[SOLVED] Trouble with mounting as non-superuser

I am having trouble configuring my fstab to allow me to manually mount my external hard drive after booting. When I mount as superuser with

 sudo mount -U 6e80b340-52a3-4a52-a7f1-11ac2feabd1a /home/damien/Games 

it works great. But when I use

 sudo mount /home/damien/Games 

or

 mount /home/damien/Games 

, it gives the following error:

 mount: /home/damien/Games: wrong fs type, bad option, bad superblock on /dev/sdc1, missing codepage or helper program, or other error. 

This is my fstab (the last line is the line to do with my external drive). I have also tried setting ext4 to auto to no avail.

Re: [SOLVED] Trouble with mounting as non-superuser

It's set up to automount in your fstab, so you wouldn't need to manually use the mount command.  Just `cd` to it, or use whatever you want in it and it would me mounted by systemd.

The error, however, suggest there is another problem.  Please post the output of `lsblk -f`.

Re: [SOLVED] Trouble with mounting as non-superuser

I thought it would only automount on boot, or did I misunderstand the wiki? Here is my lsblk:

Re: [SOLVED] Trouble with mounting as non-superuser

You set up systemd automount, that will take care of mounting on access, however I do think that a device timeout of 1ms is likely to be very sporty, up that to something reasonable, like 1mins or so. Or if you really want to manually mount, remove all the systemd related flags.

Maybe elaborate on your end goal, why do you explicitly want to mount manually or do you actually want an "on-access" automount?

Re: [SOLVED] Trouble with mounting as non-superuser

It doesn't mount on access though, even after increasing the timeout to 1 min (given that by specifying the UUID as root, it mounts just fine in a split second).

Re: [SOLVED] Trouble with mounting as non-superuser

Well "as root" you are manually specifying the mount device and the mountpoint, so it will ignore your fstab.

Is the (unmounted) Games path owned by your user and not root? What's the output of "mount" when successfully mounting the partition? FWIW if I'm reading man mount correctly, the unhide option is bogus and invalid for ext4

And check your dmesg, invalid mount invocations often leave information there.

Re: [SOLVED] Trouble with mounting as non-superuser

Ah yes, the unhide was not allowed. There was no trace of the mounting failures in dmesg, but they were in journelctl (should have looked there before making this post tbh). It said that unhide was an invalid option there. So I got rid of that option and now it works manually, but it does not auto mount, but that is not really a problem. Thanks for all the help everyone!
