X-List-Received-Date: Sat, 21 Jul 2007 12:31:16 -0000
I am trying to set up a RAID 10 data array using 12 identical 33gb scsi
disks. 2 are being kept for spares
First I set up a single slice on each disk using:
fdisk -I -1 /dev/da{0,1,2,3,4,5,6,7,8,9,10,11,12,13}
Then I set up the mirrors:
gmirror label -v -b round-robin dm0 /dev/da0 /dev/da7
gmirror label -v -b round-robin dm1 /dev/da1 /dev/da8
gmirror label -v -b round-robin dm2 /dev/da2 /dev/da9
gmirror label -v -b round-robin dm3 /dev/da3 /dev/da10
gmirror label -v -b round-robin dm4 /dev/da4 /dev/da11
gmirror label -v -b round-robin dm5 /dev/da5 /dev/da12
And finally the stripe:
gstripe label -s 524288 ds0 /dev/mirror/dm0 /dev/mirror/dm1 /dev/mirror/dm2
/dev/mirror/dm3 /dev/mirror/dm4 /dev/mirror/dm5
The gstatus is fine:
and the array is usable/mountable/newfs'able but I am concered by the warnings
in /var/log/messages:
Jul 21 08:03:56 db kernel: GEOM_MIRROR: Device mirror/dm0 launched (2/2).

Jul 21 08:06:58 db kernel: GEOM_STRIPE: Cannot add disk mirror/dm5c to ds0 (error=17).
And it's odd that I do not get it for device dm1 (da1/da8).
So, what am I doing wrong?
This is on 7.0-CURRENT amd64. Athlon X2 3600, 2GB ram

I would interpret this as follows:
gstripe takes dm0 and dm1 into its ds0...
When it sniffed at dm0c it saw, that it has the same meta data as dm0, which
results in error number (errno) 17 (EEXISTS /usr/include/errno.h)...
Resolution:
You should delete the fdisk meta data in the beginning (first 63 sectors) of
each disk for "cosmetic" reasons, because:
1. It is not used...
2. It creates unnecessary warnings...
:)

Ahhh, that was the basis of my confusion. I will try that!
