can't switch_root

[Dutta, Kanishka]

Hello All,

I am trying to use switch_root in order to switch the root from one partition to the other where my actual filesystem resides along with other binaries.
I am using the following commands and getting issue:-

When the system boots up, we are trying to
# mkdir newroot
# mount dev/mmcblk0p14 newroot

whole of system partition gets mounted on newroot successfully, after that:-

# switch_root newroot sbin/init
switch_root: failed to mount moving /dev to newroot/dev: Invalid argument
switch_root: forcing unmount of /dev
switch_root: failed to mount moving /proc to newroot/proc: Invalid argument
switch_root: forcing unmount of /proc
switch_root: failed to mount moving /sys to newroot/sys: Invalid argument
switch_root: forcing unmount of /sys
switch_root: failed to mount moving newroot to /: No such file or directory
switch_root: failed. Sorry.

I am getting the above errors. And not able to understand "Invalid argument".

Can you please help me on this, how to use switch_root and change my rootfs to /media/mmcblk0p14/ where my complete filesystem is?

Thanks in advance ..
