May 4, 20224 yr My two SSDs I'm using as cache are mismatched sizes. I *think* from what I've read this means that they aren't protected, is that right? Is the only way (apart from a backup script) to have them the same size in an array, or does btrfs do something that I don't understand?
May 4, 20224 yr Community Expert Solution It depends on the BTRFS profile they are set to use. The default is raid1 and that means they are protected, but the usable space is only that of the smaller device.

I can't find them for some reason?
