I think it might have been due to using Void Linux. Their RPI images aren't the best honestly. I've switched to use a rack of Intel NUCs. They have 10g NICs attached via Thunderbolt and run as a Proxmox cluster. They serve my data mining/hording purposes for now. Two hold a postgres master/slave pair, but they only have 4TB nvme. I have one db server built out with 3x raidz drives that's getting a replica set and hope to have a second built out this month so I no longer have to depend on storage on the NUCs.

I should put the pi cluster back together at some point and try Kamal on them.
