WIP: Dell T7910 with Proxmox VE 7.0 and External Ceph Cluster

While for my virtualisation needs I am firmly in the Red Hat camp, an article in ix 9/2021 piqued my interest.

Since I was on a week of ‘staycation’ and the T7910 was not in use, I decided to test Proxmox VE 7.0 on a Dell Precision T7910 tying in my existing Ceph Nautilus storage for both RBD and CephFS use.

more NVMe storage

Added this to my server:

  • Supermicro 2-Port NVme HBA AOC-SLG3-2M2-O
  • 1000GB Samsung 960 Evo M.2 2280 NVMe PCIe 3.0 x4 32Gb/s 3D-NAND TLC Toggle

My braindump follows.

set fan thresholds on my Super Micro H11DSi-NT

The Super Micro remote management webUI is nice and even offers KVM with HTML5. But I much prefer using vendor agnostic IPMI directly instead of a vendor specific tool like iDRAC, iLO, etc.

These are my notes on setting fan thresholds via IPMI for my H11DSi-NT motherboard.

TPM to feed random number generator

One of the uses of a TPM is to feed /dev/random on your linux box. I will not go into the political implications of TPM.

See also Matt Domsch’s blog.

Those still running RHEL5/CentOS5, be sure to have rng-utils-2.0-4 or later and kernel-2.6.18-238.el5 or later.

Some of the following steps are specific to my HP ProLiant MicroServer, but most will apply to any modern linux and HW (one would prefer the TPM to be an integral part of the motherboard as opposed to a module).

git server setup

For the last decade, I have been using cvs at home to have version control over documents (mostly LaTeX and config files). The original cvs server has been since migrated to a virtual machine.
