Disk Sequence Sensitive Parity Disk

Which parity disk is sensitive to the data disks sequence? Is it always parity 2?

I want to replace my parity disks one by one with larger ones,

and while doing this change data disks sequence + add an empty slot,

So preferably do that when the parity that's sensitive to the data disks sequence is replaced and rebuilt.

OK, so it's parity 2.

 

Do I need new config? I thought to do all this changes in one array stop:

Data disks assignment changes (only sequence changes, no additions/removals/replaces), add new empty slot,

un-assign parity 2, assign the new disk as parity 2, and start the array to rebuild parity 2.

Parity 1 should remain valid.

To change any assignments you have to New Config.

 

New Config, unassign parity2, assign all other disks as you wish, but make sure all data disks you had before are assigned with none removed and none added. Parity1 will be valid, so check the parity is valid box and start the array.

 

Then, stop the array, assign parity2, start the array to begin rebuild of parity2.
