There is a new Ruby and sysadmin related book available, Practical Ruby for System Administration. The last few years Ruby has really sailed up as a good alternative to Perl and Python. Personally I must say I prefer Python over Perl but with all the hype around Ruby I […]
In their latest release Nexenta added support for ZFS boot. I also wrote an article about how to clone and boot another ZFS file system. The process is quite simple but it still contains a number of steps.
To make things even easier I decided to write a script to automate the process. This can be […]

To my delight I saw that Practice of System and Network Administration, The (2nd Edition) is available for pre-order on Amazon. I already own the 1st Edition and it is really a great book. I consider it a must read for any sysadmin or I could even go that far that I would most […]
There was many great new features included in Solaris 10, including SMF that I blogged about earlier on how to utilize it to detect problems. Another wonderful tool is the Solaris Fault Management.
