Right. I realize that now after having tried to no avail to get vinum to forget about previous attempts that failed or crashed this box. It essentially went like this. Try to create a RAID5 volume. Panic. Okay so take a couple of steps back and create a RAID1 volume. That worked. Okay now try to get vinum to forget about that configuration and do a RAID10 configuration now. No dice. It refused to forget about the previous RAID1 configuration. I did all of the above in a number different orders and nothing worked. Not even redoing the RAID1 configuration that had worked before. > Well, I'd start off by reading the section DEBUGGING PROBLEMS WITH > VINUM in vinum(4), or http://www.vinumvm.org/vinum/how-to-debug.html, > or both. Basically, I have almost no information to go on. What was > the panic? Thanks for the reply Greg. I finally figured out how to make it work. Basically I newfs'd the partitions, ran 'vinum create', and then changed the type to vinum. This was the only way I could get vinum to not try to "add on" to my previous failed attempts. It seems to work great so I'm going to leave well enough alone until I get another box with a similar setup that I can play with. Is there a better way than 'vinum resetconfig' to get vinum to forget everything you've told it about volumes, plexes, disks, ... than resorting to what I did? The nature of the description in the manpage that I read at least a dozen times in the last couple of days lead me to believe this would do what I wanted, but try as I might it didn't do what I expected nor what I interpreted the manpage said it did. One thing that I failed to mention in the previous post was that despite having run 'vinum resetconfig', 'vinum dumpconfig' still returned information that looked like it was from previous attempts. Not setting the partition/slice type to vinum until after I ran 'vinum create' seems to have worked around this.
