Setup problem with multiple mirrored devices



I have been trying to setup a series of mirrors of disk partitions
with mixed results. I have multiple ide disks on multiple ide
controllers. Each controller has only a master drive no slaves.

Ultimately I want to end up with something like:
gmroota -> ad0s1, ad0s2     [ mirrored ]
 M1         -> ad0s2, ad2s2     [ mirrored ]
 M2         -> ad4s1, ad6s1     [ mirrored ]
 M3         -> ad8s1, ad10s1   [ mirrored ]
 M4         -> ad12s1, ad14s1 [ mirrored ]
gmdata  -> M1, M2, M3, M4  [ concat ]

ad0 and ad2 same size disks sliced into two parts. ad0s1 and ad2s1 are
mirrored as gmroot. gmroot is bsdlabel partitioned: /, swap, var, tmp,
usr with the last partion 1 sector smaller then size of partition c: .
System boots fine.

ad0s2 and ad2s2 are bsdlabeled as one partition a: that is 1 sector
smaller then c:.
   bsdlabel -w ad0s2
   bsdlabel -w ad2s2
   bsdlabel -e ad0s2
   bsdlabel -e ad2s2
   gmirror label -v -b round-robin M1 ad0s2
   gmirror configure -a M1
   gmirror insert M1 ad2s2

This appears to work fine.

So then I move on to ad4 and ad6.
   fdisk -I ad4
   fdisk -I ad6
   bsdlabel -w ad4s1
   bsdlabel -w ad6s1
   bsdlabel -e ad6s1
   bsdlabel -e ad4s1
   gmirror label -v -b round-robin M2 ad4s1
   gmirror configure -a M2
   gmirror insert M2 ad6s1

gmirror picks up ad6 as the provider instead of ad6s1.

I have also tried

  fdisk  -I ad4; fdisk -I ad6
   gmirror label -v -b round-robin M2 ad4s1
   bsdlabel -w /dev/mirror/M2
   bsdlabel -e /dev/mirror/M2    # make a: on sector smaller then c:
   gmirror configure -a M2
   gmirror insert M2 ad6s1

Same results. ad6 is picked up a provider instead of ad6s1. What am I doing?

Seems like a meta-data problem. If I hardcode providers name with -h it works
as expected.

Please enlighten me to my errorrs!
