RAID5 Problem / rebuild startet nicht

Hallo Liste / Leute,

Ich glaub ich hab Mist gebaut ... Nach einem Stromausfall war mein RAID5 
"weg". (6 Disks, kein Spare) Der Versuch, das wieder zusammenzusetzen 
schlug fehl.

root@openmediavault:~# mdadm --stop /dev/md127
mdadm: stopped /dev/md127
root@openmediavault:~# mdadm --assemble --force --verbose /dev/md127 
/dev/sd[bcdefg]
mdadm: looking for devices for /dev/md127
mdadm: /dev/sdb is identified as a member of /dev/md127, slot 0.
mdadm: /dev/sdc is identified as a member of /dev/md127, slot 5.
mdadm: /dev/sdd is identified as a member of /dev/md127, slot 4.
mdadm: /dev/sde is identified as a member of /dev/md127, slot 3.
mdadm: /dev/sdf is identified as a member of /dev/md127, slot 1.
mdadm: /dev/sdg is identified as a member of /dev/md127, slot 2.
mdadm: added /dev/sdf to /dev/md127 as 1
mdadm: added /dev/sdg to /dev/md127 as 2
mdadm: added /dev/sde to /dev/md127 as 3
mdadm: added /dev/sdd to /dev/md127 as 4
mdadm: added /dev/sdc to /dev/md127 as 5
mdadm: added /dev/sdb to /dev/md127 as 0
mdadm: /dev/md127 has been started with 5 drives (out of 6) and 1 
rebuilding.

Wie bekomme ich das RAID wieder zum laufen ? Der rebuild Prozess startet 
nicht ? Muss ich /dev/sdg noch mal entfernen und erneut hinzufügen ) 
(--remove / -add)
Danke für Eure Hilfe.
