@maniacofmadness:matrix.orgManiac of MadnessThank you both for your responses! I'll have a look at what's contained in the default_config and pick what makes sense for my setup.14:24:26

@schnecfk:ruhr-uni-bochum.deCRTifiedNot necessarily nix-related, but is it possible to have some kind of failover for HA or at least zigbee2mqtt?13:40:01
@schnecfk:ruhr-uni-bochum.deCRTifiedMy sd-card died, and while I'm going to switch to an SSD now I'd love to look into making the system more resilient13:40:50
@hexa:lossy.network@hexa:lossy.networkHAHA basically13:41:41
@schnecfk:ruhr-uni-bochum.deCRTifiedSo you mean running two instances in parallel?13:42:20
@hexa:lossy.network@hexa:lossy.networkI guess two machines connected to a postgres cluster with their individual zigbee dongles13:42:22
@hexa:lossy.network@hexa:lossy.networkthough I'm not sure how that'd work, given they'd both like to write sensor data etc.13:42:47
@schnecfk:ruhr-uni-bochum.deCRTifiedWouldn't that result in a split brain for automation?13:43:02
@schnecfk:ruhr-uni-bochum.deCRTifiedSo everything would run twice 13:43:15
@hexa:lossy.network@hexa:lossy.networkyeah, I think that's not going to work13:43:19
@hexa:lossy.network@hexa:lossy.networkbasically set up k8s at home over 3 nodes and tada.wav13:43:28
@linus.heckemann:matrix.mayflower.deLinux HackermanI think this is a case where redundancy would cause more outages than it would prevent.13:43:39
@hexa:lossy.network@hexa:lossy.networkand connect your zigbee dongle via usb2ip on an anycast address13:43:52
@hexa:lossy.network@hexa:lossy.networksorry, I only have silly ideas today.13:44:01
@hexa:lossy.network@hexa:lossy.network
  1. don't run your HA on a Raspberry Pi

In reply to @hexa:lossy.network
sorry, I only have silly ideas today.
No problem, the idea on its own is probably a bad idea in the first place, given the state of sanity for home assistant 😀
13:44:56
@hexa:lossy.network@hexa:lossy.networkprobably, yeah13:45:08

I'm Using a rk3399 based RockPi4 😉
13:45:10
@hexa:lossy.network@hexa:lossy.networkneat13:45:14
@hexa:lossy.network@hexa:lossy.networkwith the nvme ssd mount?13:45:24
@schnecfk:ruhr-uni-bochum.deCRTifiedThat's also why I'm able to switch to an SSD as boot device now 13:45:27
@linus.heckemann:matrix.mayflower.deLinux Hackerman
  1. don't run your HA on an SD card
13:45:28
@hexa:lossy.network@hexa:lossy.network *
use the nvme ssd mount
13:45:38
@linus.heckemann:matrix.mayflower.deLinux HackermanSD cards are the worst13:45:38
@hexa:lossy.network@hexa:lossy.network * ~> use the nvme ssd mount 13:45:42
@schnecfk:ruhr-uni-bochum.deCRTifiedyes, bought that and it will be delivered today13:45:54
@hexa:lossy.network@hexa:lossy.networkusing an sd card for write intensive stuff is asking for trouble13:46:01
@hexa:lossy.network@hexa:lossy.networkdecoupling the controller/api and the frontend of homeautomation would be neat13:47:02
@hexa:lossy.network@hexa:lossy.networkthe controller could work in a consensus based fashion13:47:08

Yeah, I kind of knew that before
