[SOLVED] changing ownership of disk(s)

adr77 · 2024-10-30 13:51:50

So I'm trying to get my 2 additional disks (one is for Windows formatted as NTFS, and the other one is my games drive formatted as exFAT), and the issue is this:

The disks mount and works fine, but I can't write to them without elevated rights.

for more knowledge:

the Windows drive is /dev/sdb3, mounted at "/run/media/andaro/win", and the games drive is /dev/sda1, mounted at "/run/media/andaro/games" with root being an NVMe drive, "/dev/nvme0n1p3".

Thanks for any possible help!

How do you mount them? What is the output of `mount`? What are the permissions on /run/media/andaro/{win,games}/?

adr77 · 2024-10-30 13:57:49

they mount at boot, I modified my fstab using the ArchISO after installing the ntfs-3g driver for the windows partition.

I don't think it is hurting anything, but you might want to clean up that /etc/fstab. Lot's of duplicate records.

adr77 · 2024-10-30 15:14:17

well, I cleaned it, but it still isn't working... looks nicer, though.

seth · 2024-10-30 15:32:18

Neither NTFS nor FAT have proper posix permission support.
You can control the file permissions globally when mounting the devices w/ uid,gid,dmask and fmask
https://man.archlinux.org/man/core/util … ns_for_fat
https://wiki.archlinux.org/title/NTFS-3 … ermissions

loqs · 2024-10-30 15:38:07

UUID=5418CB9A18CB7A0E   /run/media/andaro/win   ntfs            rw,nosuid,nodev,user_id=0,group_id=0,allow_other,blksize=4096   0 1

If you want to use ntfs-3g you need to change the filesystem type to ntfs-3g. I can not find any reference to user_id=0 and group_id in https://man.archlinux.org/man/ntfs-3g.8#OPTIONS.

adr77 · 2024-10-30 15:41:10

I'm not sure what you mean. I've updated the fs to ntfs-3g, will that help me auto-mount it r/w?

seth · 2024-10-30 15:42:48

You esp. need to use the proper mount options.
user_id=0 and group_id=0 is no only trying to re-own the FS to UID0 (the root) but also not valid for ntfs3, https://docs.kernel.org/filesystems/ntf … nt-options nor https://man.archlinux.org/man/core/util … s_for_ntfs (I guess that's still the legacy ntfs module?)

No idea where you got that idea.

Run

mount

to see what options currently actually apply.

It is mounted read write or you would not be able to write to it even as root. By default ownership is assigned to root and the default dmask and fmask prevent write access to none root users. See the second link seth provided in post #7 to adjust the permissions.

ok, so after updating fstab to ntfs-3g, I can now r/w just fine from the Windows root.

now it's just figuring out how to get the games drive to mount r/w at boot. If you all could, try explaining it in simpler means, I've gone through a hard day at work, plus sirens are going off at the moment in another part of my city, and yap-yap.

Basically asking, simplify it, my brain is a tad off right now.

loqs · 2024-10-30 15:57:23

exfat supports uid gid dmask fmask the same as ntfs-3g so you can make the same adjustments to adjust ownership/access permissions.

adr77 · 2024-10-30 15:58:03

lemme try it, brb

update on the situation, it won't boot with any of the ntfs-3g parameters, however, also on ntfs-3g, i have set the UID and GID to my own (andaro:andaro, 1000:1000), so there's that.

applying anything from the ntfs-3g line onto the exfat line causes the system to boot into maintenance mode. at least it boots into something.

basically just moved everything except rw and blksize

loqs · 2024-10-30 16:32:01

Unmount /run/media/andaro/games then try the following which uses uid and gid instead of user_id and group_id and drops allow_other:

# mount -o rw,relatime,fmask=0022,dmask=0022,iocharset=utf8,errors=remount-ro,nosuid,nodev,uid=1000,gid=1000 /dev/disk/by-uuid/EF5E-4AD4 /run/media/andaro/games
