Logic Exception

First of all, you need Postgres version 8.2 or newer since mogdbsetup refuses to run with older versions. Anyways, I spent a quite a bit of time trying to install MogileFS with Postgres. I was getting "Can't create temporary test database:" errors. The answer was in the ~/.cpan/build/mogilefs-server-2.34/blib/lib/MogileFS/Test.pm file. The temp_store subroutine was defaulting to MySQL... Here is the setup step by step on my Fedora 12: yum install mogilefsd yum install mogstored yum install perl-CPAN // if needed yum install perl-MogileFS-Client perl-MogileFS-Utils yum install perl-DBD-Pg yum install perl-IO-AIO Setup services. chkconfig --levels 345 mogilefsd on chkconfig --levels 345 mogstored on Setup a test database to be used during compilation. $ createuser -SRlD mogile $ createdb -E UTF8 -O mogile tmp_mogiletest Setup environment variables for testing $ MOGTEST_DBUSER=mogile $ MOGTEST_DBHOST=dbhost $ MOGTEST_DBNAME=tmp_mogiletest $ MOG...

Today, while I was trying to set up Nagios on my local box at work when Nagios refused to start due to bad configuration error. Starting nagios:CONFIG ERROR! Start aborted. Check your Nagios configuration. It took some to time to realize that a "check_command" line has to be defined even for passive check. define service { use local-service service_description passive_service check_command check_dummy!2 active_checks_enabled 0 passive_checks_enabled 1 } The best explanation is from the 2.0 docs located at: http://nagios.sourceforge.net/docs/2_0/freshness.html What Happens When A Service Check Result Becomes "Stale" If the check results of a service are found to be "stale" (as described above), Nagios will force an active check of the service by executing the command specified by the check_command option in the service definition.

Ok, here goes my first blog post ever... Last Friday, I decided to upgrade from Fedora 10 to 12 using the PreUpgrade tool. The download and the installation process went well until the time came to boot into the new system. I suspected something was wrong when I realized the fc12 kernel line was missing from the Grub menu, and I was "relieved" to see I was right the whole time when I was presented with: Give root password for maintenance (or type Control-D to continue): I could not even type.
