I’m also having a problem adding a 4th drive to my EX4 Raid 5. Last week I created a RAID 5 with 3 new WD Black 3TB drives. Today I installed the new drive (also a WD Black 3TB drive) and the EX4 did its thing to format it and get it ready for use. I can see it in the Storage > Disk Status on my dashboard, all drives show good and healthy. I’m running firmware 1.03.41 and have gone through the steps to Change RAID Mode. All through the process it warns that all data will be lost and there is no option to add an additional disk to the configuration. However, I do get an option to add it as a a spare drive but thats not what I want to accomplish.
I guess what I’m getting at is, has this issue been resolved?

Yes, got answers for two questions:
- RAID expansion:
We currently support three RAID migration modes:
1. JBOD to RAID 1
2. JBOD to RAID 5
3. RAID 1 to RAID 5
With the online raid migration, we do not support that yet. This is scheduled to be released in a firmware update in late January.
