When disklabel is run on a md without the full path name to the device a new device is created, even if the device name is silly. If the device is the 'c' device then the error message: WARNING: Driver mistake: repeat make_dev("md10c") is reported. If the md is detached the system crashes with the following error printed over and over: WARNING: Driver mistake: destroy_dev on 95/82 Part of the problem is caused by disklabel auto appending a 'c' onto the device name so md10c becomes md10cc, and then disk_clone() doesn't bother to check for that. Fix: Fix disk_clone() so that it does not try and [re]create devices that have bad names. How-To-Repeat: 1) Create a md. mdconfig -a -t swap -s 32m -u 10 2) run disklabel. disklabel md10c (note console output) 3) detach the md. (XXX crashes my local machine). mdconfig -d -u 10
