Hi Neil,
As per http://www.spinics.net/lists/raid/msg39353.html, I also am
running into a recreation of RAID6 problem where the devices had
differing offsets due to addition to an array over time (growth) in
between mdadm upgrades... it seems I need a version of mdadm that
supports creating an array with varying data offsets per device.
As per suggested by you:
git clone git://neil.brown.name/mdadm -b data_offset
cd mdadm
make
But it failed:
{{{
In file included from super0.c:27:0:
sha1.h:29:22: fatal error: ansidecl.h: No such file or directory
compilation terminated.
}}}
full output:

Anything I need to do different? or is that git branch unstable atm?
