I have been trying to track down a network client/server problem for the last
couple of days and have observed something that does not make sense to me.
HISTORY:
I have a 4/330 server and 1 diskless client and 2 diskfull clients.
The diskless client has been getting NFS server not responding errors
that cause the user GREAT heartburn. Anyway we have been playing with
such things as increasing biod's on client and nfsd's on server,
swapping out the clients motherboard and a list of others that I
won't go into here..
While trying to fix this problem we were running nfsstat .. The
following is how it looked on the SERVER system
Server rpc:
calls badcalls nullrecv badlen xdrcall
2055 0 0 0 0
Server nfs:
calls badcalls
2055 0
null getattr setattr root lookup readlink read
0 0% 395 19% 11 0% 0 0% 297 14% 72 3% 453 22%
wrcache write create remove rename link symlink
0 0% 757 36% 23 1% 7 0% 1 0% 0 0% 0 0%
mkdir rmdir readdir fsstat
0 0% 0 0% 24 1% 15 0%
Client rpc:
calls badcalls retrans badxid timeout wait newcred
1344 0 0 0 0 0 0
Client nfs:
calls badcalls nclget nclsleep
1344 0 1344 0
null getattr setattr root lookup readlink read
0 0% 59 4% 0 0% 0 0% 81 6% 0 0% 129 9%
wrcache write create remove rename link symlink
0 0% 1066 79% 4 0% 0 0% 0 0% 0 0% 0 0%
mkdir rmdir readdir fsstat
0 0% 0 0% 5 0% 0 0%
======> This is the output from the client system ...
Client rpc:
calls badcalls retrans badxid timeout wait newcred
6618 0 150 0 150 0 0
Client nfs:
calls badcalls nclget nclsleep
6618 0 6618 0
null getattr setattr root lookup readlink read
0 0% 1028 15% 24 0% 0 0% 780 11% 199 3% 1906 28%
wrcache write create remove rename link symlink
0 0% 2475 37% 44 0% 19 0% 4 0% 1 0% 0 0%
mkdir rmdir readdir fsstat
0 0% 0 0% 86 1% 52 0%
MY QUESTION:
Shouldn't the number of retrans and timeouts on the client be showing
up on the server...??? Who is lying the CLIENT, the SERVER or my EYES??
Any and all comments are welcome...
Thanks -
Susanne
