Guessing is guesswork. I need to look at the problem first, and so far we don't have much evidence for anything. On older versions of Vinum I didn't support this kind of naming, but it's been there since 3.3. There were some problems in 3.3-RELEASE, but they've been fixed, and are documented in http://www.lemis.com/vinum/known-bugs.html. > I was having frequent crashes and reboots on my vinum raid5 system, > which was had it's drives configured as > > drive vinum0 device /dev/da0s1h > drive vinum1 device /dev/da1s1h > drive vinum2 device /dev/da2s1h > drive vinum3 device /dev/da3s1h > > The system lunched the drives recently, so I can't show what > disklabel used to read, but in each case, the h partition was a > vinum partition Tht's the important part. > and each drive had at least one other partition for a minimum FBSD > install, That doesn't matter. > which is how I bootstrapped FBSD onto vinum (the box now has a 5th > HD for the OS and I don't currently have vinum running). If the disk label is wrong, you won't get the system to work at all. It should just refuse, not panic, but it won't work. > Is da#s#h a valid device for vinum, Yes.

No, that's wrong. > Also, don't know if it makes a difference or not, but I also had > swap on a raid5 plex.. I've seen somebody do that on NetBSD (with RAIDframe) recently. I don't understand why you'd want to do that. RAID-5 is very slow on writes, and swap is usually small enough that the additional hardware cost of RAID-1 would be negligible. > in fact, everything but root (and the old partitions which generally > weren't used, but were mounted rw) was on a raid5 plex.

If you have any more problems, take a look at http://www.lemis.com/vinum/how-to-debug.html and give me the information I ask for there.
