Last week I mentioned issues installing ZFS. I raised a bug report with Debian. A work around was posted for the installer issue and I have now got ZFS running on one of the storage servers. I haven't tried the other one yet but expect the same process will work on it.

Also last week I tried updating one of the Nvidia GPU machines to Debian Buster, their current release. It locks up while booting but can be accessed via ssh. From there I can install the Nvidia drivers. It will boot after that but the screen will only do 1024x768 resolution. I raised another bug for Debian. In the mean time I have gone back to running Debian Stretch which works fine.

CPDN announced on the 18th of June they were going to run the OpenIFS climate models. Normally they run 32 bit versions of the UK Met Office climate models. Since then I increased the memory in the Intel GPU machines to be able to run these. We're still waiting for these climate models to become available.

I've been working on one of two storage servers for the past two weeks. Its a hard disk based server in a 2U rack mount case. Hardware wise its all working, but the software is causing problems. I can't get ZFS installed on it. It fails to build. I've tried different Debian releases and all of them seem to be broken. I bought this one almost a year ago. It was intended to replace my current (tower case) server which has less drive bays, thus limited scope for expansion.

I mentioned two storage servers. The other one is a NVMe based one in a 1U rack mount case. Apart from the fans being really loud and annoying its hardware also works fine. It too needs to run ZFS so I have been trying to get the quieter one going first.

I have updated the Intel GPU machines to Debian Buster. Unfortunately Buster locks up on the Nvidia GPU machines and won't even give a logon prompt. Time to raise another bug with Debian.
