[BUG] NTFS support missing from 7.0rc3

[Iistros]

Pre-flight checklist

• I have searched existing issues and this is not a duplicate.
• I have read the Contributing Guidelines.
• I have verified the issue is reproducible with the latest available CachyOS kernel.

Upstream / vanilla kernel check

I was unable to test with a vanilla/upstream kernel

Kernel variant

linux-cachyos-rc

System information (cachyos-bugreport.sh)

Kernel 7.0.rc3-1
AMD Ryzen 9800X3D
AMD 7900XT / Mesa 26.0.1
Znver4
SCX_Cosmos

Manual system information (if cachyos-bugreport.sh is unavailable)

Bug description

After updating from 7.0rc2, cachyOS reboots into emergency shell.
Logs shows that it fails to mount NTFS drives due to "filesystem NTFS unknown".

Removing the NTFS drives from fstab allows the system to boot, but the system is unable to mount any NTFS drives in dolphin like it used to do just fine, showing the same "NTFS filesystem unknown".

I tried switching to ntfs3 in fstab but it still can't boot.
NTFS support was fine with 7.0rc2.

Steps to reproduce

1. Update to linux-cachyos-rc 7.0rc3-1
2. If you have any NTFS drives in fstab, it will boot into the emergency shell.
3. If you don't have any NTFS drives in fstab, you can't mount NTFS drives after normal startup.

Expected behavior

System should boot with NTFS drives in fstab, like in 7.0rc2 and every kernel versions before that.

Actual behavior

System can't boot with any NTFS drives in fstab and triggers an emergency shell.

Hello,

we added in 7.0rc3 the new NTFS Driver (rework). This one is not called "ntfs3" its called "ntfs", see:
https://github.com/CachyOS/linux/commits/7.0/ntfs/

If you want to use the progs aditonally please install:
CachyOS/CachyOS-PKGBUILDS@6a5b27a

The ntfs3 driver is incredible broken sadly, so we have some hope backporting "ntfs" will improve the situation.

Hello Peter thanks for your quick answer.
My current fstab is currently working fine since a year with "ntfs", I never used NTFS3.
It seems 7.0rc3 can't load the new driver atm.

Are we supposed to install "ntfsprogs-plus" before updating ? The current configuration will trap any users with NTFS drives in their fstab in an emergency shell if they update without removing the drives from fstab.

This is currently mainly a test for the RC phase testing the new ntfs driver. I think you could try to modprobe "ntfs".

Thanks, "modprobe ntfs" did work while the system was running and I was able to mount NTFS drives in dolphin but the system still can't boot with NTFS drives in fstab even after modprobe.

I'll switch to latest stable kernel while the NTFS driver is currently in the rework.
Thanks!

Maybe yeah. I'm not sure why it doesn't autoload.

I've thought about this, and I think its because the module isn't in the initramfs (because its new). Can you try regenerating the initramfs with ntfs loaded from the 7.0-rc3 kernel? I kept this driver for rc4 but if noone comes back to me with feedback I'll have to drop it in rc5. Thanks.

[Iistros]

I can't get the new NTFS driver running, my system boots correctly on 7.0-rc3 only if ntfs-3g is installed. I soon as I uninstall it, it fails to mount my NTFS volumes and goes into emergency shell at boot.

I didn't have to install ntfs-3g on all previous cachyos kernels, i'll keep it till you guys are working on the new driver.

Send me the command lines I need to run to regenerate the initramfs with the new NTFS kernel driver and i'll test again without ntfs-3g if you want.

Thx for your help

Firstly, you can mark your ntfs drives as nofail so that it won't boot into the emergency shell (or you can also unplug those drives).

Next, boot into the new kernel, modprobe ntfs, mount your ntfs drives (idk if this is needed) then run sudo mkinitcpio -P (or limine-mkinitcpio if ur using limine).

Reboot and check and see if it works correctly.

edit: Make sure you also have backups for the data in the ntfs drive, or it isn't important atleast. I understand if you don't want to go ahead with this in case of data corruption.

Disregard everything I said previously, the module wasn't loading automatically because it was missing https://git.kernel.org/pub/scm/linux/kernel/git/linkinjeon/ntfs.git/commit/?h=ntfs-next&id=040457cfeaea667d6a9d959d04405c94fa9ac7a4

Aha awesome glad you were able to pinpoint the issue, i'll test the next build and report ;)

https://share.cachyos.org/x86_64_v3/kernel/7.0 7.0-rc4-2 should fix this.
