Ofcourse.

The /etc/mdadm/mdadm.conf orginally looks like this:

DEVICE partitions
HOMEHOST <system>
ARRAY metadata=imsm UUID=5a17be47:4c36e982:9fd7aa92:6b23c688
ARRAY /dev/md/BootEnBackup container=5a17be47:4c36e982:9fd7aa92:6b23c688
member=0 UUID=9e351111:67d59d42:043dbdde:fe757582
ARRAY /dev/md/Data container=5a17be47:4c36e982:9fd7aa92:6b23c688
member=1 UUID=8a981b80:aa2c2f06:e4ec50a5:9045f323

Looks pretty much OK though... A mdadm -Es gives me the same numbers:

ARRAY metadata=imsm UUID=5a17be47:4c36e982:9fd7aa92:6b23c688
ARRAY /dev/md/BootEnBackup container=5a17be47:4c36e982:9fd7aa92:6b23c688
member=0 UUID=9e351111:67d59d42:043dbdde:fe757582
ARRAY /dev/md/Data container=5a17be47:4c36e982:9fd7aa92:6b23c688
member=1 UUID=8a981b80:aa2c2f06:e4ec50a5:9045f323

I think the DEVICE actually has to be "containers". Also, I'm not sure
if the gethostname() call implied by "<system>" will work in initrd.

I'll do some tests and see what works.

Sincerely,
