After I use
bdemount to decrypt a Bitlocker encrypted volume on my Linux system, how do I close the volume?
First I decrypt the volume like this
sudo bdemount -p MYPASSWORD /dev/sda1 /mnt/bdem1
This will create a file
/mnt/bdem1/bde1 (930 GB =~ size of disk /dev/sda1).
Then I mount the file like this
sudo mount -t ntfs /mnt/bdem1/bde1 /mnt/sda1_ntfs
I now have the NTFS volume mounted under
/mnt/sda1_ntfs and can access it.
Now for the reverse operation. I can unmount the NTFS volume
sudo unmount /mnt/sda1_ntfs1
But the "decrypted" volume under
/mnt/bdem1/bde1 still exists. How do I "close" this one without damaging anything? To my surprise the file
/mnt/bdem1/bde1 even persists after I log out and then log in again.
I was expecting something like a
bdeumount command, but there is no such thing and the man pages don't mention this "reverse operation" at all.
My system uses Ubuntu 20.04 with bdemount 20190102.
