RE: [leaf-user] Bering-uClibc-2.4 mount problem

[Eric S. <e.s...@in...>]

Wing,

What you need is add the ext2.o kernel module to the initrd package to moun=
t an ext2 fs. The kernel module can be found in the kernel tarball.
http://leaf.sourceforge.net/doc/guide/buci-downmod.html

Initrd_ide contains all necessary modules to boot from a fat fs, but if you=
 need ext2, ext3, vfat, reiser, ... you have to add the modules. Including =
them all by default will make the initrd very big.

Minix is used for the initrd so that will work out-of-the-box. It's also po=
ssible to mount fat32 fs, but the contents will be truncated to 8.3. You ne=
ed the vfat.o module for full fat32 support.

You can also add the ext2 module to modules.lrp if the fs is not used in th=
e early boot process.

Eric

Eric,

Which kernel module ? I am using initrd_ide.lrp.=20

Does initrd_ide.lrp include all the necessary modules
?

I did a few experiments with it. What I found are:=20

1) mount /dev/hda1 /mnt on an existing/working Linux
(83) partition=20

> Mounting /dev/hda1 on /mnt failed: Invalid argument

2) mount -t ext2 /dev/hda1 /mnt

> Mounting /dev/hda1 on /mnt failed:  No such device

Note that /dev/hda1 is an existing/working Linux ext2
FS.

3. I "lrpkg -i hdsupp" and then did a fsck.ext2 on
/dev/hda1. It worked fine as I expected - implies the
FS on hda1 is an ext2.=20

4. I got a new disk and did a fdisk to create a new
partition. If I label it fat16 and do a mkfs.msdos on
it, I can  "mount /dev/hda1 /mnt or mount -t msdos
/dev/hda1 /mnt" - no problem. It also works fine with
a new vfat or  minix partition too.=20
If I re-label the same partition as Linux partition
i.e. 83 and do  mkfs.ext2, surprisingly I can "mount
/dev/hda1 /mnt" correctly. However, the same trick
works only sometimes. Why ? Note that this is a new
fdisk not the existing Linux partition. =20
=20
I need to mount an existing/working Linux partition.=20

Any hint ?

Thank you for your help.

mount /dev/hda1=20
