 Posted: Sat Jan 17, 2004 3:01 pm Post subject: vfat support |
 |
|
I'm trying to use a Lexar JumpDrive. I enabled vfat in make menuconfig and recompiled. I edited my fstab file. I created a JumpDrive file in /mnt/ .
When I try to mount, however, I keep getting an error saying that vfat is not supported by the kernel. I checked the .config file, and I have VFAT set there.
Where might my error be?
Thanks.

Unless you're able to provide more exact info (e.g. the exact error messages) I suspect that something still went wrong with the kernel. Maybe you compiled it as a module? You can find out with the following commands | Code: | cd /usr/src/linux
grep -i 'vfat' .config |
If you're using a 2.6 kernel replace the first command with | Code: | | cd /usr/src/linux-beta |

The line that I added in fstab:
| Code: |
/dev/sda1 /mnt/JumpDrive vfat noauto,user,rw,unhide 0 0 |
My various commands to try and get the drive to mount:
| Code: |
mount /dev/sda1 /mnt/JumpDrive /*this was before I changed fstab*/
mount -t vfat /dev/sda1 /mnt/JumpDrive
/*before changing fstab and without drive plugged in*/
mount /mnt/JumpDrive /*after modifying fstab*/
|
And this is the error I got, and still get
| Code: |
mount: fs type vfat not supported by kernel
|
when I did the grep command as suggested above, I received:

| /dev/sda1 ? I forget, but where does that come from again? What kind of drive is it, anyway? I mean, USB or IEEE-1394 or... |

Are you sure that you're running the kernel whose .config you're looking at? Post the output of
| Code: | | cat /proc/filesystems |

cat /proc/filesystems yields the following:
| Code: |
nodev rootfs
nodev bdev
nodev proc
nodev sockfs
nodev futexfs
nodev tmpfs
nodev shm
nodev pipefs
nodev binfmt_misc
ext2
nodev ramfs
iso9660
nodev devfs
nodev nfs
nodev smbfs
nodev supermount
nodev autofs
reiserfs
nodev pcihpfs
|
I only have one kernel on my system (as far as I know), so how could my .config not be the right one?

How did you configure your kernel? This just doesn't make any sense....
What kernel sources are you using (including version)?
Just to be sure:
1. You did use some interface (genkernel --config, make menuconfig, make x/gconfig, make config) to configure the kernel instead of just manually editing the .config file?
2. You then built the kernel, installed it properly (i.e., mounted /boot and copied the bzImage over), and are currently running it after a reboot?
Given that neither msdos nor vfat shows up in your /proc/filesystems, this is definitely not a problem with the USB drive. |

I'm using gentoo sources 2.4.20 r6.
I did this:
| Code: |
# cd /usr/src/linux
# cp .config ~/.config
# make mrproper
# mv ~/.config .config
# make menuconfig
# make dep
# make bzImage
# make modules
# make modules_install
# cp arch/i386/boot/bzImage /boot/kernel-2.4.20-gentoo-r6
# cp System.map /boot/System.map-2.4.20-gentoo-r6
|
I noticed that you mentioned to mount /boot before copying the bzImage over. Is this where I went wrong?

That could very well be. You may want to compare the date&time of the kernel config to the bzImage you're loading in /boot. If you reverse the order or forget to mount, the bzImage will be copied to an "alternative" /boot directory! It happened to me several times too, which is why I decided at some point to remove the "noauto" option from fstab... |
