Hot Swap RAID5 4TB disks with 10TB
Hello Everyone, I have a RN214 4-Bay configured in RAID5. Disk1: Seagate IronWolf 6TB: Purchased 2020 Disk2: Seagate IronWolf 6TB: Purchased 2020 Disk3: Seagate IronWolf 4TB: Purchased 2016 ...
We do recommend making sure you have a backup, as the RAID array isn't redundant during resyncs, and the process does stress the disks.
The process is simple - hot swap disk 3 first, as it is showing signs of failure. The array will then resync in two steps (and the second step should expand your volume by 2 TB).
After the resync, hot swap disk 4. That will resync in three steps - the second step will expand your volume by another 2 TB, and the third will expand it by 4 TB.

Stephen,
I appreciate the fast response. Yes, I have a USB backup on the NAS. I'll follow-up upon completion.
Thank you,
