I am running a debian-9-torch-xla-v20200208 image on a Google Cloud Platform VM instance and have a 40GB persistent disk attached to it. I am running out of persistent disk space while downloading files using wget.

On running the df -h command, I got the following output which shows that /dev/sda1 is almost full:

Filesystem      Size  Used Avail Use% Mounted on
udev            7.9G     0  7.9G   0% /dev
tmpfs           1.6G   11M  1.6G   1% /run
/dev/sda1        43G   39G  1.8G  96% /
tmpfs           7.9G     0  7.9G   0% /dev/shm
tmpfs           5.3M     0  5.3M   0% /run/lock
tmpfs           7.9G     0  7.9G   0% /sys/fs/cgroup
tmpfs           1.6G     0  1.6G   0% /run/user/1000

I cannot figure out what is filling up disk space on /dev/sda1. Could you please help me solve the issue?

Thanks!

    What did you do to try and find what is filling the device? Use the mount command to find out all the mount points that use sda1 and then use find to list large files. – kaylum Mar 03 '20 at 05:27
  • Used mount|find . -type f -printf "%s\t%p\n" | sort -n | tail -1 and found a zip file that is about 4GB in the home directory. But how does that make up about 39GB at /dev/sda1? – Nizam Mar 03 '20 at 05:39

    You may want to check more than just the largest file. Could be a few large files or many smaller files or mix. – kaylum Mar 03 '20 at 05:41
  • Yes, you are correct @kaylum. Seems there were duplicates in ./.local/share/Trash/files/, which contains binaries that I have been storing in home directory. Any advice on clearing ./.local? I guess unlike ./temp it is not volatile...Thanks again! – Nizam Mar 03 '20 at 05:47
