A dump on a RAID5 vinum volume causes a freeze of the system. This happens at dump phase IV (dumping files). After this the system is not accessible by any key (No console switching, CTRL-ALT-DEL,...), only pressing RESET-Button or Power cycling helps. How-To-Repeat: build a raid5 vinum volume, for instance my config: (make diskslices with type vinum) # disklabel -e da1e (type vinum) # disklabel -e da2e (type vinum) # disklabel -e da3e (type vinum) (write a vinum config file) drive d1 device /dev/da1e drive d2 device /dev/da2e drive d3 device /dev/da3e volume raid plex org raid5 256k sd length 512m drive d1 sd length 512m drive d2 sd length 512m drive d3 (set it up) # vinum ->create vinum.cfg ->init -vw raid.p0 (this needs some time!) ->quit # newfs -v /dev/vinum/rraid # mkdir /mnt/raid # mount /dev/vinum/raid /mnt/raid (populate it) # cp -R /usr/share/doc/usd /mnt/raid # cd / # dump -0au -f /dev/nrsa0 Now you hear some hd activity, dump runs through its phases and when phase IV is reached, the system freezes.
