00f32ecbd0 Add to GEOM RAID class module, supporting the DDF metadata format, as
defined by the SNIA Common RAID Disk Data Format Specification v2.0.

Supports multiple volumes per array and multiple partitions per disk.
Supports standard big-endian and Adaptec's little-endian byte ordering.
Supports all single-layer RAID levels. Dual-layer RAID levels except
RAID10 are not supported now because of GEOM RAID design limitations.

Some work is still to be done, but the present code already manages basic
interoperation with RAID BIOS of the Adaptec 1430SA SATA RAID controller.

63297dfd4a Some improvements to GEOM MULTIPATH:
- Implement "configure" command to allow switching operation mode of
running device on-fly without destroying and recreation.
 - Implement Active/Read mode as hybrid of Active/Active and Active/Passive.
In this mode all paths not marked FAIL may handle reads same time,
but unlike Active/Active only one path handles write requests at any
point in time. It allows to closer follow original write request order
if above layers need it for data consistency (not waiting for requisite
write completion before sending dependent write).
 - Hide duplicate messages about device status change.
 - Remove periodic thread wake up with 10Hz rate.

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.

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.

e7926a3703 Reimplemented "gpart destroy -F". Now it does all work in kernel.
This was needed for recover implementation.

Implement the recover command for GPT. Now GPT will marked as
corrupt when any of three types of corruption will be detected:
1. Damaged primary GPT header or table
2. Damaged secondary GPT header or table
3. Secondary header is not located in the last LBA
Marked GPT becomes read-only. Any changes with corrupt table
are prohibited. Only "destroy" and "recover" commands are allowed.

5ad4a7c74a Bring in geli suspend/resume functionality (finally).
Before this change if you wanted to suspend your laptop and be sure that your
encryption keys are safe, you had to stop all processes that use file system
stored on encrypted device, unmount the file system and detach geli provider.

This isn't very handy. If you are a lucky user of a laptop where suspend/resume
actually works with FreeBSD (I'm not!) you most likely want to suspend your
laptop, because you don't want to start everything over again when you turn
your laptop back on.

And this is where geli suspend/resume steps in. When you execute:

	# geli suspend -a

geli will wait for all in-flight I/O requests, suspend new I/O requests, remove
all geli sensitive data from the kernel memory (like encryption keys) and will
wait for either 'geli resume' or 'geli detach'.

Now with no keys in memory you can suspend your laptop without stopping any
processes or unmounting any file systems.

When you resume your laptop you have to resume geli devices using 'geli resume'
command. You need to provide your passphrase, etc. again so the keys can be
restored and suspended I/O requests released.

Of course you need to remember that 'geli suspend' won't clear file system
cache and other places where data from your geli-encrypted file system might be
present. But to get rid of those stopping processes and unmounting file system
won't help either - you have to turn your laptop off. Be warned.

Also note, that suspending geli device which contains file system with geli
utility (or anything used by 'geli resume') is not very good idea, as you won't
be able to resume it - when you execute geli(8), the kernel will try to read it
and this read I/O request will be suspended.

Refuse to attach providers where the metadata provider size is

of the wrong size without the new -f switch.  The new -f switch
forces the metadata restoration despite the provider size, and

2b4969ff9e Change how multipath labels are created and managed. This makes it easier
to support various storage boxes which really aren't active-active.

We only write the label on the *first* provider. For all other providers
we just "add" the disk. This also allows for an "add" verb.

A usage implication is that you should specificy the currently active
storage path as the first provider.

Note that this does not add RDAC-like functionality, but better allows for
autovolumefailover configurations (additional checkins elsewhere will support
this).

So small block size doesn't benefits linear I/O operations in FAST and
significantly slowdowns in ECONOMIC (default) mode. For single stream random
I/Os so small block doesn't give much benefits, as access time is usually
bigger then transfer time there. Same time it requires all heads to seek

"split" is very ineffective for devices with rotating media as HDDs.
To be effective, it needs that transfer time reduction due to block

of 2MB and above, which is almost not applicable in real life.

dc344ca5a4 Allow humanized numbers for LBAs, as well as partition indices for
gpart(8). LBAs in particular are ugly. The ganularity is a sector,
but users expect byte granularity when specifying the size or offset
with a SI unit. Handle LBAs specially to deal with this.

0dd9f21c23 Prefer the start and end attributes over the offset and size
attributes. The start and end more accurately describe the
space taken by a partition. The offset and size are used to
describe the effective (usable) storage of that partition.

a468c003ef - When writing metadata to a geom provider, open the it as read-write since it
might do subsequent reads from other providers. This stopped geli (and
  probably other classes using g_metadata_store as well) from being put on top
  of gvinum raid5 volumes.

Note:
The reason it fails in the gvinum raid5 case is that gvinum will read back the
old parity stripe before calculating the new parity stripe to be written out
again.  The write will then fail because the underlying disk to be read is
opened write only.

So, rather than printing the error:

7f792cd758 Use humanize_number(), rather than a home-grown algorithm for
formatting a number in a human-friendly way.

Note that with this commit a megabyte changed from 1000000 to
1048576 and a 80G disk is now printed as being 75G in size.
This is deliberate. It's consistent with the core of geom(8).
However, the original choice for a megabyte being 1000000 was
on purpose and matches what disk vendors put on the box. The
consistency is considered more important.

ba196edbd2 By default backup geli metadata to a file. It is quite critical 512 bytes,
once it is lost, all data is gone.

Option '-B none' can by used to prevent backup. Option '-B path' can be
used to backup metadata to a different file than the default, which is
/var/backups/<prov>.eli.

The 'geli init' command also prints backup file location and gives short
procedure how to restore metadata.

The 'geli setkey' command now warns that even after passphrase change or keys
update there could be version of the master key encrypted with old
keys/passphrase in the backup file.

Add regression tests to verify that new functionality works as expected.

Update other regression tests so they don't create backup files.
