Last few days I have spent installing a HA (High-availability) cluster. I needed an active\/active setup for two nodes to run Apache and PostgreSQL services. Both nodes are connected to external shared storage. It took me some time to get the concepts (especially with quorum partitions and raw devices), but afterwards, installation was a bliss ;). I have used KimberLite<\/a> clustering technology, which is open source and free. There is also a commercial solution on the site, for those who want. SourceForge.NET Clustering Foundry<\/a> was also very helpful in getting the whole thing.<\/p>\n

Meanwhile, I managed to configure my mutt to work with MS Exchange address book over LDAP. mutt-ldap-search<\/a>.<\/p>\n

I’ve also had my workstation upgraded in certain ways :) More memory, less CPU, better graphics card (GeForce 2 MX 32MB 200 Series this time). Strangely, I cannot get more then 40FPS in Quake3 using original Nvidia drivers. <\/p>\n

Now Last of all the news is that I am now testing init script for NovaNet services. Since Novastor didn’t provide with anything automatic to stop the service and remove all kinds of shared memory segments and semaphores, I had to write my own. It will be available for public, when initial testing is over ;) .<\/p>\n\n","protected":false},"excerpt":{"rendered":"\n
