Issues Mounting exFAT Filesystem with Kernel 6.7.2

Recently, I encountered an issue with mounting exFAT filesystems on my Arch Linux running kernel version 6.7.2. Despite having exfatprogs installed, attempts to mount an SD card result in the error: mount: /sd: unknown filesystem type 'exfat'. The modprobe exfat command returns Module exfat not found, suggesting missing kernel support. This problem began after replacing exfat-utils with exfatprogs. Looking for guidance on resolving this and ensuring proper exFAT support in the current kernel setup.

Re: Issues Mounting exFAT Filesystem with Kernel 6.7.2

If `modprobe exfat` fails, check `uname -r` and accordingly if /usr/lib/modules/<kernelversion>/kernel/fs/exfat exists?

You may have booted an old kernel or updated kernel without rebooting (pacman removes modules of the running kernel, unfortunately).

In that case you may be limited to modules that were included in / loaded by your initramfs or otherwise loaded previously.

Re: Issues Mounting exFAT Filesystem with Kernel 6.7.2

When i remove exfat-utils and install exfatprogs i already had a reboot. I have a sd card on /sd, via fstab with exfat-utils it mount well at begin.
If i have exfatprogs don't
after check again it seem line in fstab can not be same for exfat-utils than exfatprogs
exfat-utils fstab line:
#UUID=E5FF-EDD0 /sd exfat default,umask=0002,gid=984 0 0
genfstab -U /sd generated after perform a "sudo mount /dev/mmcblk0p1 /sd    "
UUID=E5FF-EDD0          /sd             exfat           rw,relatime,fmask=0022,dmask=0022,iocharset=utf8,errors=remount-ro      0  #I add sd on / cose genfstab leave / empty for desing.
Ofcourse it not allow my user to write in it...
if i mount with plasma and perform a
genfstab -U /run/media/festuc/festuc                                                                                                                                          ──(ds.,de febr.03)─┘
# /dev/mmcblk0p1 LABEL=festuc
UUID=E5FF-EDD0          /               exfat           rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,iocharset=utf8,errors=remount-ro       0 1
After modify this line on fstab i have alike sistem than with exfat-utils

Ty for your time

Re: Issues Mounting exFAT Filesystem with Kernel 6.7.2

What is the output of:

# modprobe exfat
uname -r
pacman -Q linux
# dmesg

The dmesg output should be from after a failed mount attempt.  Please use code tags.
