Hi,
I'm having some issues setting up gvinum on a new system. My ultimate
goals are to:
a) leave some free space on the disk for me to grow into (either
with new filesystems or using growfs) as needed, and
b) mirror essential filesystems (/, /usr, etc) onto a second disk
But at this point I can't even get the gvinum configuration to survive a re=
boot.
Here's my info:

However, following a reboot, my gvinum config looks like:

The subdisks seem to be getting detached from the plexes, which are
getting detached from the volumes. The "attach" command doesn't seem
to be supported in 6.0's vinum implementation, so at this point I need
to recreate the plexes & subdisks.
Any thoughts? Am I missing something?
Thanks.
