Re: [xcat-user] Problem deploying Dell C6420 from Ubuntu 18.04.05
And ... when using the 18.04.2 default diskless image, the system hangs about 5-6 seconds after boot. It doesn't even provide the Alt-F2 screen for using the shell. Sigh ...

Re: [xcat-user] Problem deploying Dell C6420 from Ubuntu 18.04.05
We had to let this sit for a while due to higher priority items. After the deployment stops, we can login to the shell in the console (Alt-F2). It appears at least one issue is that the initrd image isn't set up correctly, because megaraid_sas isn't loaded, and "modprobe megaraid_sas" fails with "module not found". The modprobe DOES work after running "depmod -a", but I would think that is something that should have been done before creating the image. I have no clue on how to proceed after the disk is recognized. The same thing happens with Ubuntu 18.04.2. At present I'm trying to create a diskless image for 18.04.2. During this phase I've gotten many messages like "ldd: ./linux-vdso.so.1: No such file or directory", but genimage appears to be doing something. I'll try packimage, then deploying. At present, I think Ubuntu 18.04 is very poorly supported by xCAT.

Re: [xcat-user] Problem deploying Dell C6420 from Ubuntu 18.04.05
Unfortunately, it appears xCAT breaks when trying to create a diskless image. That's probably another issue with 18.04.5. I think we'll just install 18.04.2 on the head node, and repeat all our configuration steps.

Re: [xcat-user] Problem deploying Dell C6420 from Ubuntu 18.04.05
Have you made any progress on this problem or are you still stuck? Can you deploy the node with a diskless image based on the same OS and see the disks from within the booted OS? The newest version of Ubuntu 18 that xCAT officially supports is 18.04.2. Several xCAT users have moved forward to 18.04.5, but there appear to be some issues with xCAT and Ubuntu 18.04.5 that are not well understood. I don't have access to this combination of hardware and OS, perhaps other members of the list have some experience with this combination. From: Calvin Dodge To: xcat-user@lists.sourceforge.net Date: 03/12/2021 06:41 PM Subject:[EXTERNAL] [xcat-user] Problem deploying Dell C6420 from Ubuntu 18.04.05 We are trying to deploy C6420 nodes with a diskfull image. The deployment hangs about about 9.5 seconds after the kernel recognizes the network and USB devices. Installment details: Head node was deployed using the live server ISO ubuntu-18.04.5-live-server-amd64.iso. The xcat-go install process created the /install/OS folder using that ISO. But we could not nodeset a node with that osimage name until we ran copycds manually with the regular server ISO ubuntu-18.04.5-server-amd64.iso. We've seen other strangenesses, like xCAT looking for a folder named "ubuntu-" when we tried to run genimage to create a diskless image Meanwhile, the nodes are using PERC controllers for storage, which uses the megaraid_sas kernel module. When we unpack the initrd used in the initial PXE load, we don't find the kernel module there. Could that be the source of our deployment hang? We see instructions on adding modules, but they don't appear to be relevant, because (1) Dell doesn't seem to provide a driver disk for the initial kernel (5.4.0-22), and (2) the "use RPM" approach is unlikely to work with a distribution that doesn't use RPMs. We CAN install Ubuntu on the node using the server ISO, so the necessary drivers are present there, at least. So it seems to be an xCAT issue. Has anyone else encountered this issue? If not, how can we diagnose it, beyond adding (an as yet unfound) megaraid_sas kernel module to the initial PXE initrd?
