Ooops... You know what it is : the more you focus on a problem, the
less you can see solutions floating around...
I had mdadm-1.2 installed, and of course did not think about
upgrading... I will test this asap.
This will avoid me to code a byte reordering program... Thanks Neil !
BTW : I did not see this feature in the kernel code, and after a quick
look at mdadm source, seems to be implemented in
super0.c:super0_swap_endian(). Is there any prerequisite regarding the
kernel version for this to work ?
Thanks again Neil, I am really impressed by your patience answering
dummy questions...
Regards,
