Public bug reported:

Binary package hint: dmraid

Hello there,

Some months ago I used Windows Vista to create a RAID 1 array out of two
300GB SATA HDDs. Meanwhile I switched to linux (ubuntu 9.04 currently)
and want to have access to the "mirror" raid array. To do this I got
dmraid, but not all partitions get recognized by it. There are 3 primary
partitions and one extendet partitions which contains 3 more logical
ones (all formated with NTFS, but I think this should not matter, should
it?) - "fdisk -l" comes up with:

Disk /dev/sdb: 300.0 GB, 300069052416 bytes
255 heads, 63 sectors/track, 36481 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x899097b3

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1       18249   146577404    7  HPFS/NTFS

/dev/sdb7           30360       36482    49173504    7  HPFS/NTFS

Disk /dev/sdc: 300.0 GB, 300069052416 bytes
255 heads, 63 sectors/track, 36481 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x899097b3

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1   *           1       18249   146577404    7  HPFS/NTFS
/dev/sdc2           18249       22073    30720000    7  HPFS/NTFS
/dev/sdc3           22073       24623    20480000    7  HPFS/NTFS
/dev/sdc4           24623       36482    95256576    f  W95 Ext'd (LBA)
/dev/sdc5           24623       28447    30720000    7  HPFS/NTFS
/dev/sdc6           28447       30360    15360000    7  HPFS/NTFS
/dev/sdc7           30360       36482    49173504    7  HPFS/NTFS

Now if I try to discover the partitions with "dmaraid -ay", I get the
following:

# sudo dmraid -ay
RAID set "isw_dbbdjdbeie_Volume_0" already active
ERROR: dos: partition address past end of RAID device
RAID set "isw_dbbdjdbeie_Volume_01" already active
RAID set "isw_dbbdjdbeie_Volume_02" already active
RAID set "isw_dbbdjdbeie_Volume_03" already active

Some time ago there was already a bug, resulting in the same message
("ERROR: dos: partition address past end of RAID device"), which was
related to some kind of offset problems, but this should be fixed says
the correspondig bug report discussion.

 I tried with different versions of dmraid (even the unstable
1.0.0.rc15-8 version or older 1.0.0.rc14 versions) and asked in ubuntu
forums to get help - unfortunately, no luck so far and thus I consider
it a bug.

To give a bit more output (dmraid -ay -dddd -vvvv):
