Slow boot with NFS, server not responding

Slow boot with NFS, server not responding

I am having trouble booting the kernel with a root file system over NFS.
Once the kernel has mounted the file system, it cycles through this pair of
messages, endlessly:

	nfs: server 192.168.0.39 not responding, still trying
	nfs: server 192.168.0.39 OK

I can't figure out if this is a configuration problem or a hardware problem
with our new board.  Booting in EXTREMELY slow, but manages to make some
progress.  At first, I thought that I had an NFS server configuration or
firewall problem.  But eventually, I discovered that the kernel had some
success mounting the root file system because I started seeing messages from
the init scripts.  Neither the BDI2000 or u-boot had any problem using the
network hardware, so I suspect something must be misconfigured in the
kernel.  While these messages are appearing, I can ping the board without
any dropped packets.

The board is modeled after the Freescale Lite5200 (IceCube), but uses an
MPC5200B processor.  The development environment is ELDK 3.1.1 with the
ELDK's CVS development tree of Linux 2.4.25.

Here is the console log during kernel startup...
I've also attached our kernel .config file.

The "not responding" and "OK" keep repeating at a slow rate,
eventually interspersed with messages from the init process.

Any help would be appreciated.  Thanks.

Re: Slow boot with NFS, server not responding

[Andrei Konovalov]

Hi Edward,

Did you try using ethereal or tcpdump to see what is going on the wire?

I doubt this is your case, but once I've seen a similar behaviour (different
board and CPU!) when an ethernet controller had small Rx FIFO and no DMA, and the
driver was not able to read the first 1.5kB packet of the 4kB NFS read reply
out of the FIFO before the next portion of the same read reply overflows
the FIFO. This led to endless retransmissions etc.
pings are 56-byte + some overhead by default, so they worked OK.

Thanks,
Andrei

We had the same problems on a DBAU1200 board, because that board uses
smc91c111 chip, which has small RX buffers, and a lot of RX overruns
happened.

We solved this by specifying additional kernel command line parameter:
nfsroot=,tcp
which specifies that for the NFS TCP should be used instead of UDP.

I hope this helps.

BR,
Matej

Try connecting to an old half-duplex hub instead of a full-duplex switch to
see if it works. Perhaps the duplex setting is not consistent between the
network driver and PHY.

I have a board with exactly the same symptoms, but I've not yet had the time
to look into this. However using the old hub provided a temporary "fix"...

I ran ethereal on the NFS server and on a PC connected to the same hub as
the target board highlighted the problem.  Many NFS READ REPLY messages from
the server were getting lost on their way to the target board.  The default
timeout was slow (about 1 second) so boot time was grossly extended.  The
packets were getting dropped by a Bay Networks switch.  Bypassing the switch
temporarily solved the problem, but I needed a more robust solution.

I tried that, and the behavior changed only a little bit.  I would still get
the original error messages, but I would also get TCP checksum errors
reported.  I think the problematic switch was being overwhelmed.  I then
looked at other NFS mount arguments, and tried lowering read/write sizes to
fit into a single Ethernet packet.

I tried:
	nfsroot=...,rsize=1024,wsize=1024
and that fixed the problem!

Thanks for the help!
