On bootup, error message: Unable to mount..already mounted

Hello - I am in the process of migrating from Linux Mint 18.3 to Manjaro Cinnamon 20.1. I have 3 HDDs in addition to the disk on which Manjaro is installed. Two disks are internal, the third is external connected via usb, labeled “ExternalBackup” with the following line in fstab
LABEL=ExternalBackup /mnt/ExternalBackup auto nosuid,nodev,nofail,x-gvfs-show 0 0

The 2 internal HDDs also each have entries in fstab. I want all 3 to mount on boot.

On first bootup, I get an error message saying “unable to mount ExternalBackup” …already mounted.

It seems its trying to mount the disk twice. Why? And how do I stop it from doing that?

thanks in advance!

Welcome here, @gb13717

To better understand your issue it would be helpful if you would post output of

inxi -Fazy
cat /etc/fstab
sudo parted -l
sudo blkid
sudo efibootmgr -v 

Please, use </> button of the editor to format it.

Even without an fstab entry external discs with formatted partitions could be mounted at boot, that’s true.

Hey thanks you’re right it automatically mounts external discs at boot (unlike my mint system) so all I needed to do was remove the external discs’ entry from fstab

thanks again!
