a744e0d33d start plex/subdisk:
Add -i option to delay between blocks copied, to reduce performance
   impact.

   Remove -v option, things work now.

Rewrite parity maintenance functions.

Rebuildparity: Add -v option to check whether it was broken before
rebuilding each block.

cef69d78bb Implement vinum_rebuildparity, which had got forgotten. In the
process, move the body of vinum_rebuildparity and vinum_checkparity to
a new function, parityops.

85882abb00 New function checkupdates: check whether configuration updates are
enabled and print a warning message in varous places if they are not.

Fix typos in comments.

Change some indents to approach style(9).

initvol: If init fails, place the subdisks in a "down" state.

vinum_start(): If we're starting a plex, try doing it directly.  It's
possible that the state of the plex differs from that of the subdisks,
for example if somebody has used 'setupstate'.

New functions vinum_raid4 and vinum_raid5 to create RAID-4 and RAID-5
volumes, analagous to vinum_mirror and vinum_stripe.

vinum_checkparity: Don't try to check the parity of a non-parity plex,
print a rude remark instead.

ea3ea274b1 Don't use /dev/vinum/rsd/XXX for init as it doesn't exist any more.
Without this change, you cannot do the required init on a new raid5 volume.

2768093ea6 Explicitly type large scalar parameters to avoid compilation warnings
on alpha.

Submitted-by:	Bernd Walter <ticso@cicely.de>

Add function vinum_mv, which moves subdisks to different drives.  This
function just does the low-level configuration changes; the resultant
subdisk is stale if it previously had any contents, otherwise it is
empty (i.e. in need of initializing if it's RAID-5).  We still need to
handle getting the contents moved over, but the current version will
suffice to migrate subdisks from a disk which has failed.

vinum_start:  Get the revive block size right.

23528a021d Change the name of the v flag variable from 'verbose' to 'vflag',
indicating the multiple use (verbose or verify).

initsd: rewrite:
  Initialization is now done in the kernel.

  Verify (again!) if -v is specified.

  Allow specification of a blocksize, the length to be transferred in
  one transfer.

vinum_revive:
  Allow specification of a blocksize, the length to be transferred in
  one transfer.

fad2b6452b vinum_init: Fix message typo.
vinum_start: bzero the statinfo.dinfo struct.  The lack of this was
causing sporadic failures of the start command.

b095b120af Tidy up some indentation and comments.
vinum_init(): Change name of variable plexindex to objindex, which
	      better describes its purpose.

initsd(): Add a second parameter to determine whether it should wait
	  for completion or not.  This allows it to DTRT when called
	  with the -w flag either directly or via initplex().

Add 'setstate' command (function vinum_setstate ()) to implement the
VINUM_SETSTATE_FORCE ioctl for diddling individual object states.
This is a repair tool which can also be used for panicing the system.
Use with utmost care if at all.

Add unimplemented commands 'checkparity' and 'rebuildparity'.  Watch
this space.

d9170b4e00 vinum_init:
wait correctly for completion.
   set object in initializing state before initializing.
   Don't set the plex up, it should go up automatically.

vinum_start:
  If any objects are not up on start, list them.

vinum_attach:
  Make sure we always have the object information before examining it.

vinum_replace:
  Start writing.

create_drive, vinum_concat, vinum_stripe, vinum_mirror:

ec2e2a6723 Remove the volume, plex, sd and drive commands which allowed the user
to bypass the create command.

vinum_stop:
  Allow -f option.

Add commands for simplified configuration:
  concat - create a volume with one concatenated plex
  stripe - create a volume with one striped plex
  mirror - create a volume with two concatenated or striped plexes

7a4bec173b vinum_create: pass 'force' flag to ioctl VINUM_STARTCONFIG.
Semantics:

  When creating a new drive, if the drive already has a vinum label,
  and name doesn't match the specified drive, do it anyway if the
  'force' flag is specified.
