[lxc-users] How to enable df inside a lxc container?

[C. L. Martinez]

Hi all

 Is it possible to display df output inside a lxc container? I have
several CentOS 6.6 based lxc containers, and when I execute df:

[root at lxccos03 elasticsearch]# df -h
df: no file systems processed
[root at lxccos03 elasticsearch]#


But, with a CentOS 7 lxc container, works:


[root at lxccos02 ~]# df -h

What option do I need to enable inside CentOS 6.6 based containers??

Thanks.
