[ MOUNT ] Can not mount compact flash drive hda (ext3) with 2.6.16

[ MOUNT ] Can not mount compact flash drive hda (ext3) with 2.6.16

[Mario Ohnewald]

Hello List,

i am booting a linux box via NFS. 
When it boot it with a 2.4.32 kernel i CAN mount my compact flash drive
hda.

If i boot a 2.6.16 kernel i CAN NOT.


hdaX is ext3 and ext3 is compiled into the kernel.
Am i missing a kernel option?

More infos:

/dev/hda1 is apparently in use by the system; will not make a filesystem

Attachted is my kernel config of the 2.6.16 kernel.

Do you need more infos?


Thanks, Mario

proc/mounts is the interesting one - the "mount" command
gives you /etc/mtab which may be wrong.

There is a hda, it is a 1GB disk, and it has four partitions.  The
four partitions are correct?

There are other ways hda1 could be busy, such as used for swap
or member of a RAID array.  But I guess this is not the case here?

Well, you could try the -F (force) option and see what happens.
Just make sure "hda1" doesn't somehow refer to another device
in the system.


You may also want to try
cfdisk /dev/hda
and see that the partition layout is the same as with 2.4,
and you might want to check if cat /dev/hda > /dev/null works.
This is all very strange, but more data might get more people interested.
