My user was also in wheel so that should not be the problem. If your user is in operator it might be another matter though (new test): [simon@trillian:~] id uid=3D2000(simon) gid=3D2000(simon) groups=3D2000(simon), 0(wheel), 5(opera= tor), 68(dialer) [simon@trillian:~] ll /dev/mirror/sys0 crw-r----- 1 root operator 233, 3 Jan 6 11:23 /dev/mirror/sys0 [simon@trillian:~] gmirror stop sys0 Cannot destroy device sys0 (error=3D16). [simon@trillian:~] gmirror stop -f sys0 <hang> I don't have a console on the system right now but I assume it got unhappy that I pulled the device under the file system :-). I'm not really sure it is expected that you can do that when being in the operator group. --=20 Simon L.
