08a478a8e9 Provide a better explanation for the sizing of the boot partition, and
reduce the size of the partition in the example from 128 blocks to 94
blocks so it will end on a 128-block boundary.  Also remove the -b
option from the next example.

0c883cef45 Major GEOM MULTIPATH class rewrite:
- Improved locking and destruction process to fix crashes.
 - Improved "automatic" configuration method to make it consistent and safe
by reading metadata back from all specified paths after writing to one.
 - Added provider size check to reduce chance of ordering conflict with
other GEOM classes.
 - Added "manual" configuration method without using on-disk metadata.
 - Added "add" and "remove" commands to allow manage paths manually.
 - Failed paths are no longer dropped from geom, but only marked as FAIL
and excluded from I/O operations.
 - Automatically restore failed paths when all others paths are marked
as failed, for example, because of device-caused (not transport) errors.
 - Added "fail" and "restore" commands to manually control FAIL flag.
 - geom is now destroyed on last path disconnection.
 - Added optional Active/Active mode support. Unlike Active/Passive
mode, load evenly distributed between all working paths. If supported by
the device, it allows to significantly improve performance, utilizing
bandwidth of all paths. It is controlled by -A option during creation.
Disabled by default now.
 - Improved `status` and `list` commands output.

1f8c92e6fa Add support for creating GELI devices with older metadata version for use
with older FreeBSD versions:
- Add -V option to 'geli init' to specify version number. If no -V is given
  the most recent version is used.
- If -V is given don't allow to use features not supported by this version.
- Print version in 'geli list' output.
- Update manual page and add table describing which GELI version is
  supported by which FreeBSD version, so one can use it when preparing GELI
  device for older FreeBSD version.

6a0a87741b Don't use the whole free space when resizing partition to a larger size
on a disk with non zero stripesize (e.g. disks with 4k sector size)[1].
Also do not use automatic alignment when size is exactly specified, but
an alignment is not. Use automatic alignment only for case when user
omits both "-s" and "-a" options.

a6c21ef2d1 Use stripesize and stripeoffset in the automatic calculation of
partition offsets. If user requests specific alignment and
provider's stripesize is not zero, then use a least common multiple
from the stripesize and user specified value.
Also fix "gpart resize" implementation: do not try to align the partition
size, because the start offset may be not aligned. Instead align the
end offset and then calculate size. Also use stripesize and stripeoffset
for "gpart resize" command.

6c7e04f0f3 Some partitioning schemes want to have partitions that are aligned
with geometry. And they do recalculation of user specified parameters.
MBR, PC98, VTOC8, EBR schemes are doing that. For these schemes an
auto alignment feature (ie. gpart add -a alignment) would not work.
But it can work for GPT and BSD schemes. BSD scheme usualy is created
inside MBR, so we can use knowledge about offset of MBR partition to
calculate aligned values for BSD partitions.

Use "offset" attribute of the parent provider for better alignment.

89b172238a MFgraid/head:
Add new RAID GEOM class, that is going to replace ataraid(4) in supporting
various BIOS-based software RAIDs. Unlike ataraid(4) this implementation
does not depend on legacy ata(4) subsystem and can be used with any disk
drivers, including new CAM-based ones (ahci(4), siis(4), mvs(4), ata(4)
with `options ATA_CAM`). To make code more readable and extensible, this
implementation follows modular design, including core part and two sets
of modules, implementing support for different metadata formats and RAID
levels.

Support for such popular metadata formats is now implemented:
Intel, JMicron, NVIDIA, Promise (also used by AMD/ATI) and SiliconImage.

Such RAID levels are now supported:
RAID0, RAID1, RAID1E, RAID10, SINGLE, CONCAT.

For any all of these RAID levels and metadata formats this class supports
full cycle of volume operations: reading, writing, creation, deletion,
disk removal and insertion, rebuilding, dirty shutdown detection
and resynchronization, bad sector recovery, faulty disks tracking,
hot-spare disks. For Intel and Promise formats there is support multiple
volumes per disk set.

Look graid(8) manual page for additional details.
