ive been mounting my ntfs filesystem without any trouble for a couple of days until i compiled automounting into the kernal now it says that my kernal doesnt support the ntfs file system and also i couldnt get my automounting to work.


can anyone help me please

Didn't you just forget to compile NTFS support?

sounds like your ntfs support is build as a module(if poss), or the mounting is occuring before the ntfs support is loaded. This would be ok when manually mountuing, but not if you are mounting before the module loads. have a look at the boot squence. You may be able to play around with that.

Build ntfs into the kernel. I have done that in Red hat and automount and it works fine.

[Dolda2000]

Even if it's a module, the kernel should try to auto-load it when a mount is attempted.

[turls]

probably a squence issue where the mounting is being attempted before the module is recognised

check the /proc/filesystem file , the word ntfs has to be written there to let linux support ntfs file system .

[Dolda2000]

From fs/super.c in the kernel source tree:

struct file_system_type *get_fs_type(const char *name)
{
	struct file_system_type *fs;
	
	read_lock(&file_systems_lock);
	fs = *(find_filesystem(name));
	if (fs && !try_inc_mod_count(fs->owner))
		fs = NULL;
	read_unlock(&file_systems_lock);
	if (!fs && (request_module(name) == 0)) {
		read_lock(&file_systems_lock);
		fs = *(find_filesystem(name));
		if (fs && !try_inc_mod_count(fs->owner))
			fs = NULL;
		read_unlock(&file_systems_lock);
	}
	return fs;
}

get_fs_type is called on the filesystem name to use every time you try to mount something.
Notice the "if (!fs && (request_module(name) == 0)) {" line? See? It's not a sequence problem, since the kernel requests the filesystem module if it isn't already present. No offense, I just really wanted to prove my point. Btw., that functionality has been there since at least the 2.2 kernel series, so it's not a version problem.
Smokie: No offense, but isn't it quite obvious that ntfs won't show up in /proc/filesystems when mount explicitly states that the kernel didn't recognize the filesystem type?

bignester: Probably, you just forgot to compile NTFS support. If you are completely certain that you did, double-check to see that the module is installed. Also, check your syslog after the mount attempt to see if it says something useful.
