I found in storage/blocks a folder with the number fo a Library that does not show up in my list of Libraries under admin panel / Libraries and that is probably exactly the size that is the differene between used disk space and occupied disk space (~290GB).
Can it be considered safe to rename it and to start seafile again?
What could go wrong?
There is also a huge backup file in storage/seafile-bck (150GB). How can I get rid of that file possibly?
As I said: Help is really appreciated.
