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.

f9c32ccded Don't print any error message if we can't open the history file. This
replaces an older attempt to silence vinum(8) when started in
single-user mode.

Add entries for vinum_raid[45].

VINUM_CDEV_MAJOR.

4b62b353ed vinum_ldi: Honour the 'recurse' flag and show the subdisks on this
drive if it is set.

vinum_lvi: Change line spacing.  This is still not right.

Change checks for striped or RAID-5 plexes to a macro 'isstriped',
which now also includes RAID-4.

Change checks for RAID-5 plexes to a macro 'isparity', which now also
includes RAID-4.

vinum_lsi: If the subdisk is initializing or reviving, don't wait a
whole second to check whether it's advancing; wait in increments of 50
ms up to 1 second.  This makes for a barely perceptible delay.

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.

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.

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.

Update information about partition type for Vinum drives.  They
*should* be of type 'vinum', but currently we still accept (and
complain about) partitions of type 'unused'.  At a later date, only
'vinum' will be accepted.

the debug superdevice when we're compiled without debug, or the normal
superdevice when we're compiled with debug.  If this succeeds, print
an informative comment and exit.

the wrong module can cause confusion, including loading both versions
(which conflict with each other) and incorrect ioctls, which cause
unintelligible error messages.
