The Vinum Volume Manager

The Vinum Volume Manager is a block device driver which implements virtual disk drives. It isolates disk hardware from the block device interface and maps data in ways which result in an increase in flexibility, performance and reliability compared to the traditional slice view of disk storage. Vinum implements the RAID-0, RAID-1 and RAID-5 models, both individually and in combination. Vinum is part of the base distribution of the FreeBSD operating system. Versions exist for NetBSD and OpenBSD. This site contains the following information about Vinum: Known bugs in Vinum What to do with Problems in Vinum How to Replace a Failed Drive Performance Issues Increased Resilience Availability Some Examples The Big Picture Brief introduction to Vinum Full Introduction Startup Object Naming Issues Three Problems Driver Structure Vinum feature wish list Implementation Current Implementations Future Directions FreeBSD and NetBSD source trees. This site contains the RCS versions of the “super-source” which includes code for both hidden behind #ifdefs. It uses some very flaky code in a Makefile to trim it to the code in the individual trees. This would be the best code to use to start a new port. If anybody wants to tidy up the Makefile for stripping the #ifdefs, please do so. I also have some notes on the structure of the driver. Don't count on these being up to date, but they might help. Documentation Vinum is documented in the man pages vinum(4) (the driver) and vinum(8) (the control program). These man pages are being continually updated, so the version you have will probably not be as up-to-date as the ones below. Beware, however: these man pages refer to the development version of Vinum in the -CURRENT version of FreeBSD, which may not correspond to the version you are running. In particular, FreeBSD 4.0 removes block devices, which has changed some aspects of the way Vinum works.

I kept thinking that if I can only do "this" or "that" then I will get a hold of this situation and resolve my debt problem. However I found that things just seemed to get worse than better. I figured that 'one day' I would somehow get a hold of some windfall of cash that will then take care of this. It did not take me long to realize that this was a fantasy and that I needed some help pretty soon or I would be in danger of losing many of my possessions or even worse end up in bankruptcy. But where was I to turn? I then came across a website that offers debt consolidation through a trusted company that has been around for many years and has great reviews from its clients. I was a little hesitant to begin with but they really do offer a no obligation free consultation. They told me how they can help and how to get me out of this mess. Now my only regret was I wish I would have gotten on this one a little earlier.      Another way I found some ways to save money was through getting a better dental insurance plan. This site offers you various dental plans with dentists right in your own area. You can end up saving an average of 30%. When you have a family with some young children, this savings can really help relieve the pocket book when it comes time to going to the Dentist.      Have you even moved to an area before and really wanted to get involved in a gym but did not know where to turn? Or perhaps you have been living in an area for quit sometime and have never even gone to a gym before. If this is the case, I recommend you check out the nation wide Health Club Directory. Its database has thousands of health clubs within the United States. Its worth just checking them out.
