Bug#589493: mdadm 3.1.2 fails to grow RAID 6 array - overflows when expanding number of drives in array

Package: mdadm
Version: 3.1.2-2
Severity: important
Mdadm fails when attempting to add a drive to the array. I believe this is a bug of which Neil Brown is aware and has fixed in code but not released. It is a critical
bug for anyone running RAID 5 or RAID 6 who needs to grow their array, which is in turn a critical function. It may not affect those running RAID 0 - 4.
