patrickstigler Posted March 1, 2023 Share Posted March 1, 2023 Hi, I had some problems with a disk, so I fixed them and also added a bigger parity disk on the 2nd position (to move it later). My parity build is complete, so I removed the first parity disk and wanted to move the 2nd on the first position, but I haven't found a easy solution. Is it possible to basically just move it's position? how? Or does it even matter if my only parity drive stays on position 2? Quote Link to comment
JorgeB Posted March 1, 2023 Share Posted March 1, 2023 Parity must be re-synced if you move the disk. Quote Link to comment

The calculations used for parity1 and parity2 are different so the disks cannot simply be moved. If you want to move parity2 to the parity1 position then you would need to rebuild parity. The alternative is just to remove parity1 and run without it leaving parity2 in place Quote Link to comment
patrickstigler Posted March 1, 2023 Author Share Posted March 1, 2023 Ok thank you, I guess than I just need to remove the parity 2 - wipe it. And mount it as parity 1? No data will be lost, I hope :-D Quote Link to comment

patrickstigler Posted March 1, 2023 Author Share Posted March 1, 2023 So @itimpiI need to preclear it, or will a quick format do it? Quote Link to comment
apandey Posted March 1, 2023 Share Posted March 1, 2023 Since it's a parity drive, you don't need to pre clear or format. It will be completely overwritten as part of parity rebuild Quote Link to comment
patrickstigler Posted March 1, 2023 Author Share Posted March 1, 2023 (edited) But somehow I can't use it, can't remove the 2nd parity. *EDIT* I guess I have to use the "New Config" tool to get it to remove the Parity 2. Am I right? Or is there another way? Edited March 1, 2023 by patrickstigler Quote Link to comment
Solution trurl Posted March 1, 2023 Solution Share Posted March 1, 2023 You will have to New Config before it will let you reassign parity 2 1 Quote Link to comment
patrickstigler Posted March 1, 2023 Author Share Posted March 1, 2023 Ok, looks good. Thanks for the help Quote Link to comment
