df shows no file systems processed

Posted on October 23rd, 2015

A df -m command on the system shows:

df -m
df: no file systems processed

on Openvz file systems are mounted on the hostnode. In order for openvz to know about the filesystems it reads /etc/mtab (which shows the data from /proc/mounts).

To fix the issue run

cat /proc/mounts > /etc/mtab

    Try to remount root filesystem:
    mount -o remount,rw /dev/sdXY /

    where X is the disk letter and Y the partition number in sdXY
    then cat /proc/mounts > /etc/mtab
