Created attachment 1297481 [details] output of reproducer script Description of problem: When you load or present new tapes to the system and uevent is generated for those devices the systemd-udevd does not create the /dev/tape/by-id always. It's not happening all the times but is quite easily reproducible with scsi_debug Version-Release number of selected component (if applicable): 7.3 How reproducible: presenting scsi tapes to the system Steps to Reproduce: 1). for ((i=0; i<30; i++)); do modprobe scsi_debug ptype=1 add_host=2; sleep 5 ; ll -r /dev/tape/ ; modprobe -r scsi_debug ; done 2) check the result of the ls. You should have 4 symlinks there, to st0 nst0 st1 and nst1 as you are loading 2 tapes. Actual results: The symlinks are not created allways. Expected results: The symlinks are created allways. Additional info: When you map the tape and the symlinks are not created, you can fix it by running udevadm trigger. Attaching journalctl -f with logs from systemd-udevd in debug mode.
