Bugzilla Bug 79579

I'm not able to mount a vfat partition on my amd64. 
I get the error: mount: wrong fs type, bad option, bad superblock on /dev/hdc2,
       or too many mounted file systems
while trying mount -t vfat /dev/hd.. /mnt/..
I created a partition whit Partition Magic, windows, but it doesn't work.
When i try to do mkfs.vfat i get: mkfs.vfat 2.10 (22 Sep 2003)
mkfs.vfat: Attempting to create a too large file system



Reproducible: Always
Steps to Reproduce:
Mount an vfat partition on amd64

Actual Results:  
Still got the same errors

Expected Results:  
Mounting my partition so i can play some song ;)

I tried also other kernels but still it doesn't work.

Googled following tip "-F 32"
mkfs.vfat -F 32 /dev/hdc2

so, it looks like `mount` failed because it hadnt yet been formatted ...

mkfs.vfat documents the fact that it defaults to FAT12/FAT16 and that if you want
FAT32, you must explicitly run with -F 32 ...

I'm not able to mount it, even when i did an mkfs.vfat - F 32.
He's giving me still the same error.

A friend of mine who has also an amd64, has also the same problem.

I really don't know what i could try else...

What't the output ot "fdisk /dev/hdc" ?

Sorry, output of "fdisk -l /dev/hdc" ...

The output is of fdisk -l /dev/hdc is:

/dev/hdc2          204376      238216    17055864    c  W95 FAT32 (LBA).

But i cannot mount is cause i'll get this message then:

mount: wrong fs type, bad option, bad superblock on /dev/hdc2,
      or too many mounted file systems

Thanx for your help by the way :)

Same issue here. I can't mount a USB key that's formatted VFAT.

Do you have 
- vfat in /proc/filesystems ?
- Probably doublicated entries for the /dev/hdc2 in /etc/fstab 
Could you run mount:
strace -o st.log -v -f mount rest_of_ususal_:mount_command_line
and attach st.log

Yes i have vfat in /proc/filesystems

...nodev   hugetlbfs
        msdos
        vfat
        iso9660
nodev   devfs
        ntfs
nodev   mqueue
...

@Roland bar: strace seems not to work, can you explain again please?
Thx

emerge strace
With strace using as a prefix to your "mount" command, you can trace/log all system calls.
-o st.log #Output to st.log (text file)
-v #verbose
-f #follows fok()'s
So if your regular mount command is:
 mount -t vfat /dev/hdc2 /mnt/hdc2
then issue:
 strace -o st.log -v -f  mount -t vfat /dev/hdc2 /mnt/hdc2
then we have in file st.log all system calls and hopeful seeing whats going wrong....

Otherwise:
- What's the complete command line for the mount command?
  (It properly takes some omitted parameters from /etc/fstab)
- Any entries regarding that partition in /etc/fstab?

Otherwise:
- You are sure, that it contains a valid vfat filesystem? 
- Or are we still stuck at the mkfs.vfat -F 32 /dev/hdc2?
- Can you boot from any live-cd or knoppix or from Windows and that system mounts there?

Created an attachment (id=50048) [edit]
Strace log while mounting

So Roland, i uploaded the st.log as attachement. 
I don't understand some of your further questions, but /dev/hdc2 isn't in my fstab. 
The mkfs.vfat -F 32 works fine too me, it gives no errors.

When i do your strace command i still get the same error, but i hope you can get a hint when you read the st.log.

Thanx

Just an idea, http://bugs.gentoo.org/show_bug.cgi?id=76203 
but doubt that this is the problem...

I have reviewed the source code, and when syscall mount() returns EINVAL, it 
makes an ioctl BLKGETSIZE at the device node. If the return value is 0 (as here),
then following code snippet:
             error(_(
                 "       (could this be the IDE device where you in fact use\n"
                 "       ide-scsi so that sr0 or sda or so is needed?)"));
So, probably /dev/sdb2 (something /dev/sd?2) would be the correct device node.

Jason, this could also be the the hint for you usb-device. Here it's also an (pseudo)SCSI device.....

I experienced similar issues on a normal p3 computer (and a usb stick). This is
an older kernel, so it probably is a userland issue.

Guys i tryed really everything (i think) but still i cannot mount the fat
partition. 
Does anyone has booked some progress, or have some other ideas?

Greetz

Have you tried to get a corresponding SCSI devices (Comment #13 )
fdisk -l /dev/sda 
fdisk -l /dev/sdb
fdisk -l /dev/sdc
If this doesn't show up anything, then:
dd if=/dev/hdc2 of=myhdc count=1 
and attach myhdc to this bug-report 

*** Bug 142667 has been marked as a duplicate of this bug. ***

old bug ... you might want to try updating
e2fsprogs/glibc/strace/kernel/util-linux as the strace output looks screwed up:
1923  stat("/sbin/mount.vfat", 0x7fbfffee40) = -1 ENOENT (No such file or
directory)
1923  mount("/dev/hdc2", "/mnt/windows/", "vfat", 0xc0ed0000, 0) = -1 EINVAL
(Invalid argument)
