14 May 1998 The first alpha version of vinum is now available for download at ftp://ftp.lemis.com/pub/vinum/vinum-0.01.tar.gz. Vinum is available under a Berkeley-style copyright. This version of vinum contains a subset of the final functionality, roughly equivalent to the ccd driver. In particular, the following restrictions apply: Automatic startup is not yet complete. It is currently necessary to re-configure the volumes every time the subsystem is started. This operation does not change the data on the disks. Detection of differences between the version of the kernel and the LKM is not yet implemented. Detaching plexes and subdisks has not yet been implemented. Reintegration of failed disks has not yet been implemented. vinum requires a special version of newfs, which has not yet been committed. The current version places some restrictions on volume names. See the documentation for further information. This version of vinum will run (hopefully) on FreeBSD 2.2.6 and recent versions of 3.0-CURRENT. It may also run on 2.2.5, but I haven't tested it. Due to changes in -CURRENT, it will not compile on versions older than about mid-March 1998. Due to licensing restrictions, this version does not contain the RAID5 functionality. If you are interested in testing this, please contact me privately. Don't use this version for performance testing. I have a lot of debug code in there, some of which is quite slow. At the moment, my main concern is stability. Documentation for this version includes man pages (vinum(4) and vinum(8)) and a user's guide, currently (for convenience) in /usr/src/sbin/vinum/doc. You can build PostScript versions of any of these by building the appropriate file (vinum4.ps, vinum8.ps or userguide.ps) in this directory. For convenience' sake, the distribution includes the PostScript file /usr/src/sbin/vinum/doc/userguide.ps. This document is intended to be formatted with troff; you can format it with nroff, but it will look funny. I don't intend to fix this. The documentations Makefile also refers to a file notes.*, which will contain technical notes when it is finished. All documents refer to the RAID5 functionality. Please ignore them for the time being. If you use this version, *PLEASE* give me some feedback, even if things work fine. In particular, of course, I'd like to hear of any problems you have either with the software or the documentation. I'll also accept requests for enhancement, but don't expect to see them in the near future: there's still a lot of code to be written.
