How to find available space on mounted block storage volume?

I have a droplet with 30GB hard drive, and 100GB additional block storage volume. That volume is mounted at /mnt/p4-shareddepot, and accessable there for read and write. How do I get the available space on this drive? As below, I run the df command of that location but it still just returns the result for the original 30GB drive. Any way to check this?

┌──[Mon Jan 22 11:50:38 **********@************ : /mnt/p4-shareddepot]
└─> $ df -h /mnt/p4-shareddepot
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1        30G  8.2G   21G  28% /

Thanks
Richard

Run df -h without any other arguments. That should output space usage details for all available filesystems.

/mnt/p4-shareddepot is showing your Droplet’s local storage filesystem because the directory itself is technically part of it, not the block storage volume. Every file or directory that is inside of it, however, is located on the block storage volume. So, if you run df -h /mnt/p4-shareddepot/file, you should see the block storage volume’s space usage.

Hi Kamaln

Unfortunately this has not worked for me, I still can only see the droplet’s filesystem:
