I think one of the drives on my zraid might be failing. The pool isn't being attached on boot, zfs-import-cache says "one or more devices is currently unavailable", but when I run `zpool import` everything says it's online.
So, one of the drives is taking Longer Than It Used To to wake up on reboot. Or, perhaps, the additional ram is just making bootup that much faster than it used to be? Maybe I just need to delay zfs startup? hm.
