Mounting an internally installed disk on a laptop spins up all
disks connected to this machine via USB. And I try to prevent these
externally connected disks to spin up.
The behaviour, IIRC, started a few months ago on the previous F27 and
continues now on F28. Before that I don't remember this behaviour to
have happened.
I thought it was some smartd issue, and stopped this service
("/usr/bin/systemctl stop smartd.service") - to no avail: mounting the
internal disk still spins up the external ones.
The internal disk is identified by "smartctl -d test /dev/sda" like
so:
[ ... ]
/dev/sda: Device of type 'scsi' [SCSI] detected
/dev/sda [SAT]: Device open changed type from 'scsi' to 'sat'
/dev/sda [SAT]: Device of type 'sat' [ATA] opened
(On a side note: I'm astonished that a smartctl simple info flag is
changing some device type like shown above)
External disks are identified by a smartctl test like so:
One:
"[USB Sunplus]: Device of type 'usbsunplus' [ATA] detected"
the other one:
"[SAT]: Device of type 'sat' [ATA] detected"
Anyone an idea about where to start investigating this issue? Where
could such behaviour possibly be set up?
Thanks in anticipation.
