Hi,
The mdadm.conf in the initrd image contains the correct devices. I.e.
the contents of mdadm.conf in initrd are the output of
mdadm --detail --scan
ARRAY /dev/md0 metadata=1.2 name=mercury:0
UUID=60ea870e:029dcf99:eaae356e:f1c12085
ARRAY /dev/md1 metadata=1.2 name=mercury:1
UUID=d89a52ed:0247f2e8:5edf5d09:21e7fa48
However, the problem remains. That is when booting, the system dumps
into initramfs shell with the raid array in an inactive state. I have
to manually stop the array and then reassemble.
mdadm --manage --stop /dev/md1
mdadm --assemble /dev/md1 /dev/sde1 /dev/md0
At the point, I am able to continue booting and everything is fine after.
Here are the contents of /proc/mdstat from the initrd shell before
reassembling the array.
md1 : inactive sde1[2](S)
976639672 blocks super 1.2
md0 : active linear sdb1[0] sdc1[1]
976770537 blocks super 1.2 0k rounding
unused devices: <none>
It just seems to me that it is not possible to mix md devices and sata
devices for new arrays.
Regards,
Jivko
