/dev/sdb13 174706938 976768064 401030563+ fd Linux raid autodetect
The size of that partition is 802061126 sectors. From what i read - mdadm should have placed the actual superblock somewhere inbetween 128K and 64K to the very end. This is a raid0 array. The problem that i am facing is that i need to move the superblock on another partition/drive (sda13) which is currently shifted/spaced out (basically it shrunk and i need to expand it to the size of sdb13). I need to get the exact location/dimensions, a definite 1:1 (nothing extra or less). I have tried inspecting the partition in question with dd and xxd to inspect the start/end of the superblock - but it is somewhat misleading, i do not see any pattern of mdadm specific headers to be able to identify it. So far, i have only been able to locate the UUID (bytes are reversed: 7c6afc87 it stored as 87fc6a7c) - but still cannot make out either the end or the start of mdadm headers.
Perhaps someone can point me in the right direction?
