Can you be more specific?
My vinum.conf looks like this, if this is to be more specific:
drive ad5 device /dev/ad5s1e
drive ad6 device /dev/ad6s1e
volume raid0
plex org striped 127k
sd length 0 drive ad5
sd length 0 drive ad6

That depends on your configuration.
That is as above.

The command will be 'vinum start'.
Thank you!

Who knows?
You at least know from this mail that I don't... :-)
The real issue is the configuration of your volume (not "raid").
Sorry.

Well, then I'm in trouble.

Can you please be more specific? Is the configuration entry the one
above, vinum.conf? Perform other incantations?
If you have two or more plexes, you shouldn't need to do any of this.
As I don't have two or more plexes it seems I have to do all of it. :-)
Thank you for a reply in advance!
Best regards,
Paul
