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? -Weilin You might try 'lustre_rmmod' following by 'modprobe –v lustre' - usually you will have useful error messages. The 'networks' option In /etc/modprobe.conf Is unnecessary – lnet will default to TCP. I would delete that line, as the syntax does not look correct.
