problem with root filesystem

[prafulla chandra vejendla]

Hi all ,
i followed newbie guide and i mounted the root filesystem using the NFS. i
have given read/write access to that folder to all in the exports file .but
i am unable to create single directory in the target .why is it so ?? how to
overcome this problem . i have down loaded the root filesystem from the
following website  http://linux.omap.com/pub/filesystem/rootfsosk.tar.bz2
--prafulla chandra

	There are a few possible causes of this, but the most likely is that
you are mounting the filesystem as read-only; make sure you have `rw' in
the `bootargs' environmental variable in u-boot.  Here is what I set
them to when using NFS:

setenv bootargs console=ttyS0,115200n8 noinitrd ip=on root=/dev/nfs rw
nfsroot=${MY_IP}:${PATH_TO_ROOTFS},nolock
saveenv

	If that is not the problem, check the permissions as they are set on
the host system: it is possible, however unlikely, that you have them
set up in some strange way (eg -r-xr-xr-x).

Matthew,

I have the your steps. I have set rw in boot args and my bootargs also looks
like yours. And I have checked the access rights in the HOST and it has
fulll access. But still the problem prevails. What could be the reason.

There are a few possible causes of this, but the most likely is that

you are mounting the filesystem as read-only; make sure you have `rw' in

the `bootargs' environmental variable in u-boot. Here is what I set

them to when using NFS:

setenv bootargs console=ttyS0,115200n8 noinitrd ip=on root=/dev/nfs rw

nfsroot=${MY_IP}:${PATH_TO_ROOTFS},nolock

saveenv

If that is not the problem, check the permissions as they are set on

the host system: it is possible, however unlikely, that you have them

set up in some strange way (eg -r-xr-xr-x).

Hi,

What's the exact error code your system gives when you're trying to create
the folder?

Cheers,
