Out of disk space on /var folder

Hi all

Last year, i have update my NAS (openmediavault) harddrive.

Meanwhile during this month i realize that my /var/ folder are consuming a lot of disk space, and today i run out of disk space.

14G    /var
4.8G    /var/lib
4.2G    /var/folder2ram/var
4.2G    /var/folder2ram
4.1G    /var/tmp/.guestfs-0/appliance.d
4.1G    /var/tmp/.guestfs-0
4.1G    /var/tmp
4.1G    /var/folder2ram/var/tmp/.guestfs-0/appliance.d
4.1G    /var/folder2ram/var/tmp/.guestfs-0
4.1G    /var/folder2ram/var/tmp

So right now my folder is like this.

I don't know what i can eliminate or not, or what is the problem. I have already search this forum but can find anything regarding this.

Right now i have already only 100mb of free space.

Any help will be great. thank you

1. What version of OMV are you using and what are you running it on?
2. What are you using for your boot drive?
3. Anything else you would like to confess before we put the bright lights on you?

Hi, thank you for your reply

Indeed i forgot to mention the specs:

Version is 5.523-1 (Usul)

My boot drive is a nvme with 15GB

I've just 5 HD connected to it beside of the nvme.

Its a simple NAS for file sharig, docker, plex and nothing more.

thank you, but it didnt help, var folder still grows and i dont know what can i do to stop it.

But thank you for your help

Any more ideas?

Post the output of du -shc /var/* your first post doesn't make much sense

Here it goes.

2.4M    /var/backups
98M    /var/cache
4.2G    /var/folder2ram
4.8G    /var/lib
4.0K    /var/local
0    /var/lock
50M    /var/log
4.0K    /var/mail
4.0K    /var/opt
0    /var/run
20K    /var/spool
4.1G    /var/tmp
7.1M    /var/www
14G    total

Thank you

The three folders that stand out are /folder2ram, /lib, and /tmp

Is your boot drive SSD or a USB flash drive?

Is docker deployed in /var/lib?

Yes this is my boot drive an SSD drive

Docker is on a different drive

the var/lib that stand out is because a folder named overlay2 inside docker that i don't have a clue why is there, because i already move docker to another partition.

The 3 folders that you refer are the ones that stands out

Are you sure docker is installed on another drive?

What is the output of

docker info | grep "Docker Root"

Hi

Docker Root Dir: /srv/dev-disk-by-label-Data/docker

Zitat von geaves

Ah! did you do that after you installed docker and some docker containers?

docker info from the cli will output/show where docker is installed

The folder2ram is the flash memory plugin, did you set the #optional settings? that the plugin 'suggests'

My docker root directory is in a different disk

When i first install docker they were by the default locations, only after i ran out of disk space, i move it to another disk.

Docker Root Dir: /srv/dev-disk-by-label-Data/docker

Regarding folder2ram suggestions, i only saw that today. Do i need to go throught that steps?

If you changed it after you installed docker (and presumably had docker containers installed)... the old /var/lib/docker will still be there w/ it's containers. You have to manually delete it from the command line. Unfortunately just changing the path, doesn't move it to the new folder, it simply creates a new docker install at that location.

By the same token, if for some reason you wanted to go back to /var/lib/docker (and you hadn't deleted it).. you could put /var/lib/docker back in the path, restart docker, and all your old containers from before would be there.

Yes you are right, but i remember that i delete all the images, i check the docker file structure and the all the folders on the old path are empty beside that overlay2 that have a considerable amount of files.
