Seems to work perfectly. I didnt know that the parity disk was able to just change place with the datadisk without problem. I did as you said, new config, assigned cache-disks, assigned old parity as datadisk, and the new 8TB disk as parity. Everything booted up and so far I havent noticed any glitches at all. Parity is rebuilding, and swapping the datadisk tomorrow to the new 6TB disk shouldnt be a problem. Thankyou very much for your help.

Data disk is dead and need to be replaced. So I want to replace both disks. 8TB for the parity disk and 6TB for the data-disk. In what order shall I do the replacement?

The Data DIsk is marked as "Disabled". It is reused old disks that are going to be replaced anyway with new Toshiba NAS N300 drives. I havent even concidered if the datadisk is possible to get working again since it is such an old disk. I attached the diagnostics anyway if that helps. iplast-diagnostics-20250815-1029.zip

Hello. I am sorry if my question already have been answered earlier in this forum, but I have done some searches and havent found a specific post that matches. I have a small Unraid-system just to use the Docker-functionality and have reused two 4TB drives and added two SSD 512GB as cache. So, my setup is one 4TB parity and one 4TB datadisk plus mirrored cache-disks och 512GB. The plan was ofcause to add more disks but that never happened since I dont need much space. Now the data-disk hade gone down permanently and I am going to change the parity to a new 8TB disk and the datadisk to a 6TB. What is the best way of doing this since right now I am running only from the parity disk. Shall I add the 8TB first to the 2nd parity slot and let it sync up and then add the 6TB datadisk? Im asking just because I am on a thin line here with only one parity disk working at the moment. There is no room for error. :) I hope I will get this sorted out before I loose the parity disk too. ;) I am running Unraid 6.12.13. /Fredrik
