[SOLVED] "Failed to mount /home" error

I'm getting a Failed to mount /home error on startup.

The partition /dev/sda3 I'm trying to mount is created using cgdisk and I give it the code 8302 (/home linux partition) (I wonder if it should be 8300 which is normal linux partition)

In my /etc/fstab I put this line:

 UUID=xxx-xxxx-xxxx-xxxx-xxxx /home ext4 default 0 0

On startup I get the error:

[FAILED] Failed to mount /home
See 'systemctl status home.mount' for details.

I do so and I find:

Mounting /home...
mount: /home: wrong fs type, bad option, bad superblock on /dev/sda3, missing codepage or helper programs, or other error.
home.mount: Mount process exited, code=exited, status=32/n/a
home.mount: Failed with result 'exit-code'.
Failed to mount /home.

Re: [SOLVED] "Failed to mount /home" error

Please use code tags instead of bold text, https://bbs.archlinux.org/help.php#bbcode

There's no point in obfuscating the UUID (it's just a random number to prevent collisions and tells nothing about the actual system), so please post the actual line, or rather the entire fstab (order of entries may matter) and the complete output of "lsblk -f"

bad superblock on /dev/sda3

You did create a filesystem on that partition, did you? That's not the same as creating the partition.

Re: [SOLVED] "Failed to mount /home" error

I know the UUID is random, but I'm just making things easier to read and comprehend.

After I created the partition, I formatted it using

mkfs.ext4 /dev/sda3

I will post my fstab & lsblk once I solve the booting problem (I created another post for it).

Thanks so much!

Re: [SOLVED] "Failed to mount /home" error

Have you checked the filesystem integrity?

fsck.ext4 /dev/sda3

# Home partition (elias)
#UUID=80e61b3e-3b7f-468b-83cc-bffb2f427466 /home ext4 default 0 0

The entry is commented-out so it won't be read but /home should still be mounted automatically because of the partition code[1] — so what happens if you try to mount it manually?

# mount /dev/sda3 /home

Might be worth un-commenting the fstab line and changing the partition code to 8300 to stop systemd trying to automount it.

Re: [SOLVED] "Failed to mount /home" error

I commented it out because otherwise it will show the error.

sudo fsck.ext4 /dev/sda3

e2fsck 1.45.5 (07-Jan-2020)
/dev/sda3: clean, 11/54738944 files, 3718169/218940081 blocks

When I did

mount /dev/sda3 /home

I was not able to launch any programs; creating a new folder on desktop produces error (directory not found). All I could do is close visible windows.

I changed the partition code to 0fc63daf-8483-4772-8e79-3d69d8477de4 (8300), but it had no effect..

Re: [SOLVED] "Failed to mount /home" error

Edit:
No, the partition type doesn't really matter at all, but personally I like to set the type for /home to 8302 / 933AC7E1-2EB4-4F13-B844-0E14E2AEF915 for documentation purposes. (also because of https://www.freedesktop.org/wiki/Specif … tionsSpec/)

Edit2: When you mounted it on top of the existing /home dir, it masked everything that was in there, so if the partition doesn't contain a $HOME for your user, you would get the errors you expeirenced like being unable to create icons on the desktop etc.

Re: [SOLVED] "Failed to mount /home" error

Does mounting it by hand work?

Yes it works, but then if I close open windows (eg. nautilus), I am not able to launch them again through terminal for example.

From terminal I can navigate to /home and it shows it empty with the correct size.

So I can say yes it works.

Re: [SOLVED] "Failed to mount /home" error

Mount the partition to /mnt and then see what is actually contained in it.

Re: [SOLVED] "Failed to mount /home" error

I can already see that there is a single folder 'lost+found' by running ls

Edit:
So manually it is being mounted correctly. But the automatic mounting through the fstab file is not working..

Actually I already tried using rw,relatime instead of default and it did not work.

I'm using the s now.

Let me restart my computer.
