There are no logs - the device on which the logs were located is dead (the 
hard disk). After a reboot the box came back, but the hard disk does not 
appear in "show system boot-messages" - only ad0 (the flash) is recognized, 
ad1 is nowhere to be seen. The mirror-flash-on-disk has been removed and the 
whole RE will be replaced (hopefully soon). I have also removed 
mirror-flash-on-disk from all other Juniper boxes, seems like it is a really 
bad idea.
