http://mkp.net/blog/index.rss Martin's musings about life, music and everything en Wed, 13 Aug 2008 19:40:00 EDT http://mkp.net/blog/index.rss/2008/08/13#20080813 <p> In my two test JBOD arrays I have a whole whack of different drives. <tt>udev</tt> gives us the possibility to access disks by UUID, id, path or filesystem label. Most people use the latter. However, my test drives generally don't have filesystems on them. And certainly not filesystems with a lifetime long enough to warrant labeling. </p> <p> Accessing via UUID, id or path is annoying because the names are really long. So I decided to create a set of udev rules enabling me to refer to drives based upon persistent nick names. </p> <p> This way I can run <code>fdisk /dev/fred</code> instead of <code>fdisk /dev/disk/by-id/scsi-SHITACHI_HUS153030VLF400_J8V1WDXA_E4TFL4M1NGDE4TH</code>. Somewhat more convenient. At least to the humans among us. </p> <p> <a href="/code/udev/">Gimme!</a> </p> Mon, 28 Jul 2008 21:37:00 EDT http://mkp.net/blog/index.rss/2008/07/28#20080728 <p> Last week was crazy! First the <a href="http://www.snia.org/">SNIA Summer Symposium</a> in San Jose where we had another face-2-face in the data integrity technical workgroup. Friday, I flew to Ottawa for the <a href="http://www.linuxsymposium.org/2008/">Linux Symposium</a>. <ul> <li> <a href="http://mkp.net/code/data-integrity/docs/ols2008-petersen.pdf">Linux Data Integrity Extensions</a> - a reprint of my paper from the Linux Symposium proceedings. </li> <li> <a href="http://mkp.net/code/data-integrity/docs/ols2008-slides.pdf">Slides</a> from my presentation. </li> </ul> </p> <p> Also, as of yesterday my data integrity infrastructure has been merged and will be in 2.6.27-rc1. </p> Sat, 14 Jun 2008 13:11:00 EDT http://mkp.net/blog/index.rss/2008/06/14#20080614 <p> <a href="http://www.perl.com/">Perl</a> is like <a href="http://en.wikipedia.org/wiki/Poutine">poutine</a>.
