MD Raid6 appears not-degraded during initial resync just after creation:
md106 : active raid6 sdbv1[7] sdbr1[6] sdbq1[5] sdbp1[4] sdbo1[3]
sdbn1[2] sdbm1[1] sdbl1[0]
3144938496 blocks super 1.2 level 6, 512k chunk, algorithm 2
[8/8] [UUUUUUUU]
[======>..............] resync = 34.3% (179834012/524156416)
finish=54.3min speed=105637K/sec
and also from sys filesystem:
cat /sys/block/md106/md/degraded
0
(kernel 3.14.19)
Is this normal?

I'd say so.
(Re)syncing does not mean the array is degraded - everything you write
to the new array still has full redundancy immediately.
