I have two HDDs connected to my Archer C7 V2 running 18.06.01. Each disk has only 1 NTFS partition, mounted on boot by
ntfs-3g /dev/sda1 /HP -o rw,sync ntfs-3g /dev/sdb1 /WD -o rw,sync
One of the disks is used for miniDLNA.
I could unmount the disk that's not used for miniDLNA using
umount. However, or the disk that's used for miniDLNA, I don't seem to be able to unmount it, even after stopping miniDLNA.
root@C7:~# service minidlna stop root@C7:~# root@C7:~# umount /dev/sda1 umount: can't unmount /HP: Resource busy
