SOLVED: External USB disk, if absent, makes boot process fail

Hi,

I have an external SATA hard disk attached via usb to my laptop (/dev/sda1) for backup reasons. Upon booting, it is mounted automatically through an /etc/fstab entry.

Yet: when the hard drive is NOT attached to the machine when it boots, it is of course not only not mounted, but the whole boot process fails!

How can the entire process be dependend upon an external device? that's crazy.

What can I do to just have the mount fail if no external drive is attached, so that the boot process can nevertheless finish?

Thanks

gummo

Where does it fail?

Fstab#External_devices

Thanks loqs! that solved the problem!

I added "nofail,x-systemd.device-timeout=1" to the fstab line.

This happens in the series of mounts that are in /etc/fstab. Errors are "Timeout waiting for device dev-disk-by-***" and "Dependency failed for /mnt/". The journal has systemd messages "local-fs.target: Triggering OnFailure= dependencies", and I am dropped to "emergency mode"

thanks
