Problem mdadm / mdstat sata raid
Hi,
there is a problem with mount of sata raid 1 devices after
reboot. the partitions of the raid devices are randomly
mounted in different order.
(debian sarge amd64 RAID.)
Why are the order of the partions in the mdstat different?
Installed software are mdadm and amd64 kernel 2.6.8-11-amd64-k8?
No /etc/raid... no raiddev's are installed.

How can I define the order of device partition of the raid 1?
