"Filesystem ntfs not configured in kernel"

I have a laptop with a 128gb SSD and a 1TB HDD. I have Windows installed on the 128GB drive, and the 1TB HDD is split - half is an additional drive for Windows and the other half is where Arch is installed. Until recently I was able to view the files on the Windows drive and the other half of the 1TB drive in Dolphin in Arch. Today I try it and instead get an error saying "Filesystem ntfs is not configured in kernel". If I install the ntfs-3g package I can see the files on them, but everything I'm seeing says that NTFS should be a part of the kernel by default. If I do "lsmod | grep ntfs", it doesn't return anything. Has there been a change in the latest kernel package?

Re: "Filesystem ntfs not configured in kernel"

I didn't found any ntfs related kernel changes. Do you had /boot partition mounted during update? Post output of commands:

uname -a
pacman -Qs linux
modinfo ntfs3
zgrep -i ntfs /proc/config.gz

Re: "Filesystem ntfs not configured in kernel"

I'm not sure if anything was changed.

However in the kernel, 'ntfs' is an ancient/deprecated read-only implementation of NTFS (not enabled, also not as a module, in Arch kernel), and the "new" kernel NTFS filesystem driver with read-write capability is called 'ntfs3'.

So if you have an /etc/fstab entry that said 'ntfs' as filesystem type. Either change to ntfs3 or ntfs-3g (for ntfs as a FUSE filesystem, which you'd have to install).

----

Edit:

ntfs-3g package provides a mount.ntfs helper. If you prefer ntfs3 instead, you could perhaps create mount.ntfs like this:

#!/bin/sh

exec mount -t ntfs3 "$@"

Otherwise just specify instead of relying on auto for ntfs.

There is a mismatch between the version of the kernel that is running and the linux package which is preventing the kernel from loading modules such as ntfs3.  Was the ESP mounted when the linux package was last updated?

Re: "Filesystem ntfs not configured in kernel"

Or you just updated and didn't reboot yet (pacman removes modules of the currently running kernel, unfortunately).

You either work around it or learn to pacman kernel updates only when you're about to reboot anyway.

Re: "Filesystem ntfs not configured in kernel"

It must have been due to the kernel update as everything is working fine now
