How to know if it is safe to remove block storage
I have a block storage volume-nyc1-01 of 1TB attached to the droplet and we would like to remove it.
The volume has not been mounted yet (no entry in
mtab) so I guess I can simply delete it from dashboard.
df -h shows that size of docker volumes are more than 60GB (which is systems SSD).

I would like to know from where these space come from and if its safe to remove the block storage ?
Any help is appreciated.
