[Lustre-discuss] couldn't create proc entry sys/lnet/stats

[Ramiro Alba Queipo]

Hello Guy:

I am using Ubuntu 8.04 with lustre packages from
http://www.pdsi-scidac.org/repository/ubuntu/pool/hardy/lustre/

that means kernel 2.6.22.19 and lustre 6.5.1 and I have the same
warning. Which linux distribution are you working with?

Regards,

Ramiro
