i try to mount a OneDrive Folder to my Linuxserver. However, as i try mout.cifs with XXX beeing the correct values...

root@XXX:~# mount.cifs //onedrive.live.com/about/en-us/signin/ /usr/plex/share -o user='XXX',password='XXX'

...it returns:

mount error: cifs filesystem not supported by the system
mount error(19): No such device

I installed cifs-utils without any errors. (version 2:6.8-1)

My dear friend google lead me to some websites telling me to check some things:

1.

zgrep -i cifs /proc/config.gz

returns nothing.

2.

modprobe cifs

returns:

modprobe: ERROR: ../libkmod/libkmod.c:514 lookup_builtin_file() could not open builtin file '/lib/modules/4.15.0/modules.builtin.bin'
modprobe: FATAL: Module cifs not found in directory /lib/modules/4.15.0

3.

I tried updating packages, reinstalling cifs-utils, upgrading the kernel, rebooting and recompiling the kernel. Nothing worked for me.

4.

uname -r

returns:

4.15.0

5.

lsb_release -a

returns:

6. the samba-service is up and running.

However, the last lines seem a bit strange to me.

So finally, i am left with no idear. I searched the web for hours but the only soloution i could find was recompilling the kernel. Obvoiusly that did not work for me.

I hope someone can help me. If you need more information, please give me the exact command line as i am relatively new to linux.

Thank you in advance!

PS: Please excuse my bad english. Thanks.

--------UPDATE----------

The command

find /lib/modules/ -name cifs.ko

returs a buch of kernal names:

Which one should i choose? And do i use the....

GRUB_DEFAULT='Example GNU/Linux distribution'

...in the file...

/etc/default/grub

to choose what kernal to boot into? Remember, i do have acces to the server only via ssh after the boot process ist sucessfull. I cannot choose a kernal during boot on a screen.

Thank you in advance. Greetings: Smallmountain

You are not running the kernel shipped with ubuntu:

uname -r
returns:

4.15.0

It should have been 4.15.0-45-generic in current ubuntu 18.04.

Run this to find out which installed kernels have the cifs.ko module on your system, and reboot into that kernel: find /lib/modules/ -name cifs.ko.

On my 18.04 system, for example:

root@nsnx:~# uname -r
4.15.0-45-generic
root@nsnx:~# find /lib/modules/ -name cifs.ko
/lib/modules/4.15.0-44-generic/kernel/fs/cifs/cifs.ko
/lib/modules/4.15.0-45-generic/kernel/fs/cifs/cifs.ko

If you do see a cifs.ko module for your custom 4.15.0 kernel, maybe all you need to do is run depmod -a.

  • Thank you very much for your aswer! I updeated the aswer, so i could print the result of the "find /lib/modules/ -name cifs.ko". Feb 4 '19 at 18:30
