Hi! I just experienced this (minor) issue on a cluster of diskless systems having smartmontools 6.5+svn4324-1 (current version in stretch) installed.
The package is installed, because sometimes external harddisks are connected to them for running smart tests. "systemctl disable smartd" helped and prevents the red error message showing up in "journalctl -b", which would still be there if I had only removed the DEVICESCAN line from /etc/smartd.conf Regards, Thomas -- Thomas Arendsen Hein <tho...@intevation.de> - OpenPGP key: 0x5BB3F5195816791A https://blogs.intevation.de/thomas/ - https://intevation.de/~thomas/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrueck - AG Osnabrueck, HR B 18998 Geschaeftsfuehrer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner
