Just installed a new node on the cluster, imaged just like the rest, but it was unable to mount lustre on boot. I tried to mount but got the following from dmesg:

I got the idea to run lctl ping from a post from someone with the same problem but over infinaband, we are using ethernet here. David -- Personally, I liked the university. They gave us money and facilities, we didn't have to produce anything! You've never been out of college! You don't know what it's like out there! I've worked in the private sector. They expect results. -Ray Ghostbusters _______________________________________________ Lustre-discuss mailing list Lustre-discuss@lists.lustre.org http://lists.lustre.org/mailman/listinfo/lustre-discuss
