February 18, 20242 yr Recently, my single 500 GB SATA SSD btrfs cache drive (identified by Unraid as 'Cache') had a minor SMART error, so I upgraded by adding two 1 TB NVMe m.2 btrfs drives to the cache pool ('Cache2' and 'Cache3'). I then followed instructions to remove the original drive. Now I'm left with a Cache Pool that shows three slots, with only slots 2 and 3 populated. Like this: https://imgur.com/a/oAb1Xx6 I tried to move 'Cache2' to 'Cache', but Unraid reported that all data on the drive would be erased. Umm... that doesn't seem right! How can I tidy this up so that the two 1 TB drives are correctly seen as 'Cache' and 'Cache2' in a two-slot cache pool? Edited February 18, 20242 yr by Karyudo
February 18, 20242 yr Community Expert If you move both cache devices a slot up there should be no warning, if there is post a screenshot.
February 18, 20242 yr Author Ah! That's something I didn't try, of course, having been scared off by the warning when I moved the first. I'll give that a try. Thanks!
February 19, 20242 yr Community Expert Strange, I was pretty sure this still worked, but you can do this instead: unassign all pool devices start array, stop array reassign all pool devices, you can also change slots to 2 now start array, it will import the existing pool
