We have a docker hosted in Ubuntu 4.4.0-93-generic.
When I tried to create a container I got this error:

INTERNAL ERROR: Cannot create temporary directory!

After some research, I found it was due to the disk space (or lack thereof)

I used df to show the disk space. I am not able to understand the below information,

Filesystem                        Size  Used Avail Use% Mounted on     
udev                              504G     0  504G   0% /dev           
tmpfs                             101G   42M  101G   1% /run           
/dev/mapper/dev--ubuntu--vg-root   27G   27G     0 100% /              
tmpfs                             504G  428K  504G   1% /dev/shm

shm                                64M     0   64M   0% /var/lib/docker
none                               27G   27G     0 100% /var/lib/docker
shm                                64M     0   64M   0% /var/lib/docker
tmpfs                             101G     0  101G   0% /run/user/1000  

Could anyone please explain what this is and am I running out of space?

  • Could you copy/paste the output of df instead of taking a screenshot? – SIGSTACKFAULT Oct 19 '17 at 15:11

    Basically var directory is part of your root file system and this is at 100%. Luckily, you are using logical volumes and so you can provision further disks if required and add the space to the volume. – Raman Sailopal Oct 19 '17 at 15:16
  • On second thought, do df -h – SIGSTACKFAULT Oct 19 '17 at 15:20
  • Do you have any link where I could learn more details on this ? – Raajkumar Oct 19 '17 at 15:21
  • Try this, this or this – SIGSTACKFAULT Oct 19 '17 at 15:23

Long story short, this means that your root filesystem is totally full.
