Yes, i make
$graid5 configure -R  disk
this stops sync.
than I make  graid5 remove ...
and disclable foreach disck.

than i create new array, and all goes fine.
I rebooted server few times, all was fine.
I start coping my data, than power reboot happens...

in logs i see:

I start scan_ffs for raid ... it take much time ..
i will tell results...
but i think, this will not help , coz mounted(in reas-only) data is
damaged ....
