Hi all.

 

Just tried to create a new docker and it says I am out of space which is weird because I currenty have 2 dockers and an 100G image. How do I check how much space I have left?

 

root@localhost:# /usr/bin/docker run -d --name="MediaBrowser" --net="host" -v "/mnt/user/dockerdata/mediabrowser/":"/MBServer/ProgramData-Server":rw -v "/mnt/user/":"/mnt/user":rw -v "/etc/localtime":"/etc/localtime":ro mediabrowser/mbserver
Unable to find image 'mediabrowser/mbserver' locally

The command failed.

At the top of the docker page, look for "Docker Volume Info"

Service Status:

Docker image:
/mnt/cache/docker.img
Docker volume info:

devid    1 size 100.00GiB used 100.00GiB path /dev/loop8

Btrfs v3.14.2

 

 

How the hell have I used 100GB with two dockers?

 

Anyway, how do I increase the size?

97.24GiB

 

Thats how much is used with all dockers removed....

Going to click the scrub button and see if that does anything?

 

Scrub complete, I now have 96GB free. Wtf?

btrfs scrub start /var/lib/docker -B -R -d -r 2>&1

Ok, I gave up.

 

I stopped docker, renamed docker.img to docker.img.old and started again with a new docker. Now running 3 dockers without issue and about 2GB space used.
