Add `zpool` flags to control the slot power to drives. This assumes
your SAS or NVMe enclosure supports slot power control via sysfs.
The new `--power` flag is added to `zpool offline|online|clear`:
zpool offline --power <pool> <device> Turn off device slot power
zpool online --power <pool> <device> Turn on device slot power
zpool clear --power <pool> [device] Turn on device slot power
If the ZPOOL_AUTO_POWER_ON_SLOT env var is set, then the '--power'
option is automatically implied for `zpool online` and `zpool clear`
and does not need to be passed.
zpool status also gets a --power option to print the slot power status.

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