Marks Rpi Cluster is back to running 24/7.
Fan Casualty
Last week I opened up the 2nd EC12 (Edge Cluster 12) so I could re-image the micro SD cards with Raspberry Pi OS 12. Yes I still use SD cards. While I had the back off I decided to give it a clean using a paint brush and air blower. I put it back together and got all the Pis going but there was a lot of fan noise when under load. After a bit of investigating I found one of the 80mm fans was not spinning.
There are two fans on the back of the EC12 to draw the warm air out of the case. The fans on the EC12 are only 10mm thick, normal fans are 20mm so I couldn't just swap it with a regular PC fan. I got in contact with Bitscope and went to their office this week and they gave me a couple of spare fans for free.
We're back to running on all 24 Pi4's now (each EC12 holds 12 Pis) and its running the Einstein@home BRP4 work.
Pi5s ordered
I've ordered a couple of additional EC12's with 24 x Pi5 8GB but Bitscope don't have firm dates for when they will get stock of the Pi5. They think it will be December 2023. It seems Raspberry Pi are limiting the current stock to hobbyists, so a limit of one per person. This gives Bitscope a bit of time to make changes to support the Pi5.
