Since it kept mixing up ad6 for ad6s1 I was trying to save a sector in
the label for the meta-data.. stupid.. I know.
I would think I could do this: ( this is what you mean correct? )
files# diskinfo ad4
ad4 512 160041885696 312581808 310101 16 63
sector size is 312581808 so make slice one sector smaller.
files# ( echo "p 1 165 63 312581807"; echo "a 1" ) | fdisk -v -f- -i /dev/a=
d4
files# ( echo "p 1 165 63 312581807"; echo "a 1" ) | fdisk -v -f- -i /dev/a=
d6
files# fdisk -s ad4
/dev/ad4: 310101 cyl 16 hd 63 sec
Part Start Size Type Flags
1: 63 312581745 0xa5 0x80
files# fdisk -s ad6
/dev/ad6: 310101 cyl 16 hd 63 sec

ad2s2

ad6s1
So whats going on?? It's like gmirror cant decide whether the meta is
for provider ad6 or ad6s1. It also does not matter order I bring the
mirror up in. If I start with ad6 then it is ad4 that has the issues.
Please Advise...
I shouldnt have to hardcode the provider name correct?
Thanks for your previous quick response! :)
Brent.
