fusermount: fuse device not found, try 'modprobe fuse' first
Hi
I am trying to use ntfs-3g to mount a ntfs harddisk on a fsg3 nas storage device running on 'Linux version 2.6.18' (?).
I have never used Linux and so I am glad, that I got that far.
I installed ntfs-3g on the machine via a package and the later read, that it needs the kernel-module-fuse, so I installed that too.
But still, when I enter
ntfs-3g dev/sdb1 /home/Server

I get this as a reply:
fusermount: fuse device not found, try 'modprobe fuse' first
FUSE mount point creation failed
Unmounting dev/sdb1 (Volume)

What am I missing or doing wrong?
Robert

Re: fusermount: fuse device not found, try 'modprobe fuse' first
Hi,
nas storage device running on 'Linux version 2.6.18' (?).

This is an old kernel on which fuse may be unsafe : see http://www.tuxera.com/community/ntfs-3g-faq/#fuse26
later read, that it needs the kernel-module-fuse, so I installed that too.

Which version of fuse kernel module did you install ? (see above)
I get this as a reply:
Code:
fusermount: fuse device not found, try 'modprobe fuse' first
FUSE mount point creation failed
Unmounting dev/sdb1 (Volume)

What am I missing or doing wrong?

Nothing wrong, but you may have to start fuse after installing. This is done as indicated by typing the command :
modprobe fuse

If this command results in an error, the fuse kernel module was not installed correctly. To check whether it is installed, you may type :
ls -l /lib/modules/`uname -r`/kernel/fs/fuse/fuse.ko

Re: fusermount: fuse device not found, try 'modprobe fuse' first
Hi
I don't know if I can or should change the Linux-Version, because the routerwas build for/with that version. Or is this no problem?
I installed the only available package listed as compatible with the router: kernel-module-fuse_2.6.18-5_armeb.ipk
when I enter modprobe fuse I get an error message and when I enter your code, it answers, that thee is no ../fuse.ko
But when I try to install it again, it states, that the kernel on the nas is up to date and nothing is changed.
What should my next steps be?
Thank you very much so far,
Robert

Re: fusermount: fuse device not found, try 'modprobe fuse' first
sorry, couldn't find the change post button.
I have to correct myself: I used the only version that was tested and deemed stable.

Hi,

You need not change the Linux version, but you should make sure you use a fuse version (I cannot check the fuse version in an ARM module).
I installed the only available package listed as compatible with the router: kernel-module-fuse_2.6.18-5_armeb.ipk
when I enter modprobe fuse I get an error message and when I enter your code, it answers, that thee is no ../fuse.ko

I have checked the contents of kernel-module-fuse_2.6.18-5_armeb.ipk and it contains the file /lib/modules/2.6.18/kernel/fs/fuse/fuse.ko
Check it was installed by issuing :
ls -l /lib/modules/2.6.18/kernel/fs/fuse/fuse.ko

Also check your kernel version by issuing :
uname -r

If the result is not exactly '2.6.18' then this kernel module is not appropriate to your kernel version (post results of both commands).
But when I try to install it again, it states, that the kernel on the nas is up to date and nothing is changed.
What should my next steps be?

You have to make sure the fuse module is installed and started. What is the error when issuing the modprobe command ? You may check the module is started by issuing the command :
lsmod | grep fuse

Re: fusermount: fuse device not found, try 'modprobe fuse' first
Hi
ls -l /lib/modules/2.6.18/kernel/fs/fuse/fuse.ko
returns
-rw-r--r-- 1 root root 46063 Jan 25 2008 /lib/modules/2.6.18/kernel/fs/fuse/fuse.ko

uname -r
returns
2.6.18

modprobe or modprobe fuse returns
-sh: modprobe: not found

lsmod | grep fuse
returns nothing.
BTW: Even if I get everything right at one point, will it ever be possible to mount the ntfs-drive, so that you can use it from windows as a network-drive? (and still be able to plug it directly into your pc if neccessary, regrding the filesystem)?
Thanks so far.
What would be the next thing to try?

Re: fusermount: fuse device not found, try 'modprobe fuse' first
Hi again,
ls -l /lib/modules/2.6.18/kernel/fs/fuse/fuse.ko
returns
-rw-r--r-- 1 root root 46063 Jan 25 2008 /lib/modules/2.6.18/kernel/fs/fuse/fuse.ko
uname -r
returns
2.6.18

So far, so good : the fuse kernel module is installed and matches your kernel.
-sh: modprobe: not found

Well, you have to locate the modprobe command (generally it is in /sbin, but depends on your configuration).You also have to use it as root.
Try
as root :
/sbin/modprobe fuse

lsmod | grep fuse
returns nothing.

No error message such as 'command not found' ? lsmod is generally at the same location as modprobe, so you may also have to enter the full path, such as (you need not be root) :
/sbin/lsmod | grep fuse

BTW: Even if I get everything right at one point, will it ever be possible to mount the ntfs-drive, so that you can use it from windows as a network-drive?

Not sure whether I understand correctly, but if this is on a NAS, the NAS job is to make local drives available as network drives, provided appropriate parameters are entered, and I would expect this to be possible.
(and still be able to plug it directly into your pc if neccessary, regrding the filesystem)?

