I'm just beginning to set things up, and I can't seem to get the cache drive to work.
Initially setting things up, I am able to select the drive. But then it gives me an 'unmountable: no file system' error. There is an option to format it, but it doesn't do anything. If I stop the array, the drive disappears. The only way I've gotten it to reappear again is by wiping the USB drive and starting it over again. But then I run into the same issue.
