I'm running archlinux and have an ext3 10Tb internal harddrive that is failing to mount on boot through the fstab entry. If I use mount /dev/sdc1 /media, the mount succeeds however attempting to do a mount -a gives the result

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

I used df -Th to confirm the filesystem and got

 /dev/sdc1      ext3      9.1T  3.8T  4.9T  44% /media

I ran e2fsck to check the disk and got this

sudo e2fsck -f /dev/sdc1
e2fsck 1.45.3 (14-Jul-2019)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/sdc1: 30662/305201152 files (50.0% non-contiguous), 1020563007/2441608704 blocks

Which as far as I understand is all pass.

The fstab entry at the moment is

UUID=239630fb-affe-4810-a3a1-6d7c7958af86   /media      ext3        permissions,defaults    0 0

#/dev/sdc1                  /media      autofs      permissions,defaults    0 0

I've tried ext3, auto, and autofs as the file system for both entries but neither seems to help.

    Add your /etc/fstab to your question. Commented Sep 20, 2019 at 17:10

    Are you sure about the UUID in /etc/fstab? Try changing that line to read /dev/sdc1 /media etx3 permissions,defaults 0 0. Commented Sep 20, 2019 at 17:19
  • ext3, not etx3 - sorry! :( Commented Sep 20, 2019 at 17:34

    I've never come across permissions as a valid option for extN filesystems, and a quick look through the man pages doesn't offer me anything exciting. Are you sure it's valid? Commented Sep 20, 2019 at 17:46
  • Can you mount the filesystem using just mount /media after boot? Commented Sep 20, 2019 at 17:50

The permissions option in your /etc/fstab isn't valid for an ext3 filesystem
