Hi,
I wanted to upgrade my 1 parity setup of a 10 TB disk parity to a 2 parity setup with 16 TB Disks. The old parity disk I want to become a data disk after the parity swap procedure. I read the "https://wiki.unraid.net/The_parity_swap_procedure" article, but in my case I don't want to remove an old data disk.
I first inserted the new first 16 TB disk and precleared the disk. The array ia stopped. I unasigned my old 10 TB parity disk in the parity slot. I now assigend the new 16 TB disk in the first parity slot an got a blue indicator.
I now could start the array with "Start will start Parity-Sync and/or Data-Rebuild."
But like in the article I want the Copy button, with a statement indicating "Copy will copy the parity information to the new parity disk". When I assign the old 10 TB parity disk in a free data disk 7 slot both indicator went blue, but I only get the message "You may not add new disk(s) and also remove existing disk(s)." besides the start button and not the Copy button, with a statement indicating "Copy will copy the parity information to the new parity disk".
What am I doing wrong? I am using unraid 6.9.2. Should I only assign the new 16TB drive in the parity slot and do the data rebuild? I thought the copying procedure as described is faster? Thank you
