Hello,
i have a problem with my raid-array. I hope I'm at the right place (here
in this list) and that you can help me.
I've a simple question: how can I mark the "non-fresh" disks /dev/hde1
and /dev/hdg1 as "clean"? I didn't found anything at the web or in the
list archive. I'm using kernel 2.4.18 with builtin software-raid
support.
Regards,
Falk
