[UnRaid 6.12.10] [ZFS] Reorder Disk Position, add new Drivers and a 2nd Parity with Array of ZFS Pools

[skler]

I would like to reorder disks position, add a second parity disk and add few disks to the UnRaid Array. I have ZFS on all disks. 

 

I'm on UnRaid 6.2.10, with a single parity array. 

 

Is this the right (and faster) procedure? 

Step 1 - Rearrange disks

1. Stop array
2. Tools -> New Config (selecting the option to retain all current assignments)
3. Move disks 
4. Set Parity as Valid 
5. Commit Changes and Start the Array

 

Question 1: My ZFS Pools are called as diskX/share-name, for example: I've disk2/isos in Disk2. If I move this disk to 1 what will happens to the ZFS pool, will be renamed or Disk1 will have the disk2/isos pool? If it will not be renamed automatically, can I do it manually? 

Step 2 - Add second parity

1. Stop array
2. Add 2nd parity disk
3. Start the array and calculate the parity on Parity Disk 2

 

Question 2: This will check also pairty on Parity Disk 1? 

Question 3: When I will have two Parity Disks, the parity calculation will be done on both disks? In case have sense to merge Step 1 and Step 2 and calculate parity on both drivers? 

Step 3 - Add new disks

1. Preclear new disks
2. Stop array
3. Add new disk
4. Start array (without calculating parity)

 

Question 4: Will be parity2 valid adding new "zeroed" disks to the array?

The former.

Yes.

Yes, and they are different and not interchangeable.

Can I manually change it without breaking everything? 

 

So basically I can do step1-3 all together and start the parity check on everything

No, it's automatic, disk1 will always be a zpool called disk1.
