BigFam Posted September 4, 2021 Share Posted September 4, 2021 Hi, I created a RAID 0 cache pool using 2 new SSDs BTRFS formatted. One of the drives show SMART errors and will have to be RMA:ed. I have received a replacement drive. What is the procedure to replace one of the drives in this scenario. The forum posts I have found cover only older single drive cache pool scenarios. Is there a way to replace only one drive in this scenario or do I have to treat the RAID 0 cache pool as 1 disk and then re-create the pool using 1 old and 1 new disk? Quote Link to comment
Michael_P Posted September 4, 2021 Share Posted September 4, 2021 It's 1 disk as far as the OS is concerned, treat as such 1 Quote Link to comment

I guess it's a separate question but what would the procedure look like to replace 1 drive in a mirrored cache pool? Quote Link to comment
Michael_P Posted September 4, 2021 Share Posted September 4, 2021 Looks like in 6.9.2 the GUI method is broken, so treat it as a single drive or do it manually via the console Quote Link to comment
