gmirror: how to make your system reboot
Hi,
shouldn't there be a failsafe to not be able to destroy the
gmirror as long as it is still in use like mounted?
1. create a gmirror with n>=1 disks
2. newfs the gmirror device
3. mount the gmirror device
4. remove all disks from the gmirror
5. system reboots (gmirror gone but still mounted)
nudel# gmirror status
nudel# gmirror label -b prefer test /dev/ada1p2
nudel# newfs /dev/mirror/test
/dev/mirror/test: 4096.0MB (8388600 sectors) block size 32768,
fragment size 4096
using 6 cylinder groups of 740.00MB, 23680 blks, 47360 inodes.
super-block backups (for fsck -b #) at:
192, 1515712, 3031232, 4546752, 6062272, 7577792
nudel# mount /dev/mirror/test /mnt/tmp
nudel# gmirror remove test ada1p2
<reboot>

I'm just having remote access right now to the system so I'm not able
to provide any dumps but the system instantly reboots.
