CentOS Disk space usage (df command) output is empty [message #697]

When I login to the VE I run 'df -h' and the output is empty such as:

Here's an output from a few of my VEs:

VPS 200
Filesystem Size Used Avail Use% Mounted on
simfs 1.0G 314M 711M 31% /

VPS 201
Filesystem Size Used Avail Use% Mounted on

VPS 202
Filesystem Size Used Avail Use% Mounted on

VPS 203
Filesystem Size Used Avail Use% Mounted on
simfs 4.8G 1.4G 3.4G 30% /

That's the 'df -h' command. Notice 201 and 202 don't present anything.

Here's some more output:

[root@vz1 ~]# vzctl exec 200 mount
simfs on / type simfs (rw,noatime)
proc on /proc type proc (rw,nodiratime)
devpts on /dev/pts type devpts (rw)

[root@vz1 ~]# vzctl exec 204 mount
none on /dev/pts type devpts (rw)

Kind of odd. Anyone got any ideas?

Thanks,

Just a guess but try this from inside the VPS:

mount -t proc proc /proc

Also, did you do this:

ln -s /proc/mounts /etc/mtab

Good Luck!

Awesome, thanks Smile

I actually ended up doing this:

vzctl exec 201 "cat /proc/mounts > /etc/mtab"

Then the disk came up in df.

Awesome Smile

You can just link /etc/mtab to /proc/mounts to achieve the same Smile

vzctl enter XXX
rm -f /etc/mtab
ln -s /proc/mounts /etc/mtab

Thanks!

It would be cool if we could find someone to do a FAQ on these types of technical things, maybe a knowledgebase or something Smile
