Question

got huge problem, all my inodes seems to be used. I've cleaned all volumes unused Cleaned all container and images with command -> docker prune

but still it seems that it stay full :

Filesystem      Inodes   IUsed  IFree IUse% Mounted on
none           3200000 3198742   1258  100% /
tmpfs           873942      16 873926    1% /dev
tmpfs           873942      13 873929    1% /sys/fs/cgroup
/dev/sda1      3200000 3198742   1258  100% /images
shm             873942       1 873941    1% /dev/shm
tmpfs           873942       1 873941    1% /sys/firmware

The only thing i think can do this, is a build i'm doing on this machine. This build runs a npm install with many files. Can these files stays on server ? is there any chance i have to delete these temporary files ?

Answer 1

Is there any dangling volumes left in the system? If you have dangling volumes, it may fill up your disk space.

List all dangling volumes

docker volume ls -q -f dangling=true

Remove all dangling volumes

docker volume rm `docker volume ls -q -f dangling=true`
