Parity Swap Problems

Hello, So I have a massive dilema, I did a partity swap procedure and started the copy process

Once the copy process completed the array stopped and asked me to do the copy process again

So I did it again and same problem. What should I do now ?

Does this mean ive lose all data ?

    Very weird, each disk is being detected twice, with different letters, this is confusing Unraid, note parity is sdg, disk 2 sdf:

    I never seen this problem before but until it's resolved Unraid won't work correctly, maybe you're trying to use SAS multipath, Unraid doesn't support that, make sure there's only one cable from the HBA to the enclosure.

    That explains it, better to reboot after that, than start the parity swap procedure again.
