Hi
I have an array with two 3TB disk, one data and one parity, and cache - 128GB SSD. Disk are encrypted (data + cache). Data disk is now marked as disabled and I want to replace it. My plan was to increase array size to 4TB per disk in first step. As I understand documentation (Storage Management | Unraid Docs https://docs.unraid.net/unraid-os/manual/storage-management/#parity-swap) and some threads on forum I should first change/swap parity disk. So please confirm:
1. I should stop array, shutdwon unraid
2. Insert new disk
3. Start unraid, add new, bigger disk to array, format it
4. Copy parity to new disk (there should be some new operation in Main -> Array Operation -> Copy)
5. After parity copying is done shutdown unraid
6. Remove old parity disk, remove old data disk, insert new data disk
7. Start unraid, include new disk in array
8. Rebuild array
I should remove data disc - disabled now in 6 step or after step 8? Does encryption affects somehow whole process (excluding extra time for encpryption), bigger risk of failure while replacing or need an extra step? As I understand documentation encryption should be transparent so no extra risk. Please confirm.
