userland tool:
Use the vfs.devfs.generation sysctl to test for devfs presense
(thanks phk!) when devfs is active it will not try to create the
device nodes in /dev and therefore will not complain about the
failure to do so.
Revert the change in the #define for VINUM_DIR in the kernel
header so that vinum can find its device nodes.
Replace perror() with vinum_perror() to print file/line when
DEVBUG is defined (not defined by default).
kernel:
Don't use the #define names for the "superdev" creation since
they will be prepended by "/dev/" (based on VINUM_DIR), instead
use string constants.
Create both debug and non-debug "superdev" nodes in the devfs.

directly off the drives.
This command shows a minor problem: it requires that the device nodes
exist, whereas kernel Vinum does not. Thus dumpconfig may show no
configuration for certain drives which are up and happily running.
This is documented in the man page.
Describe -i option for start.
Update description of start command (will now work on plexes).
Update discussion of choice of stripe size (don't use power of 2).
Remove references to raw devices.
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.
Describe stop -f to stop when config updates are disabled.
Explain in more detail why Vinum needs its own partition type, and why
you can't make it the c partition.

Change checks for striped or RAID-5 plexes to a macro 'isstriped',

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

vinum_lsi: If the subdisk is initializing or reviving, don't wait a

ms up to 1 second. This makes for a barely perceptible delay.

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.

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.
