Open a new cell in Databricks notebook and write the below command:

%fs mounts
OR
display(dbutils.fs.mounts())

As an output, you will get mountpoint, path, and the encryption type.

For someone looking for scala solution

val mounts = dbutils.fs.ls("/mnt/").filter(_.name.contains("is_mounted_blob"))
println(mounts .size)

If the blob is mounted it will give a non zero size.

Try this:

def sub_unmount(str_path):
    if any(mount.mountPoint == str_path for mount in dbutils.fs.mounts()):
        dbutils.fs.unmount(str_path)

sub_unmount('/mnt/flightdata')

Result:

/mnt/flightdata has been unmounted.

Verify with this:

dbutils.fs.ls("/mnt/")
