smartctl reports every disk behind a PERC/MegaRAID controller as /dev/bus/0 with type megaraid,N; the helper named a drive by its path alone, so all of VDNT-Docker02's and Docker03's disks read as one drive "0", each overwriting the last. The slot is now part of the name (bus0-megaraid3), and Steward gives a repeated name an ordinal so two drives never share a series. Agent 1.20.1. fix(ansible): Steward stopping mid-run logs no traceback (#5749) The run's done-callback called exception() on a cancelled task, which raises; it now logs a run cut short by shutdown at INFO. A finished run's in-memory state is dropped by a timer rather than a sleeping task, which shutdown found still pending. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
