Can't mount any drive as read-write, external or internal

Otto500206 · November 30, 2023, 8:27am

When I first installed EndeavourOS with KDE, I could mount my drives using Dolphin.

A few days ago, I set up fstab using KDE Partition Manager. Everything looked like it’s fine, until I rebooted. The system weren’t able to, and still not able to, find the drives I added to fstab. It didn’t booted. I fixed it by using nofail, nobootwait I was now able to boot. But…

None of my drives are mounted as read-write, they are always mounted as read-only
External drives can’t be found on boot, internal ones gets mounted(but as I said, read-only).
Also Dolphin can’t mount, gives this error:
An error occurred while accessing '[label name]', the system responded: The requested operation has failed: Error mounting system-managed device /dev/[partition node]: wrong fs type, bad option, bad superblock on /dev/[partition node], missing codepage or helper program, or other error
KDE Partition Manager can mount but only as read-only.

However, all drives works fine in my Windows 10 installation.

Tried to use fixing commands, for example Windows’ ones or fsck.exfat. Gave no errors. Removed them from my fstab, Dolphin still wasn’t able to mount them. I tried to mount them to different folders, it didn’t worked too.

Here’s my fstab:

UUID=E272-B3C7 /boot/efi vfat noatime 0 2
UUID=5b257c34-fd04-42b2-9ce0-dc3b0db8dc71 / btrfs subvol=/@,noatime,compress=zstd 0 0

UUID=0CA6-383E /mnt/externalB exfat nofail,nobootwait 0 0
UUID=5899-CCA7 /mnt/externalgaming exfat nofail,nobootwait 0 0

(I’m using UUIDs because I want to my files on external disks to to mount on same folders, regardless of when I plugged them. But it doesn’t changes anything even if I use partition nodes.)

your missing defaults in your fstab.

Otto500206 · November 30, 2023, 8:45am

That isn’t the full fstab. Posting full fstab isn’t compatible with BBCode. Here’s the full one:

Am I still missing the defaults? If so, how can I add them? Also, should I do them for NTFS partitions too?

Please post terminal output as text for better readability.

Copy, paste, highlight and press Ctrl-E to format.

nofail do not report errors for this device if it does not exist.

you should remove the nofail to see what errors you get when trying to boot.

thefrog · November 30, 2023, 9:43am

post the output just don’t tell us? If we cant see whats going on how do you expect us to help?

Otto500206 · November 30, 2023, 11:50am

I think you should explain what I should do. As you can see, this post is tagged as “Newbie”.

thefrog · November 30, 2023, 11:58am

its this simple what do you not understand about it?

Otto500206 · November 30, 2023, 11:59am

I thought this place was newbie friendly. Not all of our comunnity are newbie friendly then.

thefrog · November 30, 2023, 12:06pm

since you posted a picture i assumed you knew how to get us the information needed.

Step by Step
open the fstab file and copy the entire contents of the file.
navigate to this page and then paste (right mouse click or key combo Ctrl + v)
highlight the newley pasted text and then press Ctrl + E to format the output for easier reading.
navigate back to the fstab file and close it if not already and as soon as someone can get to it they will look at your post and give information based on the errors we can see.

Learned it today. Not many forums have support for something like this.

thefrog · November 30, 2023, 12:19pm

Please see this thread

a quick read here tells you how to post things to the forum.

we also need to see the output of
lsblk -f

thefrog · November 30, 2023, 12:25pm

First off you are putting the external drives under /mnt which is owned by root. so ofcourse you don’t have permission to access those. you need to change /mnt to something like /home/otto/$DEVICE or some other name you entry should look like this

where you have

UUID=5899-CCA7                              /mnt/externalgaming   exfat            nofail,nobootwait                      0 0

this would be better

UUID=5899-CCA7                              /home/otto/externalgaming   exfat            nofail,nobootwait                      0 0

Otto500206 · November 30, 2023, 12:30pm

Did it. It didn’t worked. They are still read-only. The folder I created works fine however.

thefrog · November 30, 2023, 12:39pm

Since I don’t use any Microsoft formats on my drives I’m not sure why its read only unless it has something to do with the nofail automatically making a drive read only again Since I have never used this option I’m not sure if that is what it does or not.

however you still need to add defaults to the options

from man7.org

defaults use default options. The default depends on the kernel and the filesystem. mount(8) does not have any hardcoded set of default options. The kernel default is usually rw, suid, dev, exec, auto, nouser, and async.

Otto500206 · November 30, 2023, 12:58pm

Both NTFS and exfat doesn’t works. And nofail is necceseary for me because if I don’t add that my system becomes unbootable if it doesn’t finds a certain drive.

Did it. Still mounts read-only.

thefrog · November 30, 2023, 1:15pm

Well good luck
