RE: [microblaze-uclinux] Using NFS with uClinux kernel
Hi,
To use NFS, the following could be a check list you want to
refer to
1) Make sure to config kernel to support
NFS
2) chmod 777 to the dir to be NFS, just in
case
3) export the directory by a line in the file
/etc/exports". The best way is to use "*" for IP, instead of a specific
IP
dir_name
*(rw,no_root_squash,no_all_squash)
4) active NFS. Use "restart" to update the new "exports"
file
/etc/init.d/nfs restart
5) mount NFS
exactly the command you used, in particular
"-o rsize=2048,wsize=2048" as
it won't work without this option
Just to make sure the network is OK by using
"ping"
That's all I use to have successful NFS to run some
application due to read-only filesystem
Good Luck
i hope you can help me, my problem is
next:
i have my uClinux running on my board on a MicroBlaze
processor, and i configured my kernel to support NFS enviroment, where and
application is built on my workstation (lap) and is executed remotely on the
reference board, so when i want to "mount" my "uClinux-dist" directory of
my workstation on the "/mnt" directory of my uClinux (running in the
FPGA board) i execute this command in the uClinux operatin
system:
"mount -t nfs 192.168.1.55:/home/user1/uClinux-cvs/uClinux-dist
/mnt -o rsize=2048,wsize=2048"
the next error message appers:
mount: RPC: Timed out
mount:
nfsmount failed: Bad file dnfs warning: mount version newer than kernel scriptor
NFS: mount program didn't pass remote address!
scriptor
RPC: sendmsg returned error 22
nfs: RPC call returned error 22
nfs_get_root: getattr error = 22
nfs_read_super: get root inode failed
mount: Mounting
192.168.1.55:/home/avnet/uClinux-cvs/uClinux-dist on
/mnt failed : Invalid argument
what is the problem?, what does the message "mount
version newer than kernel scriptor" mean?
thanks
