Slack 11.0 - mount -t cifs gives error, not supported by system

sickboylives · 12-11-2006, 07:14 PM

Recently in another thread I was instructed that smbfs is on the way out and that I should use cifs as the filesystem type when mounting a SMB share from Windows.

I issued as root both

Code:

/sbin/mount.cifs //192.168.1.65/D /mnt/verdelet

and

Code:

mount -t cifs //192.168.1.65/D /mnt/verdelet

Both have failed with the following error

Code:

mount error: cifs filesystem not supported by the system
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

My kernel is 2.4.33.3 with no modifications made to it.

What do I need to do to be able to use cifs instead of smbfs?

Have you tried:

Code:

smbmount //<servername-here>/<share-name-here> /path-to-mount-here

From the message I'd say that cifs support wasn't compiled into the kernel, you might have to compile your own or see if it's available as a module. It should be in /lib/modules/*kernelver*/fs/cifs where kernelversion should be the version number of your kernel.
On my system it's compiled as a module in /lib/modules/2.6.17.13/kernel/fs/cifs

A quick way to check if you're using a stock kernel would be to grep the config in boot as well - grep CIFS /boot/config

In my case the config for my current kernel is named config-2.6.17.13 and the above command returns:
CONFIG_CIFS=m
# CONFIG_CIFS_STATS is not set
# CONFIG_CIFS_XATTR is not set
# CONFIG_CIFS_EXPERIMENTAL is not set

Issuing: modprobe cifs - loaded the module right up for me.

P.S. I keep a stock 2.4 kernel installed as well so that I can boot it from lilo
in the event I screw something up too bad to boot, and grepping the config for it returned nothing. You might have to do a compile

Hope this helps a bit.

I am experiencing the same exact problem. It started out with a permissions issue. So I started poking around, and one of the things I did was "unmount" a mount point. After unmounting, I was unable to mount it back with the command below, logged in as root:

Code:

mount -t cifs //servername/share /mnt/net -o username=user,password=password

OR

Note: For the command below I did not specify the type of filesystem because I read somewhere that the system can auto identify the type of filesystem.

Code:

mount //servername/share /mnt/net -o username=user,password=password

For both commands I receive the following error message:

Code:

mount error: cifs filesystem not supported by the system
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

It worked fine & cifs filesystem was supported by the system until I unmounted it. So why can't I mount it back?

Also, I tried the modprobe cifs command and it returned the following:

Code:

[root@10 ~]# modprobe cifs
FATAL: Error inserting cifs (/lib/modules/2.6.18-8.1.6.e15/kernel/fs/cifs/cifs.ko):
Cannot allocate memory

Any help will be most appreciated. Thanks.
