[SOLVED] Negative used memory

[ohmer]

Hello,

I installed a ubuntu 16.04 container in a fresly installed Proxmox VE 4.2. When I try to get memory stat inside my container with the "free" command, it reports a negative used memory:

# free
              total        used        free      shared  buff/cache   available
Mem:        2097152      -53128     1998524       66648      151756     1998524
Swap:        524288           0      524288

Found that issue, don't know if this is related: https://github.com/lxc/lxcfs/issues/84

Proxmox does not use LXC 2 (not even beta) yet, so this is most probably the same problem. There is no fix yet, so please be patient.

Hello,

The bug report I linked is against lxcfs pacakge, not lxc. Seem like the current version used by proxmox is 2.0.0.beta1. Is there a way to upgrade to a newer version?

Also, I have this problem only with a ubuntu 16.04 template. The problem doesn't occurs with a ubuntu 12.04 template.

Oh, I did an apt upgrade of my test box and this updated lxcfs to 2.0.2. A reboot later, the issue disappeared.

Yes 2.0.2 is the current version. Always update and reboot before reporting a bug. It is often already fixed in upstream.
