Yes, I faced your problem late last year. 

You need to prepare your new drive to match existing drive. If the other 3 are not partitioned, leave the new one unpartitioned. 

Then you have to force it into the array using mdadm tool. I know, I spent says avoiding force until Lennart advised to go that way.

Search the tlug old mail for that conversation. If you can't find it, I can look around for precise steps I used to get back up. On transit at the moment so just relying on memory.

I use parted or fdisk, I am not familiar with other tools. In the end,
what matters is that the partition(s) on the new drive match (equal
size or larger) the existing partitions.

You will then have to tell mdadm to use the new partitions. It will
not "just use them".

As Lennart asked; Show us the output of 'cat /proc/mdstat'. Also,
please share the output of:

parted /dev/sda print free
parted /dev/sdb print free
parted /dev/sdc print free
parted /dev/sdd print free
