Hi,
Munin uses the following command to get sensor-type information out of SMART-aware disks (e.g. temperature):
/usr/sbin/smartctl -A --nocheck=standby -d ata /dev/sda
This broke following an upgrade from v6.1.76 (as found in Debian 12) to v6.1.82 (as currently found in the proposed-updates repository for the next point release of Debian 12), with smartctl's now reporting:
smartctl 7.3 2022-02-28 r5338 [x86_64-linux-6.1.0-19-amd64] (local build) Copyright (C) 2002-22, Bruce Allen, Christian Franke, www.smartmontools.org
Device is in SLEEP mode, exit(2)
This happens on baremetal with 2 pairs of disks: - 2×ST4000VN008-2DR1 (sda, sdb) - 2×ST8000VN004-2M21 (sdc, sdd)
and that's an obvious lie with one pair doing system stuff and the other one doing media stuff.
This also happens within a Debian 12 QEMU VM running on a Debian 12 libvirt host, when using a SATA disk, which is what I've used to test various builds from the stable/linux-6.1.y branch and associated tags.
Building stable releases, I pinpointed it as a regression between v6.1.80 and v6.1.81, then pinpointed it to commit cf33e6ca12d8.
#regzbot introduced: v6.1.80..v6.1.81 #regzbot introduced: cf33e6ca12d8
This is also affecting v6.1.84 and v6.1.85 (released during my git bisect session).
Reported in Debian via: https://bugs.debian.org/1068675 (which included a trace with the distribution-provided v6.1.82 package).
Most recent trace, with v6.1.85 (mainline, using the distribution's config but without any patches):
