Problem with assembly after a drive replacement

Problem with assembly after a drive replacement

[michael]

I have a six drive raid 6 consisting of sdc1 through sdh1.

Recently sdg died and I replaced it using mdadm -f and mdadm -r.

When I was adding the drive back, I accidentally added /dev/sdg instead 
of /dev/sdg1.  So, I went through and did mdadm -f and mdadm -r to 
remove it.

I repartitioned the drive to give me /dev/sdg1 again and used mdadm -a 
to add it back.

The drives sync'ed and I thought all was well.  However, now at boot up, 
I get:

md2 : inactive sdf1[3](S) sdd1[1](S) sde1[2](S) sdh1[5](S) sdc1[0](S) 
sdg[6](S)
       2930306176 blocks

Looking through dmesg, I see it is trying to add sdg and not sdg1.

md: bind<sdg>
md: bind<sdc1>
md: bind<sdh1>
md: bind<sde1>
md: bind<sdd1>
md: bind<sdb1>
md: bind<sda1>
md: bind<sdf1>


I can assemble the array by hand and all is well.

mdadm --assemble /dev/md2 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 
/dev/sdg1  /dev/sdh1

How do I make it forget about /dev/sdg and assemble using sdg1?  I tried 
updating the super block minor at assemble time and that didn't seem to 
make a difference.

I am running Fedora 9 with kernel 2.6.25.14-108
