nfs issues

[Siim Vahtre]

Hello.

I noticed something similar discussed before but I found no answer..

I downloaded a 700M ISO to a file server and then, as usually, tried
to md5sum it. When I md5summed it where I downloaded it, it was OK.
However, when I did md5sum over NFS, I got _different answers every
time I tried_. Also, I recieved much of these errors on the client
machine during the md5summing period:
"NFS: server cheating in read reply: count 8192 > recvd 1000"
(Server side did not give any errors.)

I have seen this error for many times before but I didn't count it
as anything serious. But when md5sum fails like that, then it means
NFS actually screws the data aswell, right?

The server is 2.4.20
CONFIG_NFS_FS=m
CONFIG_NFS_V3=y
# CONFIG_ROOT_NFS is not set
CONFIG_NFSD=m
CONFIG_NFSD_V3=y
# CONFIG_NFSD_TCP is not set
# CONFIG_NCPFS_NFS_NS is not set

And client is 2.5.66-bk10
CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
# CONFIG_NFS_V4 is not set
CONFIG_NFSD=m
CONFIG_NFSD_V3=y
# CONFIG_NFSD_V4 is not set
# CONFIG_NFSD_TCP is not set

I think that these errors started to come along after I went over to 2.5.

Using 2.4 kernel for client is fine. (tried 2.4.21-pre7 aswell).
But I want to use 2.5 on the client side.. atm it screws the data.

Tough. 2.5.x is a development kernel, and yes, there are still bugs
and issues to be tracked down.
If you need stability use 2.4.x

Nah, I'm fine with 2.5. The benefits are too big to be whiny about
few little bugs ;-)
