After the host rebooted, truenas began mailing NOCOMM continuously. The UPS driver was fine throughout -- nut-driver@cyberpower stayed running and the CyberPower is still on USB here. What died was upsd, which publishes its state to truenas over the network: upsd: not listening on 192.168.1.10 port 3493 upsd: Fatal error: some listening interfaces were not available nut-server.service: Start request repeated too quickly upsd binds an explicit address, but the packaged unit only orders itself After=network.target, which is satisfied when networking STARTS rather than when an address exists. It tried to bind 11 seconds into boot, before NetworkManager had assigned the address, then burned all five default restart attempts inside one second, tripped the start limit and stayed dead. The shipped unit carries these two lines commented out, because upstream knows the case. network-online.target is the correct ordering; NetworkManager-wait-online is enabled here so it genuinely waits for addresses. StartLimitIntervalSec=0 and RestartSec are belt and braces: a slow address can no longer exhaust the attempts, and retries are spaced instead of hammered. truenas needs no change -- it is a correctly configured SLAVE that reconnected on its own, and its NUT config is regenerated from the middleware database anyway. Verified: upsd listening on both addresses, UPS OL at 100%, and truenas querying it again with zero failures since. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
