Hi mailing list,
On my old
model name : Intel(R) Atom(TM) CPU 330 @ 1.60GHz
I'm currently seeing a resync speed of around 200MB/s!
~ $ cat /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
md0 : active raid6 sdg1[0] sde1[7] sdh1[8] sdf1[5] sdc1[3] sdd1[4] sdb1[9]
9751756800 blocks super 1.2 level 6, 64k chunk, algorithm 2
[7/7] [UUUUUUU]
[======>..............] check = 32.6% (636923520/1950351360)
finish=111.2min speed=196740K/sec
unused devices: <none>
This ia almost 10 times higher than what I used to see on 3.2 and
earlier. What's that about? The array is a 7 drive RAID6:
