    Practical ILM

    I originally posted this at http://www.318.com/TechJournal The amount of data used by Small Businesses is on target to rise 30% to 35% in 2006. Sarbanes-Oxley, HIPPA and SEC Rule 17a-4 have introduced new regulations on the length of time data must be kept and in what format. Not only must data be kept, it must be backed up and secured. These factors have the cost of data storage for the Small Business increasing exponentially. Corporations valued at more than 75 million dollars are generating 1.6 billion gigabytes of data per year. Small and medium sized companies can reap the benefits of developments being made with larger corporations. Different methods and…

    Xsan: umask and Default Permissions

    I originally posted this at http://www.318.com/TechJournal By default the global permissions for new files written into an Xsan volume are 644 (rw-r–r–). This can result in a permissions problem where one user can read another user’s posted items, but not make changes to it.  This can be resolved by changing the default umask value for groups. It’s a simple command line: sudo defaults write -g NSUmask 23 In this case, the 23 is a decimal equivalent of “rw-”. So the result of running this command line is that files posted to the shared volume will have 664 permissions (rw-rw-r–), allowing other users in the group to modify the files. Note…

    Preventing Firewall Issues with Xsan

    I originally posted this at http://www.318.com/TechJournal Introduction Xsan requires a dedicated ethernet network in the supported architecture by Apple. For systems that are obtaining directory information or need to be wired into the corporate network of many organizations this can cause issues. Namely that Xsan will attempt to use the corporate network for connectivity with clients. We see this in many configurations and it can cause dropped packets, unmountable volumes and other intermittent issues. One way to fix this for metadata controllers is to choose the network adapter that you would like to use on the metadata network in Server Admin. This can be done by: Open Xsan Admin Click…

    Regular Expression Engines

    A regular expression “engine” is a piece of software that can process regular expressions, trying to match the pattern to the given string. Usually, the engine is part of a larger application and you do not access the engine directly. Rather, the application will invoke it for you when needed, making sure the right regular expression is applied to the right file or data.
