The current target schema allows for vdev specification as follows:<target_device> <zpool name="mypool" is_root=true action="create"> <vdev redundancy="mirror"> <disk> <disk_name name="c0t0d0" name_type="ctd"/> ... </disk> <disk> <disk_name name="c0t0d1" name_type="ctd"/> ... </disk> <partition action="create" name="1" part_type="191"> <size val="5000mb" </partition> <partition action="create" name="2"> <size val="5000mb" </partition> <partition action="create" name="3"> <size val="5000mb" </partition> </vdev> </zpool> </target_device> </target> That is, when creating a 2 disk mirror and 3 partitions, how does one know which disk these partitions should be created on? There is no way of knowing as it currently stands. It just seems that instead of having disk/partition/slice elements embedded within vdev, it might be cleaner to simply have references in the vdev element to a disk/partition/slice name. Thus, doing away with needing to embed these elements within a vdev. It would look something like this: <target> <target_device> <zpool name="mypool" is_root=true action="create"> <vdev redundancy="mirror"> disk ="c0t0d0" disk ="c0t0d1" </vdev> </zpool> <disk> <disk_name name="c0t0d0" name_type="ctd"> <partition action="create" name="1" part_type="191"> <size val="5000mb" </partition> <partition action="create" name="2"> <size val="5000mb" </partition> <partition action="create" name="3"> <size val="5000mb" </partition> <disk> <disk_name name="c0t0d1" name_type="ctd"/> ... </disk> </target_device> </target> In the case a vdev is on a partition or a slice, the vdev specification would change to something like this (totally unrealistic but you get the idea): <vdev redundancy="mirror"> disk ="c0t0d0" slice = "0" disk ="c0t0d1" part = "3" </vdev> This would specify a mirror made from c0t0d0s0 and c0t0d1p3.
I'd be more comfortable if the references could be just full ctds or ctdp notation, rather than the split notation you're demonstrating here. Is there a reason not to do that?
