30 * Functions to convert between a list of vdevs and an nvlist representing the
31 * configuration. Each entry in the list can be one of:
34 * disk=(path=..., devid=...)
43 * While the underlying implementation supports it, group vdevs cannot contain
44 * other group vdevs. All userland verification of devices is contained within
45 * this file. If successful, the nvlist returned can be passed directly to the
46 * kernel; we've done as much verification as possible in userland.
48 * Hot spares are a special case, and passed down as an array of disk vdevs, at
49 * the same level as the root of the vdev tree.
51 * The only function exported by this file is 'make_root_vdev'. The
52 * function performs several passes:
54 * 1. Construct the vdev specification. Performs syntax validation and
55 * makes sure each device is valid.
56 * 2. Check for devices in use. Using libdiskmgt, makes sure that no
57 * devices are also in use. Some can be overridden using the 'force'
58 * flag, others cannot.
59 * 3. Check for replication errors if the 'force' flag is not specified.
60 * validates that the replication level is consistent across the
62 * 4. Call libzfs to label any whole disks with an EFI label.
