if I run:

$ sudo umount /dev/sdb1 

it works just fine. If the label of the storage devide is red, I'm trying to bypass learning where it's mounted by (script called removedrive):


storage=$(pydf | grep $1 | awk '{ print $1 }')
echo $storage
sudo umount "$storage"


$ removedrive red

Gives me:

umount: /dev/sdb1: no se ha especificado punto de montaje.

I think it's translated as in the title of this question.

So, what I'm doing wrong?


  • What's the system's locale? echo $LANG - wiki.archlinux.org/index.php/locale. – slm Jul 6 '18 at 17:02
  • plz, share fstab and pydf results. – msp9011 Jul 6 '18 at 17:06
  • Is it possible you are trying to umount it more than one time? – Rui F Ribeiro Jul 6 '18 at 17:06
  • You do know you can unmount by mounted path too? For example umount /media/red – roaima Jul 6 '18 at 17:48
  • no, i didn't. that's just great! – kurokirasama Jul 6 '18 at 18:13

You want to unmount by label. Invoke umount directly instead of writing a script:

sudo umount /dev/disk/by-label/$label
