[SOLVED]: Odroid-C4 can not mount external USB drive via fstab on boot?

[rin]

I successfully flashed the "Armbian_24.11.1_Odroidc4_noble_current_6.6.60-kisak.img" on my emmc, and everything boots, runs, and updates fine...

 

 My 2TB USB3.0 seagate HD, /dev/sda, is seen fine in "dmesg", as well as "lsblk" and "blkid", but when I add my UUID, ..., in /etc/fstab it fails to mount at boot.
see below line in /etc/fstab for above /dev/sda1 :
 

UUID=<output-of-bklid-for-sda1>   /media/USB01   ext4   defaults   0   1

To test the above /etc/fstab mount I ran:

sudo findmnt --verify

(which completes successfully)
Also, if I run:

sudo mount -a

(it manually automounts /dev/sda1 -> /media/USB01 successfully).

 

But, whenever i reboot, it does not come up mounted.?

-this is driving me crazy.

Do I also need udisks2 ?, or autofs>, and/or, manually edit udev*?, and/or "systemd-mount" to get this thing to mount on every boot. ?

make the title more clear

Try adding auto to it.

 

UUID=<output-of-bklid-for-sda1>   /media/USB01   ext4   defaults,noatime,auto   0   1

Hi @c0rnelius

Sorry for not being more clear in my Title|Subject, (which I since edited a bit), and thanks for reply, and yes, I tried auto,nofail, ... (in /etc/fstab), and a few other combo's but they didn't work. -It would not consistently mount at boot.  I will post what finally  worked for me in a bit.

exaplanation

[rin]

Automounting, (even permanently on reboot), a portable/external USB-Drive is not as simple as adding a line in /etc/fstab,-like you would do for any internal sata/hdd/ssd/nvme/...
I initially tried installing "autofs" and "udisks2", and fiddling with that and "/etc/fstab", ... and I could get it to automount with the system up, and it would survive the first reboot, but it would NOT mount-at-boot after other consecutive reboots.?!

 

Instead, I ended up re-flashing "Armbian_24.11.1_Odroidc4_noble_current_6.6.60-kisak.img" on my emmc, and followed basically this below guide:
https://unix.stackexchange.com/questions/765721/trying-to-automatically-mount-a-usb-drive-on-debian-bookworm-when-connected
(see "1 Answer" in above link).

-I commented out|removed the "UUID=<output-of-bklid-for-sda1>   /media/USB01 ..." line in my /etc/fstab, since the "systemd-mount" command, triggered by the new udev rule, is now doing the heavy lifting.
The important thing is, I needed my USB-drive to survive reboots and to automount on boot, but before my network comes up, which it now does.

 I'm not exactly sure why this all works, and I still need to fine tune some "systemd-mount" options, ...

 

That said, years ago, on my x86_64-ubuntu-desktop, with "usbmount", lol, I remember simply having to add a line in my /etc/fstab and my USB-drive would automount on boot.

anyway, it appears systemd is everywhere these days, including mounting.

I'll mark this as SOLVED.
