An update on the Sun Blade 150
October 15, 2007Well, I finally got around to finishing doing all the installs and setup on the Blade 150 I had laying around. In the end, since it only had 1gb of RAM and only 1 600 Mhz UltraSPARC II processor, I decided to go with FreeBSD instead of Solaris. Initially, Solaris worked great serving up a […]

Sun rebrands itself as Java…
August 27, 2007…at least, that’s what Jonathan makes it sound like in his post here. Looks like Sun is going to be changing its stock symbol from SUNW to JAVA in an effort to appeal to people who don’t know what “SUN” is about, but have heard about “Java” in all their daily use. While I agree […]

First suggestion for Project Indiana
June 14, 2007Okay, so almost everyone has heard about Project Indiana right? The one where SUN tries to make Solaris like Linux so they can compete in more areas and get all the wonderful features of Solaris on more platforms. Well, I have a suggestion for you: Don’t use Java for your installer. Yea, sure, it’s fine […]

Submission: local/remote zfs snapshot script
June 6, 2007Here’s a nifty little submission from Ralf Ramge. It will do a ZFS snapshot backup to a local directory, a remote machine and also clone and promote the filesystem on the remote machine. It keeps the last 7 backups around. Take a look: #!/bin/bash # backup_zfssnap.sh, (c) 2007 ralf [dot] ramge [at] webde [dot] de […]

Ian Murdock at OpenSolaris users group
June 5, 2007So I read quite a few Solaris blogs and when this popped up this morning I decide to take a look (warning, the movie that the post links to is >500 megs) I had expected to hear a pretty good discussion around the “linuxification” of Solaris and how Ian Murdock plans to approach it, turns […]

Not-as-simple perl script for ZFS snapshot auditing
June 5, 2007Hi everyone, I’m back again with another perl script to hopefully be useful to a few of you. Firstly, the script: http://lee.hinmanphoto.com/files/zdiff.txt (formatting long scripts in wordpress’ crazy editor is a very long and arduous process, thus I’m just linking to the script in this case, if anyone knows of a better place to stick […]

Super-simple perl script for zfs snapshots
June 1, 2007Here’s a simple script for creating daily zfs snapshots that get rotated every week (so you always have one for Mon, Tues, Wed, etc) #!/usr/bin/perl use warnings; use strict; my $zfsname = shift || die “Need a filesystem name\n”; my $day = `date`; $day =~ s/(Sun|Mon|Tue|Wed|Thu|Fri|Sat)[\S\s]+/$1/gi; my $snapname = “$zfsname\@$day”; my $exist = system(“zfs list […]

Use SVM to make RAID0 and RAID1 meta-partitions
May 17, 2007Firstly, the easy one: RAID0: Given 4 slices, each ~5g: First, need a metadb, I created a 100MB slice on c1t1d0s0 (which I am NOT using for the RAID, entirely separate drive) and ran this command to initiate the database. It is a good idea to mirror the database in a minimum of 3 positions, […]
