Ubuntu 18.04 filesystem filling up
by giobaxx from LinuxQuestions.org on (#4VPSH)
Hello guys
I'm facing a strange problems, in an ubuntu 18.04 i have the disk full, and if i run df -h i see that i'm using 100% of the disk, but if i run du -h / --max-length=1 i see that the disk is about 600 GB of 3 TB( there is only the /partition ). I saw the same using the Disk Usage analyzer.
Anyone of you can tell me to understand what is happening?
i have googled it the problem and i try to run thins command
sudo lsof | grep 'deleted'
that are, from what i have understood, deleted files but still present on the disk and from the output of this command we can see a list of file that however i don't know how to delete. These could be the ones causing the problem?
At the end the problems was solved rebooting the Workstation, this has deleted all these "hidden/cached" files that frankly i really didn't know where to look to find them and delete.
i would like to understand what caused this problem....any help is appreciated.
