Mighty gurus! I have a mirror that I want to rebuild. Though there is
no data on the volume, and the volume is not mounted, I cannot blast
away the mirror because of one submirror that clings to life. It has a
disk in a Last Erred state and no amount of "metaoffline -f" "metadetach
-f" "metaclear" or anything else will let me destroy this mirror and
submirror. All errors return as "operation would result in no readable
submirrors" or "attempted to clear mirror with submirror(s) in invalid
state" or something to that effect to which I respond, in this case
only, "who cares?! Do what I want!"
I have even tried to replace the "Last Erred" disk with "metareplace -e
d3 c0t24d0s2" but that also fails. "metasync" does nothing Without
rebooting, what options are left? The mirror had 2 submirrors, I
removed one but I was still unable to kill the whole mirror because the
"Last Erred" one was hanging me up. I have listed the output from a
metastat command.
Thanks,
Brian
