Hello

I tried create one IMSM RAID10 with missing, found lots of "md: export_rdev(sde)" printed, anyone could help check it?

Steps I used:
mdadm -CR /dev/md0 /dev/sd[b-f] -n5 -e imsm
mdadm -CR /dev/md/Volume0 -l10 -n4 /dev/sd[b-d] missing

Version:
4.8.0-rc5
mdadm - v3.4-84-gbd1fd72 - 25th August 2016
