100daysofhomelab

It’s been a while… So, for Day 61 of #100daysofhomelab, I thought I should write up how to swap a disk in a Hetzner Dedicated Machine. I have a dedicated server I rent from Hetzner in Germany. It has an Xeon E5-1650 V2 processor (6 cores, 12 threads, 3.5Gz base, 3.9Gz turbo), 128Gb RAM, and a pretty impressive 15 6Tb HDD. All drives are hooked to a Mega RAID controller, but because I am running ProxMox, I left it in JBOD mode and set up the 15 drives in RAIDZ-2. All 15 drives are in a single pool (probably not ideal, but it works for me). Now and again, I get a message from ProxMox telling me about bad blocks… and every time it happens, I have to remember what to do to find the bad drive, report it to Hetzner, wait for them to replace the drive and then add it back to the pool… Today, it happened, so I thought I better document it, to help future me, and hopefully someone else out there… First, we need to find the drive in question. Usually, I’m my alerts, I get the Serial number of the drive causing problems. So, I ran the following command:

Looks like there is a new release for ESXi 8.0. Seems to be mostly a DPU patch. Anyone running ESXi with DPUs might need to look into this…

Day 60 of #100daysofhomelab and I have been sick for most of the last 2 weeks, so that’s why I haven’t been posting much… Today is going to be links only too…

• Updates on the 3CX Security Alert for Electron Windows App – and the next few links are all about it… I use 3CX at home… Luckily I don’t use the desktop app (Phone app and their PWA app, but not the desktop one). If you do, start reading!

Day 59 of #100daysofhomelab and Proxmox released 7.4 of their Virtual Environment. I have not upgraded any of my machines to it, just yet, but that’s the plan for the weekend. Other than that, some links:

Day 58 of #100daysofhomelab and today is mostly a retrospective of what I did over the last few days, with some links thrown in for good measure…

Given I am going to keep GodBoxV3 running Windows Server 2022 for the foreseeable future, I installed Veeam Availability Suite (through their NFR program) and got it to backup up my Hyper-V VMs, along with my ESXi VMs to both local and Backblaze B2 storage. So far, so good.

Day 57 of #100daysofhomelab and its a link dump for today:

Day 56 of #100daysofhomelab and I managed to fix some stuff with my TrueNAS box. There was lots of messing when it came to permissions, but it works now. Some speeds are below. Not quite getting the speeds I was expecting, but there I have not tweaked anything, yet… This is going from my MacBook Pro with a 10Gb adapter. The reads are quite good, but the writes… well, the HDDs are FASTER than the NVMe… No idea why… I did get a new card to add another 4 NVMe drives in… We’ll see what happens when that gets built.

Day 55 of #100daysofhomelab and it’s going to mostly link dump today… Still working on my TrueNAS stuff, hopefully, I can get a couple of blog posts about it soon enough… Anyway, on to the links.

Day 54 of #100daysofhomelab and it’s going to be a very quick one… My head is wrecked with TrueNAS… Swapped TrueNAS Core (FreeBSD) to TrueNAS Scale (Linux). Trying to get Resilio Sync to work on it, but getting permissions issues… It’s after 2 am here, so giving up for the moment, but hopefully, I can figure it out tomorrow… On a different note, I ordered a load of storage upgrades (Another Hyper M.2 x16 card, some new NVMe drives, and some other stuff) for GodBoxV3… More details soon…

Day 53 of #100daysofhomelab and It’s been a busy week… ish… I’ve been battling with Vertigo on and off this week, so haven’t don’t a lot. I did, however, fix some issues with the network, set up a proper failover WAN connection using SmoothWAN and my Quad 2.5Gb Box, and have started making major changes to GodBoxV3.
