3 drives fell out of Raid6 mdadm - rebuilding?

view story

http://serverfault.com – i had an mdadm raid6 array with 13x1TB drives. Within 10 minutes 3 of these drives fell out of the array... we assume bad cable to the controller card and replaced, however now we need to get the drives back into a working array. because md0 was marked as failed we removed the mdadm array and made a new md0 with the original 13 drives. 1 failed again during rebuild so we now have a degraded md0. The problem is that lvm does not see the array that exists within mdadm. Is there anything we can do to get our data back? $pvscan PV /dev/sda5 VG nasbox lvm2 [29.57 GiB / 0 free] Total: 1 (HowTos)
