Reracking and rewiring LMR site's three racks and three tape libraries. This includes network, storage, and servers.
Server infrastructure
Dave Brooks Electric
25 Nov 2024
I've been using Dave Brooks Electric for a few years now - since I bought a house in Staunton, VA. The amount of outright unusual work I've had done to get my own up to scratch for my three full racks, three tape libraries, and to get my 16kVA UPS installed is absurd. That's not including the 48kW generator that's in progress.
Full review in post!
FreeIPA - Install Replica Fails - Install Admin User During Configuring CA Server
28 Feb 2023
Can't create a new replica of an older FreeIPA server (v4.6.8 on c7) to a new FreeIPA server (v4.9 on f36 and v4.10 on f37). The error is during the `Configuring certificate server (pki-tomcatd)` phase.
Digital Archive Cooling
20 Jan 2021
Up until now I've been cooling the thermally (and physically) isolated server room from the rest of my house and using a large mini-split to keep it cool. However the mini-split has reached its limits; The room now has 9-10 kW of gear in it.

The network side of my rack redo is almost done. Once the two SRX650s on top are removed it'll be good to go.

Mirrors Are Back Up - Sorta
12 Dec 2018
My yum mirrors are back up and stable. Although they're 100% on my home infra atm. Long term I plan to use an OVH-Virgina set of VMs to act as caching proxies before hitting my home.
