What does "kicking non-fresh partition from array" mean?

Hi all,

Can somebody tell me if some log warnings I'm seeing are worrisome? Does
"kicking non-fresh scsi/host4/bus0/target1/lun0/part1 from array!" refer to md4 or md6?

As you can see from cat /proc/mdstat, I have a failed removed drive in md6 -- which I am about to replace. Does this "kicking out" from the Kernel Warnings log refer to md4 or md6?

FROM KERNEL WARNINGS LOG:
I see this every time I reboot
