# uname -a; mdadm -V

mdadm - v1.5.0 - 22 Jan 2004
-----------------------------------
why the device is not started sync?
how can be an active "dirty, no-errors" raid 5 from 7 disk working with
5 disks?
and I can even mount /dev/md2!
what can I do in this case?
another realy strange thing with mdadm at all reboot we've got a
NewArray and a SparesMissing message for all raid device. why???
yours.
