernel: 4.15.17-3-pve).

This command doesn't output anything:
# lxc-cgroup -n 509 memory.stat

But this command shows the "normal" output: cat /sys/fs/cgroup/memory/lxc/509/memory.stat

All commands were executed as the root user.

Any ideas about this behavior?

I'm unsure when exactly this behavior occurred the first time, but I think when I updated the system on 2018-07-15 the lxc-cgroup command worked as expected and the next time I've updated (on 2018-09-23) the command was "broken". According to the history files in /var/log/apt/.

Please let me know if you need some more information.

Kind regards,
Bernd
 
Just a follow-up:

After updating the Proxmox host to proxmox-ve: 5.3-1 (running kernel: 4.15.18-10-pve) the command
# lxc-cgroup -n 509 memory.stat

works as before, i. e. the output looks good :)

Regards,
Bernd
