I have a Ubuntu 20.04 server running Nextcloud 19. My server got full, so I mounted a 100GB volume. Here is the output of df -h

 $ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            474M     0  474M   0% /dev

/dev/loop4      253M  253M     0 100% /snap/nextcloud/24018
/dev/sda        100G   61M   95G   1% /mnt/volume_nyc1_01
tmpfs            99M     0   99M   0% /run/user/1000

/dev/sda appears to be mounted correctly, but my server doesn't seem to be using it. When I try to update, it reports there is no space left. How can I make the server use the external volume space? What am I doing wrong?

Thanks in advance.

Updates involve storing updating/creating files in many different locations. You (or the system) mounted your external drive on /mnt/volume_nyc1_01 (see here). As a result, you can now store 100GB of files in that folder. This space, however, is not shared among the entire directory structure of your system. For example, you would not be able to put a file in /home/username/Desktop that is 100GB without having space on that drive, even if you do have space in /mnt/volume_nyc1_01. /dev/vda1 is a special file that refers to one of your hard drives (or, more accurately, a partition on one). It is mounted on /, meaning that everything on your system (everything starting with /) that is not in another partition's mount point is on that partition. Since that disk is full, you can no longer store files in places not mounted from another disk (such as /mnt/volume_nyc1_01). Possible ways to utilize this disk space in other places include RAID and mounting a partition in another place, such as /home/username or wherever nextcloud needs it.
