Odd read count during parity sync

[skoj]

Added a second parity disk to my server running 6.2.4. Shortly after the parity sync began I noticed that the # reads on one drive (disk 7) is exactly half that of all the other drives.

 

That doesn't seem right. Shouldn't all drives have roughly the same number of reads??

 

No errors in the console or logs. Nothing out of the ordinary aside from this.

That's normal and harmless.
