Caveats This information is valid at the time of writing (9.2-6 release). Currently, the installation of a cluster requires an ethernet interface, configured as “internalnet”. This is needed to generate a valid license file and associated certificates. Selecting Infiniband-only interfaces in the Bright Installer at the “Head node interfaces” step…
This article discusses deploying a NICE DCV server on Bright managed compute nodes.We recommend reviewing the excellent third-party NICE DCV upstream documentation, which is available here: NICE DCV (amazon.com) Before we start… This article doesn’t seek to replace the upstream documentation, rather details the integration with Bright Cluster Manager. This…
You can use the below instructions to configure kdump on a Bright managed cluster. These instructions should work on RHEL/CentOS 7 and 8. 1. Install required packages Install the kexec-tools in the software image:# yum install kexec-tools –installroot=/cm/images/<image-name> 2. Modify the software image Configure the software image to allow crashkernel…
Please note this article shouldn’t replace the need to contact your vendor for guidance on hardware issues. Here are some steps that may assist in resolving provisioning issues with SuperMicro BMCs. Is the system running the latest BMC firmware? Check the vendor website. Have you attempted a BMC reset? “ipmitool…
Important note: This process is generally used to recover a primary headnode from a failure state (filesystem corruption for example). This process doesn’t replace a good backup regime. If you intend to use this process to recover a primary headnode, we recommend contacting Bright Support first so we may assess…
*Please note:* Shorewall provides a NAT Masquerade rule that allows the compute nodes to access networks that are outside the cluster via the headnode. If you are okay with the compute nodes not having access to external networks or aren’t using the headnode as the default gateway for the compute…
During the installation of a bare metal headnode using the Bright Installation ISO written to a USB drive, you may find both the GUI and text installation modes fail or get stuck at the Rootfs step. The message from systemd on the server console may look like this: “A start…
Warning: These instructions may not be appropriate for all use cases. Please check the vendor release notes carefully before implementing. The Linux Kernel ABI compatibility appears to have been broken in newer Linux kernel releases.This appears to affect the kernels in SLES12 SP5, RHEL/CentOS 7.7 onwards, RHEL/Centos 8.1 onwards. There…
We recommend not using Rufus to create a bootable USB drive from the Bright ISO.Rufus changes the ISO Hybrid disk format which results in the Bright installer failing at the rootfs part of the Bright installer.
The “Failed to initialize NVML: Driver/library version mismatch?” error generally means the CUDA Driver is still running an older release that is incompatible with the CUDA toolkit version currently in use. Rebooting the compute nodes will generally resolve this issue. If you do not wish to reboot the compute node,…
