Today's missing ZFS feature is most easily described by telling youabout the problem. Suppose that you have a redundant pool (okay, aredundant vdev) and one of the disks in it develops some bad sectorsthat can't be read. My current understanding is that this is not a'replace disk immediately' sign the way that write errors are, andthus can happen on otherwise healthy and usable disks.

(A persistent write error is a 'replace disk immediately' sign becauseit means that the
