Adam, Can I please ask you to sit down and write a paper for USENIX on this whole issue and how you resolved it? You and Stan have done a great job here documenting and discussing the problems, troubleshooting methods and eventual solution(s) to the problem. It would be wonderful to have some diagrams to go with all this discussion, showing the original network setup, iSCSI disk setup, etc. Then how to updated and changed thing to find bottlenecks. The interesting thing is the complete slowdown when using LVM snapshots, which points to major possibilities for performance improvements there. But those improvements will be hard to do without being able to run on real hardware, which is expensive for people to have at home. I've been following this discussion from day one and really enjoying it and I've learned quite a bit about iSCSI, networking and some of the RAID issues. I too run Debian stable on my home NFS/VM/mail/mysql server and I've been getting frustrated by how far back it is, even with backports. I got burned in the past by testing, which is why I stay on stable, but now I'm feeling like I'm getting burned on stable too. *grin* It's a balancing act for sure!
