The device is mmcblk1, thats the ssd for user. The mmcblk0 is for the system. I had the same Problem and for me it works. The fstab entry is /dev/mmcblk /media/az01-internal-sd ext4 rw 0 0. After the running e2fsck delete the fstab entry and reboot.

Sry, the right entry for fstab is /dev/mmcblk1 /media/az01-internal-sd ext4 rw 0 0

first backup the fstab file :-)
then add that line below to instruct the os to mount it at boot time.
Before you reboot to take this into account, issue a mount -av command, and check the fs is properly mounted (-a mount all entries from fstab). you see a message like "sucessfully mounted" if any error, revert back and let's us know

Yes, only add the line in a new line. Reboot and run e2fsck.

I have this error : root@mpc-key-61:~# e2fsck /dev/mmcblk1
e2fsck 1.45.6 (20-Mar-2020)
ext2fs_open2: Bad magic number in super-block
e2fsck: Superblock invalid, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/mmcblk1

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>

Found a gpt partition table in /dev/mmcblk1

it works thank you all, I added this line to fstab: /dev/mmcblk1p1 /media/az01-internal-sd ext4 rw 0 0 and did an e2fsck on this partition and everything is back to normal!! Great thank you

/etc runs off a fifo. if you edit anything in etc first do this:

umount /etc

otherwise you will contaminate the etc fifo. it is super-imposed from /media/az01-internal somewhere i forget the file path but if you contaminate it you may run into issues with timestamps on links and files being incorrect and it causing the system to be a bit of a jerk when you boot it up.

Once its unmounted then make your edits and reboot the machine and it should update the fifo in /media/az01-internal/whateverthehellitwasagain
