manual mount not mounting usb

lukevin

yes this is a clean install and i disabled usb rom service before beginning this experiment

using the 128gb sandisk drive
i tried to mount /dev/sda1 just now as i was poking around and got this
...
pi@retropie:~ $ sudo mount /dev/sda1
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error

   In some cases useful info is found in syslog - try
   dmesg | tail or so.

@lukevin Sounds like wrong filesystem. Are you sure you entered correct fs and right uuid?

reformating the usb now

sudo mkfs.ext4 /dev/sda1

Sano

Did you try to use PARTUUID=xxxx in fstab (for the sda1 partition), and finding the /dev/sda1 PARTUUID by doing a ls -l /dev/disk/by-partuuid/ ?
Just saying, because existing entries in fstab use PARTUUID...

A mount -v /home/pi/RetroPie after editing fstab could also provide interesting informations.

ok heres what i got

What does the mount -v says ?

Moreover, you have the same partuuid for /boot and your USB, this can't be.
Your boot partition seems to be linked to /dev/sda1

Could you remove the line you added to fstab, issue a tail -f /var/log/messagesin terminal and then plug your usb drive, then copy the result here (the lines appearing after plugging the USB drive) ?

so i took a look at my /boot/cmdline.txt and found that

root=PARTUUID=5728b712-02

i assume it should actually read

root=/dev/mmcblk0p2

i have no idea why that isn't right on a clean img

Sano

No, it's ok. PARTUUID is preferred due to possible device name change with udev.
Your usb drive partition is sda1, but usbmount seems to mount it to /media/usb0.
This should be disabled first if you plan to use fstab, like it's said in the wiki and by @Shadowron .

Edit : my bad, this is usbmount and not usbromservice, but it should be removed if usbromservice is disabled...

so the first thing i did after i made this img and turn on the pi was go to the retropie_setup.sh and disable the usb rom service as per the instructions right?

then i went to find the actual file /etc/usbmount/usbmount.conf
and it was still enabled. fixed that and reran the guide again to no avial

though my uuid changed for sda1 now to

so should my change to fstab be PARTUUID or UUID as per the guide?

lukevin

after saying wrong fs over and over when i would try to mount it suddenly it mounted via a mount command this time. I have no idea why but
how do i add this to fstab and have it mount at boot? i add this to fstab yes?

@lukevin
Ok this seems good now.
It should work by adding the line you mention in /etc/fstab.
The previous UUID you had for sda1 looked like a VFAT UUID (see for example the UUID of /boot).
It may explain why the wrong fs message. After formatting ext4, you got a ext-type UUID and the mount command works.
I don't see another explanation.

@sano

i had to chown my permissions back but this is now solved. windows powershell format and partition to fat32 on my drives originally as the guide was fat32 then changing to ext4 and it seems that when i was doing the new partitioning it just wasn't taking effect for some reason but this is now solved.

thank you sano and shadowron

i've been banging my head on the desk for a week trying to understand linux commands and forcing myself to learn a new OS.
