Hi there,

I have a quick question about the dmraid. I do have two raid subsets on my
controller:

*[root at bitch mapper]# /sbin/dmraid -s*
*** Group superset isw_bbhcggffce
--> Active Subset
name   : isw_bbhcggffce_FFD
size   : 144597504
stride : 256
type   : stripe
status : ok
subsets: 0
devs   : 2
spares : 0
*** Group superset isw_cgjefhbgdc
--> Active Subset
name   : isw_cgjefhbgdc_BFD
size   : 976767232
stride : 128
type   : mirror
status : ok
subsets: 0
devs   : 2
spares : 0


isw_bbhcggffce_FFD is already configured properly as you can see
(isw_bbhcggffce_FFD1 is here):

* [root at bitch mapper]# /sbin/dmraid -ay -v*
RAID set "isw_bbhcggffce_FFD" already active
INFO: Activating GROUP RAID set "isw_bbhcggffce"
RAID set "isw_cgjefhbgdc_BFD" already active
INFO: Activating GROUP RAID set "isw_cgjefhbgdc"
RAID set "isw_bbhcggffce_FFD1" already active
INFO: Activating partition RAID set "isw_bbhcggffce_FFD1"

I tried to partition isw_cgjefhbgdc_BFD with fdisk (/sbin/fdisk
/dev/mapper/isw_cgjefhbgdc_BFD). I created a linux patition. I would now
expect it to be /dev/mapper/isw_cgjefhbgdc_BFD1 as it's shown in fdisk. But
it is not in place.

What am I doing wrong? Any ideas?

Thanks in advance,
Jan **
