Diskless nfs problem

[Radek Krejča]

Hello,

I have about 100 diskless freebsd routers and I have problem with huge traffic to nfs server. The mostly traffic is generated by requesting file rights over GETATTR CALL to lib files, eg.

./lib/libc.so.7

Is there any chance to change this behavior? My diskless machines are booted over pxe described at http://www.freebsd.org/doc/handbook/network-diskless.html .

My load of nfs server is (because of this behavior):

load averages: 48.33, 47.83, 47.75
and top
1059 root            60  52    0  9912K  1236K RUN     7    ??? 788.96% nfsd

Thank you very much
Radek
