So your root is /dev/mapper/house-system which itself sits on top of device 254:11 which is ST3120811AS_6PT0TQ9P-part1 which sits on top of ST31000528AS_9VP2VWC2 which *is* multpath device. In retrospect "dmsetup ls --tree" had made it easier probably :)
So you do use multipath for your root. I have no idea why. Could you please show /etc/multipath.conf (probably as "grep -v '^#' to strip off comments).
I don't think so,

My root sits on 254:12, which is independent of ST31000528AS_9VP2VWC2; the latter is a disk with a btrfs partition mounted on /home/petros/mnt. dmsetup table still indicates that no device is multipath-enabled (I'm reading the numbers after the word multipath and they're <=1), also multipathd is not running. The weird thing is that a file /etc/multipath/wwids now exists, which didn't exist yesterday. Its contents are:
