If you have problems with Vinum, please read what it says at the end of vinum(4) in the section DEBUGGING PROBLEMS WITH VINUM. You can also read it at and http://www.lemis.com/vinum/how-to-debug.html, and you should normally check known bugs at http://www.lemis.com/vinum/bugs.html. > After several page faults and fsck's on reboot I will loose an entire > drvie.

With the information you supply, it's difficult to tell. It could be a known problem: we do have one outstanding problem with RAID-5. To quote the man page: 4. The RAID-5 functionality is new in FreeBSD 3.3. Some problems have been reported with vinum in combination with soft updates, but these are not reproducible on all systems. If you are planning to use vinum in a production environment, please test carefully. > PS; anyone thinking of playing with vinum I suggest you dont start out > with 4 18 gig drives ..:) If you make these suggestions, you should say why. I don't know of any problems. What have you had? Maybe they are related to your panics.
