Furby8704 Posted December 6, 2020 Share Posted December 6, 2020 so i have 3 cages of 4 slots. 12 slots total. 1 parity x 11 drive data. i want to add a 2nd parity drive. so itll be 2 parity x 10 data. i will be replacing the smallest data with the 2nd parity to take its slot. what will be the best way to add the second parity drive??

Pbruce1 Posted January 20, 2021 Share Posted January 20, 2021 Bump. (I also would like to know best practices of adding a 2nd parity drive) Quote Link to comment

Pbruce1 Posted January 20, 2021 Share Posted January 20, 2021 Oh i see. No, i've got available slots, just want to ensure I add 2nd parity drive correctly (I cant find any official documentation to address this) Quote Link to comment

Sorry for bumping this old thread, but I have a question regarding adding a second parity. When Unraid starts to build the second, newly added parity drive, is the first one rebuild too? This would mean that for the time being there is no functioning parity drive? If another drive fails during this procedure, I'd be in big trouble? Quote Link to comment

So in theory there is a higher possibility of failing since it goes through more mechanical stress. But eventually I have to do a parity check anyway. Thank you! Quote Link to comment