Yes, however there are significant differences between Linux and Windows, and you may find differences in your file attributes (time stamps, ownership, access rights, etc.).
What would be the next thing to try?

You have to start your fuse module by a modprobe command.

Re: fusermount: fuse device not found, try 'modprobe fuse' first
Hi
sadly I didn't make any progress.
to the modprobe fuse i still get:
/bin/sh: /sbin/modprobe: not found

(I did it as root)
/sbin/lsmod | grep fuse
still returns nothing.
I am sorry, but I have no idea, how I can 'search' for sth. in linux, so i couldn't look eldewhere.
i tried
/sbin/

though and got
/bin/sh: /sbin/: Permission denied

but I don't know if that is relevant. (again as root)
any other ideas/tips?
any kind of filebrowser I could use to look for the fuse files?
thx again
Robert

Re: fusermount: fuse device not found, try 'modprobe fuse' first
Hi,
I have no idea, how I can 'search' for sth. in linux, so i couldn't look eldewhere.

Try the following command as root to locate modprobe (be sure to insert the needed spaces) :
find / -maxdepth 3 -name modprobe

modprobe is a standard Linux command from the package module-init-tools, and if '/sbin/lsmod | grep fuse' does not return an error, lsmod exists in /sbin, and if modprobe is not there, it is nowhere. You may try insmod instead (different syntax) :
# as root :
/sbin/insmod /lib/modules/2.6.18/kernel/fs/fuse/fuse.ko

BTW did you reboot since you installed fuse ? After all it should start automatically.

Re: fusermount: fuse device not found, try 'modprobe fuse' first
Hi jpa,
I am getting the same issues as crashonline
I perform
find / -maxdepth 3 -name modprobe

and it returns
/sbin/modprobe

I perform
/sbin/lsmod | grep fuse or lsmod | grep fuse

and it returns NOTHING lol its driving me crazy.. i have been trying to get this to work for days.. please help!

Which distribution ? which Linux version ? which ntfs-3g version ?

Re: fusermount: fuse device not found, try 'modprobe fuse' first
Hey Jean-Pierre,
Thanks for the reply.
I have been discussing this on another forum aswell.. and from what they have been saying i need to update my kernel version. current specs are below. also i don't require ntfs-3g only sshfs.
Ubuntu 8.10
Kernel version 2.6.18-92.1.22.ex15xen
uname -a

outputs
Linux ServerName 2.6.18-92.1.22.el5xen #1 SMP Tue Dec 16 12:26:32 EST 2008 x86_64 GNU/Linux
So with what i have been told about the kernel version do you know how i can update this to the latest version?
Cheers
Coops

This version is probably not supported any more, so you will have to recompile the fuse kernel module from source, and if you do not know how to do that, you should upgrade the kernel.

Lets get started. The main reason I am writing this when so many articles on this already exist is because many articles do not have all the steps in one place. For example, the article in the FreeBSD Handbook doesn’t have steps for downloading the source using subversion or for making sure you have enough space on the root partition. See this article here: Building and Installing a Custom Kernell

Step 1 – Install FreeBSD as VMWare Guest.

Instructions for installing FreeBSD 9 are found here:

Freebsd Kernel Vs Linux Kernel

Step 2 – Download FreeBSD Source

Instructions for downloading FreeBSD Source can be found here:

Step 3 – Build the GENERIC Kernel

Before you create a custom kernel it is always good to know that the default GENERIC kernel is compiling and working. Also, if you are practiced at this and are certain this will work, feel free to skip this step.

Note: I call it the GENERIC kernel because the GENERIC is the file name of the default kernel configuration.

  1. Go to the /usr/src directory:
  2. As root, run this command:
  3. Wait for the compile to complete

Step 4 – Create a new kernel config

  1. Determine your architecture by running this command:
  2. Look at the last text item in the output string. I have amd64 so that is my architecture: amd64
  3. Change to the directory of the kernel configuration files for your architecture. Remember if you are on a different architecture to replace amd64 in the following command lien with your architecture.
  4. Copy GENERIC to a new file.
  5. Edit KRNL1 with your favorite text editor.
  6. First, change the ident value near the top from GENERIC to KRNL1.
  7. Make any other changes you would like to make.It is hard to know why you are building a custom kernel and hopefully you know what you need in your custom kernel. This is where you modify the kernel to provide what you need.
  8. Save and close your new KRNL1 configuration file.

Step 5 – Build the custom kernel

Film hot shot basketball subtitle indonesia. Now that you have a new configuration file, build a kernel using that configuration file.

  1. Compile the kernel.
  2. Wait for you kernel to build.

Step 6 – Verify you have enough space for the new kernel

  1. Make sure you have enough free space to install your kernel.Note: Your output may be quite different than mine.
  2. If your root partion, /, has a capacity greater than 55%, you probably OK. Otherwise, your backup or kernel installation may fail.

Step 7 – Install the custom kernel

  1. Install the Kernel.
  2. Reboot the system.

Freebsd Kernel Module

You now have a custom kernel installed.
