Start with the run_085517.222865696_n4_tmpcephInitsh.log output and the artifacts under /artifacts/backup/ceph/squid/tls/cpu_arch=fips/run_1. Read the roachtest README and the linked investigation guidance, then use the Grafana run to determine why the backup/ceph/squid/tls test failed. Done means identifying and fixing the failure and confirming the roachtest passes.
