I'm trying to create an array, /dev/md2 , out of 4 hard drives. I am able to create it with mdadm, but I am getting a strange line when I do a, mdadm --detail /dev/md2:

I formatted each drive with one partition that spans the entire drive of type fd (linux raid autodetect)

Here is my creation line:

mdadm -v --create /dev/md2 --chunk=128 --level=5 --raid-devices=4 /dev/sd{a,b,c,d}1

Here is my mdadm --detail /dev/md2

mdadm --detail /dev/md2
/dev/md2:

4 8 49 4 active sync /dev/sdd1

---------------

The line in question is:
2 0 0 140693960 removed

What is that line? Its a fresh array and I haven't removed a device from it.

Any ideas?

Thanks.
 
I'm pretty sure that is because the raid is still syncing, though i'm not 100% on that.
