Hm. I had tried a variant: a three-way mirror, with one device missing most of the time. The annoyance of that was that the pool complained most of the time that one device was missing. > Of course this requires an easily removable device. It also requires some other things, which I don't miss as constraints: - enough easily removable devices, and (more scarce) connection ports, for them to all be connected at once. I don't know what happens if you progressively resilver one mirror vdev after another, you'll have a "backup" that's skewed over time. - a pool made of mirror vdevs, not any other type. - removable devices that are disks (not tapes or blobs in a storage service or...) -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
