JP Posted April 12, 2020 Share Posted April 12, 2020 (edited) I was able to find documentation around how to replace your cache drive, however, I haven't found anything about how to move from a single cache to a dual cache setup. The reason I'm asking isn't because I technically plan to move to dual cache. I'm asking because I have the need to upgrade a desktop from a sata hdd to a ssd. My current cache in my unraid server is only 120 GB. I now see that 500 GB SSD go pretty cheap so my thought was to ultimately put this new 500 GB SD in my unraid server and leverage the old 120 GB cache drive for my desktop. Is it best to just follow the instructions I have or is it possibly easier to add the 500 GB drive in a dual cache setup and then sort of mimic that the other drive failed by removing it? I assume that one of the main points of going to dual cache is to provide redundancy so it should fall back to the single 500 GB cache just fine. I'm not sure if this make a difference, but I don't use MOVER. I do use DOCKERS, but no VM. Thanks for any guidance. Edited April 12, 2020 by JP update Quote Link to comment

Single cache has the option of XFS, multiple drive pools must be BTRFS, which requires formatting if you are XFS currently. If you insist on doing the drive failure thing, I'd make sure all your data was backed up before playing around to see if you could get it to work. Quote Link to comment
