I know, that the /dev/sde block device doesn't exist anymore (cause I've stopped a piece of software, which simulated it), but I still see it in the lsblk output and in the /dev directory.



When I try the fdisk -l /dev/sde command I see a lot of errors in the syslog (below):

How should I tell Linux to remove the /dev/sde from its list of active block devices?
