Sometime ago I used to mount shared folders from my windows computer using the command :

sudo mount.cifs //computer/folder /mnt -o username=user

However now it bugs and yields :

mount error : cifs filesystem not supported by the system mount

error(19): No such device

Any idea on what might have happened in the meanwhile that prevents it from working ?

The package cifs-utils is installed..

zgrep -i cifs /proc/config.gz

Returns :

#CONFIG_CIFS_STATS2 is not set

All yes except for STATS2 and DEBUG basically

  • zgrep -i cifs /proc/config.gz ? (That shall print if CIFS it is compiled as a module) – grochmal Aug 28 '16 at 0:36

    Good, CIFS is compiled as a module. Load the CIFS module with modprobe cifs and you should be able to perform the mount (i'm ~90% confident). – grochmal Aug 28 '16 at 1:58
  • @grochmal it worked again after a reboot, if it happens again i'll do that, thanks – ChiseledAbs Aug 28 '16 at 3:15

CONFIG_CIFS=m means the CIFS functionality is compiled into a kernel module. If the cifs module isn't loaded after a reboot, you can append a line


to the file /etc/modules. The file lists modules which will be loaded automatically at boot time. To check if the module is already loaded type:

lsmod | grep cifs

If you don't see 'cifs' in the output, it isn't loaded. To load it manually without a reboot:

modprobe cifs

I had a similar problem, the module location was changed because of rolling release arch distribution, so path was different. Reboot
