Re: dmraid 1.0.0.rc14 ddf1 issue

Hi Nhan,

I get the following results with your metadata sample
(/dev/dm-29, /dev/dm-33 being sparse devices in my testbed with
your metadata on):

# dmraid -r
/dev/dm-29: ddf1, ".ddf1_disks", GROUP, ok, 486326272 sectors, data@ 0
/dev/dm-33: ddf1, ".ddf1_disks", GROUP, ok, 486326272 sectors, data@ 0

# dmraid -tay
ddf1_4c53492020202020808627c300000000346e1ff400000a28: 0 486326272 mirror core 2 131072 nosync 2 /dev/dm-29 0 /dev/dm-33 0

After activation:
# dmraid -s
*** Group superset .ddf1_disks
--> Active Subset
name   : ddf1_4c53492020202020808627c300000000346e1ff400000a28
size   : 486326272
stride : 128
type   : mirror
status : ok
subsets: 0
devs   : 2
spares : 0

The only device created is:
brw-rw---- 1 root disk 253, 34 19. Nov 11:22 /dev/mapper/ddf1_4c53492020202020808627c300000000346e1ff400000a28

This all looks fine.

I wonder, if you have another drive with DDF metadata on causing the
2 /dev/mapper/ devices ?

Ragards,
Heinz
