I'm a sysadmin for Sentry Data Systems. I do linux and clustering and networking, and enjoy instigating a good STONITH deathmatch when I get bored.

Work-wise, I'm a giant fan of the k.I.s.s. principle - keep I.T. simple, stupid. Don't make things any more complex than the features you need.

In my spare time, I renovate houses and ride herd on a pack of dogs with extreme mental issues. My background and career are both in systems. I look at systems, analyze them, and use them or make them better. I likeCFO DIY home stuff because the systems are simple and it's rewarding to figure em out and use them. How do I know the things I do? I have probably been there, broken that, ruined the other thing, and had to figure out how to fix all of them. we have this saying in my group of friends-who-renovate-houses: "Ask me how I know."

comment Distributed Storage Filesystem - Which one/Is there a ready to use product?
Since I'm still getting upvotes on this answer, I should add that we're now using GlusterFS in production as a replacement for nfs. However, we do NOT store VM disk images, database storage files (sqlite or myisam or whatever), or other files that are prone to change frequently on glusterfs as it causes replication lash. Those we store locally on VM hosts in LVM and use DRBD to distribute to failover sites, or use built-in replication.
