FUCKUP.fail: Infrastructure failures, traced
A case archive follows real-world infrastructure failures from their first symptoms through evidence and troubleshooting.
- For
- IT administrators troubleshooting virtualized infrastructure
- Worth noticing
- Cases include concrete telemetry and commands; one Paperless workaround sets certificate verification to false in a home test environment.
Field notes
Each entry is organized around a symptom, what made it misleading, and the diagnostic evidence, rather than a generic fix list. The visible cases name concrete systems and measurements: Proxmox reports 7.71 of 8 GiB used while the Linux guest reports 6.4 GiB available, and another investigation follows connectivity failures after a host migration toward the network switch. A separate Nextcloud/Paperless entry documents disabling certificate verification in a home test environment, a workaround readers should treat with care.
