[Lustre-discuss] lustre 1.8.5 client failed to mount lustre

I got the following message for "lctl list_nids":
Opening /dev/lnet failed: No such device
Hint: the kerenel modules may not be loaded
IOC_LIBCFS_GET_NI error 19: No such device


It looks like the lunstre packet has been installed, but it does not hook with kernel correctly. Which part went wrong?

HI,

I am using luster 1.8.5. Server s are up and mounted without any problem. But client failed to mount the luster file system. I also did not see luster in /proc/filesystems.  Is there other rpm I needed to install on the client system?

The below is log from the client system:

[root at localhost client]# rpm -ivh lustre-client-modules-1.8.5-2.6.18_194.17.1.el5_lustre.1.8.5.i686.rpm
Preparing...                ########################################### [100%]

Are the lustre modules loaded?
Check /etc/modprobe.conf and /proc/filesystems
Note 'alias lustre llite' should be removed from modprobe.conf


[root at localhost client]# cat /etc/modprobe.conf
alias eth0 e1000e
alias eth1 e1000e
alias scsi_hostadapter ahci
options lnet networks=tcp


[root at localhost client]# cat /proc/filesystems | grep -i lustre

[root at localhost client]# rpm -qa | grep -i lustre
