[Lustre-discuss] couldn''t create proc entry sys/lnet/stats
Hi all,
I''ve successfully built lustre 1.6.6 against vanilla 2.6.22 + OFED
1.3.1.
However, I am getting warning on installation of the lustre modules about being
unable to create /proc entries. Is this something to worry about? Apart from
the /proc warning, the client seems to be running quite happily.
(dmesg snip)
Lustre: OBD class driver, http://www.lustre.org/
Lustre Version: 1.6.6
Build Version:
1.6.6-19700101010000-PRISTINE-.scratch.lustre-1.6.6.linux-2.6.22.19-2.6.22.19-lustre-1.6.6

Lustre: Added LNI 172.31.108.225 at tcp1 [8/256]
Lustre: Added LNI 172.31.117.154 at tcp2 [8/256]
Lustre: Accept secure, port 988
LustreError: 3354:0:(router_proc.c:1013:lnet_proc_init()) couldn''t
create proc

Cheers,

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?
