Thanks Kevin..<br><br>I am referring to 1.8 manual, but I was also referring to HowTo page on

<a href="http://wiki.lustre.org/index.php/Lustre_Howto#Using_Supplied_Configuration_Tools">http://wiki.lustre.org/index.php/Lustre_Howto#Using_Supplied_Configuration_Tools</a>

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?<br>
<br>
/usr/sbin/lctl should be in the lustre-<version> RPM. Do a:<br>
# rpm -q -l lustre-1.8.0-2.6.18_92.1.17.el5_lustre.1.8.0smp<br>
<br>
<br>
Do make sure the modules are installed in the right place:<br>
# cd /lib/modules/`uname -r`<br>
# find . | grep lustre.ko<br>
<br>
If it shows up, then do:<br>
# lustre_rmmod<br>
# depmod<br>
and try again.<br>
<br>
Otherwise, figure out where your modules are installed:<br>
# uname -r<br>
# cd /lib/modules<br>
# find . | grep lustre.ko<br>
<br>
<br>
You can also double-check the NID. On the MSD server, do<br>
# lctl list_nids<br>
<br>
Should show 10.0.0.42@tcp0<br>

Thanks for the update Sheila. I am using manual for Lustre 1.8 (May-09).<br>
<br>
Arden, as per the 1.8 manual:<br>
--- ---<br>
Install the kernel, modules and ldiskfs packages.<br>
Use the rpm -ivh command to install the kernel, module and ldiskfs<br>
packages. For example:<br>
$ rpm -ivh kernel-lustre-smp-<ver> \<br>
kernel-ib-<ver> \<br>
lustre-modules-<ver> \<br>
lustre-ldiskfs-<ver><br>
c. Install the utilities/userspace packages.<br>
Use the rpm -ivh command to install the utilities packages. For example:<br>
$ rpm -ivh lustre-<ver><br>
d. Install the e2fsprogs package.<br>
Use the rpm -i command to install the e2fsprogs package. For example:<br>
$ rpm -i e2fsprogs-<ver><br>
If you want to add any optional packages to your Lustre file system, install them<br>
now.<br>
4. Verify that the boot loader (grub.conf or lilo.conf) has<br>
--- ---<br>
I followed the same order.<br>
<br>
<br>
The lconf and lmc are not available on my system. I am not sure what are they and when will I need it. I continued to explore other things in lustre and have created MDS and OST mount points on the same system. I have installed lustre client on a separate machine and when I tried to mount lustre MGS on it, I received following error:<br>
<br>
--- ---<br>
[root@localhost ~]# mount -t lustre 10.0.0.42@tcp0:/lustre /mnt/lustre<br>
mount.lustre: mount 10.0.0.42@tcp0:/lustre at /mnt/lustre failed: No such device<br>
Are the lustre modules loaded?<br>
Check /etc/modprobe.conf and /proc/filesystems<br>
Note 'alias lustre llite' should be removed from modprobe.conf<br>
--- ---<br>
<br>
<br>
The modprobe on client says, 'module lustre not found'. Any clues?<br>
<br>

I'm not clear on which kernel package you tried to install. There<br>
is pretty much a set order to install the packages from my<br>
understanding of the wording in the manual. From experience:<br>
<br>
rpm -ivh kernel-lustre-smp-2.6.18-92.1.17.el5_lustre.1.8.0.x86_64.rpm<br>
rpm -ivh lustre-1.8.0-2.6.18_92.1.17.el5_lustre.1.8.0smp.x86_64.rpm<br>
rpm -ivh<br>
lustre-ldiskfs-3.0.8-2.6.18_92.1.17.el5_lustre.1.8.0smp.x86_64.rpm<br>
rpm -ivh<br>
lustre-modules-1.8.0-2.6.18_92.1.17.el5_lustre.1.8.0smp.x86_64.rpm<br>
rpm -Uvh e2fsprogs-1.40.11.sun1-0redhat.rhel5.x86_64.rpm<br>
<br>
Hope that helps as that order has worked for me many times.<br>
