There it is, Raid 0. "Drive numbers (minor devices) of eight and larger are treated specially. Drive 8+x is the x+1 way interleaving of devices rk0 to rkx. Thus blocks on rk10 are distributed alternately among rk0, rk1, and rk2." Goes on to enumerate precautions, like don't use the same physical drive for both normal and interleaved operation. I myself never tried this, because I didn't have enough confidence in the error-free operation of a single RK05 drive, let alone two or more. Note that this feature disappeared by the time of 7th Edition RK(4). carl -- carl lowenstein marine physical lab u.c. san diego clowenstein at ucsd.edu _______________________________________________ TUHS mailing list TUHS at minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs From tfb at tfeb.org Thu Jul 2 18:53:08 2009 From: tfb at tfeb.org (Tim Bradshaw) Date: Thu, 2 Jul 2009 09:53:08 +0100 Subject: [TUHS] 6th Edition RAID In-Reply-To: <5904d5730907011210h5ebf8061y381e267fd313aad3@mail.gmail.com> References: <5904d5730907011210h5ebf8061y381e267fd313aad3@mail.gmail.com> Message-ID: <43CBC33E-982F-4C4E-806E-B9D98462B18D@tfeb.org> On 1 Jul 2009, at 20:10, Carl Lowenstein wrote: > I thought I remembered something interesting about 6th Edition RK05 > handlers, and went back to check RK(IV) in the manual.

Right now I have seeded the site with a few pages, but as with all wikis, we need a whole bunch of people to upload content. So if you have any anecdotes, or electronic documents, or any other Unix-related information, then please join the wiki and add it in! To join the wiki, click on the 'log in' link on the top-right, and then click 'request account', which will prep the account and wait for me to authorize it. At the moment, I have created a small set of page categories, listed below. If you can think of any other categories, feel free to edit http://www.tuhs.org/wiki/Wiki_Categories Cheers & thanks in advance for participating! Warren Pages on the Unix Heritage Society Wiki should belong to one of the following categories. If you can think of others, please edit this page. All pages should provide links and citations to allow the reader to verify the content. Anecdote: A story about Unix history or using Unix. Page should include the name of the person telling the anecdote, and details of the time period covering the anecdote. Artifact: a file (tarball, disk/tape image) or a system stored in the Unix Archive. The page should provide a web link to the artifact on minnie, and details of the artifact's provenance: how it came to be in the archive, who submitted it, where did the artifact come from etc. Book: a monograph (but not a paper or document, see below). Page must include citation details for the document, and if possible an image of the book cover. Summaries and reviews of a book are welcome. Document: a written document (but not a paper, see below). Page must include citation details for the document, and if possible a link to the document on-line. Entity: an organisation (e.g. AT&T, BTL, USL), or a group (e.g. CSRG). Page should provide details of the entity and their relationship to the history of Unix. Image: a visual image. Page should provide an explanation of the image and its relationship to the history of Unix, plus a link to the image on-line. Paper: a paper which appeared in a journal or conference. Page must include citation details for the paper, and if possible a link to the paper on-line. Person: an individual. Page should provide details of the person and their relationship to the history of Unix. Tip: a tip or suggestion for installing, configuring or using an old version of Unix. Version: a specific version of release of Unix. Page should detail the features of the version, its geneaology, date of release etc. If there is an artifact of this version in the Unix Archive, then the page should provide a link to the artifact's wiki page. _______________________________________________ TUHS mailing list TUHS at minnie.tuhs.org https://minnie.tuhs.org/mailman/listinfo/tuhs From jcapp at anteil.com Mon Jul 6 03:28:54 2009 From: jcapp at anteil.com (Jim Capp) Date: Sun, 05 Jul 2009 13:28:54 -0400 Subject: [TUHS] www.tuhs.org now a MediaWiki In-Reply-To: <20090705092501.GA12569@minnie.tuhs.org> References: <200906050348.n553mr9N017809@cuzuco.com> <46b366130906051140m35e27e17i4f124fb74be3d0f7@mail.gmail.com> <20090605233040.GA35610@minnie.tuhs.org> <20090605233943.GA10056@mercury.ccil.org> <20090705092501.GA12569@minnie.tuhs.org> Message-ID: <4A50E2D6.2040309@anteil.com> Warren, I'm excited about www.tuhs.org as a MediaWiki. In my spare time, I have been working on graphics and other anecdotes in celebration of UNIX turning 40. Some time ago I answered a post on TUHS regarding my idea of a site as a birthday tribute. I have reserved a number of domains and am working on just that. Much of the materials I have collected would also work very well on TUHS Wiki. I applied for access earlier today. Let me know where you need help. Also, as I mentioned in an earlier post, we developed and maintain the UNIX books list on groklaw's site. See groklib.anteil.com.
