Help on storage space

could anybody throw some light on this? the system still has 2.6Tb available, a user (unlimited quota) who used only 160 GB was told that he reaching the limit.

Thanks in advance.

Deleted files go to trash for a period of time before actually getting deleted. It’s possible the user has deleted lots of files, but the trash is taking up lots of space. See if this helps.

If you have shell access you can use the command “ncdu” after install ubuntu package “ncdu” (sudo apt-get install ncdu) Wikipedia ncdu

Then change in “ncdu” to the nextcloud data dir and search the biggest dirs.
