I have a Ubuntu 18.04 droplet running some docker containers. I added a single volume, and after “some amount of time” (as yet unknown) I get “No space left on device” trying to write to it.
if I cd to the mount point and do a ‘touch’ I get the same message. rebooting the droplet makes it work again.
fstab is: /dev/disk/by-id/scsi-0DO_Volume_dockervol2 /mnt/dockervol2 ext4 defaults,nofail,discard 0 0
anyone come across something similar?

Depending on the size of your disk, the command might take a while to complete. You can then go ahead and delete any of the large files that you do not need.
ducommand which estimates the file space usage:
Then we can
cdinto the largest folder and run the command again:
We would need to do that a few more times until we get to the folder that is using those 5GB.
Note: if you have a database service like MySQL, make sure Not to delete any files manually from the MySQL folder. This would cause issues with your database.
If you are unable to clear any disk space I would recommend upgrading your Droplet.
Lastly, I believe in your case it can be due to high inode usage so do not forget to check the
