[Bug 531240] Re: breaking raid: root raid_member opened as luks

[ceg]

I got the beginning with
dd if=/dev/sdc7 of=raid-part-head bs=1M count=1


Fdisk etc. output with various units and "block sizes" but never stating the actual unit sizes is a mess.

#blockdev --report /dev/sdc7
RO    RA   SSZ   BSZ   StartSec            Size   Device
rw   256   512   512  195896673     19757090304   /dev/sdc7

#blockdev --getsize /dev/sdc7
38588067

Finaly this got me hopefully the last 1MB from the partition.

#dd if=/dev/sdc7 of=raid-part-tail bs=512 skip=38586019
2048+0 Datensätze ein
2048+0 Datensätze aus
1048576 Bytes (1,0 MB)

Note:
I noticed the fdisk output added "+" to to the size column of the partition (what ever that means), it being an odd number, and these "Notes_on_dd_and_Odd_Sized_Disks" (last sector missing with linux):
