[Lustre-discuss] Lustre installation and configuration problems

Tue Jun 16 09:36:32 PDT 2009

I think lconf and lmc went away with Lustre 1.6.  Are you sure you are 
looking at the 1.8 manual, and not directions for 1.4?

/usr/sbin/lctl should be in the lustre-<version> RPM.  Do a:
# rpm -q -l lustre-1.8.0-2.6.18_92.1.17.el5_lustre.1.8.0smp

Do make sure the modules are installed in the right place:
# cd /lib/modules/`uname -r`
# find . | grep lustre.ko

If it shows up, then do:
# lustre_rmmod
# depmod
and try again.

Otherwise, figure out where your modules are installed:
# uname -r
# cd /lib/modules
# find . | grep lustre.ko

You can also double-check the NID.  On the MSD server, do
# lctl list_nids

Should show 10.0.0.42 at tcp0
