I should mention the WAL is on an NVME

I have a 3 node cluster and I replaced 3x8TB drives and the recovery/rebalance is going to take 20+ days and maxes out at 10MiB which seems exceptionally slow. I've changed all relevant parameters, though setting them at a global level doesn't have any effect. It does change when set at the...

Nevermind, found a really good article that explains this and how to avoid it https://www.percona.com/blog/2019/08/02/out-of-memory-killer-or-savior/.

Nice, I didn't know about that. Thank you. Having the extra isolation that VMs bring is a benefit as long as there aren't processor vulnerabilities to worry about.

I'm curious if there are any future plans to support MicroVMs in Proxmox? https://firecracker-microvm.github.io/ looks very promising for creating very low resource usage VMs (not containers) and is the technology backing AWS Fargate 1.4 without the Docker Engine as outlined in...
