I have an Ubuntu server that stopped working this morning. I logged in and found out that it was out of disk space.

Results of lsblk :

ubuntu partitions

Free space left:

free space left

I can see that the root partition is 100% full, and that's why the server stopped working, however I don't understand why my ex-sysadmin made a partition of 111GB when the drive had 223.6GB of total disk space.

What's the best thing I can do now? Is there any way to increase the space of the actual partition in a safe way without causing any damage to the files inside or the file-system?

Or is there any way that I can clone this SSD to a bigger SSD, however if I clone the SSD I think the problem will remain because the partition will have the same size, right?

Results of df -h :

df -h command

Results of vgdisplay :

I can see that there is 111GB free space on the drive. How can I add it to the existing partition?

  • You can clean up disk space or resize a partition. – Pilot6 Feb 01 '23 at 12:24

  • Do you have physical access to this server or is it a VPS? – karel Feb 01 '23 at 13:04
  • Hi. I have physical access and im logged using putty, I tried the commands @steeldriver pointed me but i got the following error: write error failed: no space left on the device. I understand this is happening because the drive is currently at 100%. Can someone point me of how can i delete some files that are not needed? temporary files? packages? don't know.. something like that. i feel i just need to free up a little space to get this resize comand working – j.manel.br Feb 01 '23 at 13:10
  • @karel is there any folder that i can safely delete without compromising the working state of the ubuntuserver? i am still trying to figure it out the ls and cd commands, still searching for the delete command etc. – j.manel.br Feb 01 '23 at 13:29
  • Root drive is running out of disk space. How can I free up space? – karel Feb 01 '23 at 13:31
  • @karel thank you for pointing that out to me. I am running ubuntu server 20.04.2 LTS do you think its safe to run the "sudo apt autoremove" command without risking loosing any valuable data i have on the server? i have mysql running inside the ubuntu server. thank you – j.manel.br Feb 01 '23 at 14:23
  • I run sudo apt autoremove at least once a week without any problems. If you are able to update the software without getting package management error messages it is safe to run sudo apt autoremove otherwise if you are getting package management error messages you should solve them first. – karel Feb 01 '23 at 14:27
  • @karel damn, still no luck. im getting this error after running sudo apt autoremove: "Do you want to continue? [Y/n] y dpkg: unrecoverable fatal error, aborting: unable to fill /var/lib/dpkg/updates/tmp.i with padding: No space left on device you have any other suggestion? – j.manel.br Feb 01 '23 at 14:33
  • That's a bad error message. It means don't run sudo apt autoremove. Instead you should create additional storage space in your root partition first by adding the 111GB free space to it. You can't do this while the root filesystem is in use!!! Instead boot the Ubuntu live USB that you used to install Ubuntu and run the built-in GParted partition editor application from an Ubuntu live session. Here is a link: How to resize partitions?. – karel Feb 01 '23 at 14:45
  • @karel thank you for the tip, do you think its best for me to clone the entire disk first? or the gpart is easy to use and shouldnt be a problem? thank you – j.manel.br Feb 01 '23 at 15:08
  • Cloning a disk with errors on it clones the errors too. All the experts recommend that you should at least backup all of the data that is currently stored on a partition before resizing that partition. – karel Feb 01 '23 at 15:13
