List, Please let's not go into that direction. Using the filesystem for generic storage is one thing. Building a failsafe clustered system is quite another. As it stands now, the options for setting up a high availability high performance clustered filesystem are extremely limited, but the options for a high availability high performance database platform are numerous.
MySQL NDB, Hadoop HBase and Cassandra come into mind as open-source projects. There are hardly any clustered filesystem solutions that are also opensource. Yes, there's Hadoop HDFS, but it's not a generic mountable filesystem. A lot of work needs to be done before HDFS can be utilized in OpenSim. Some others exist, but most of them are propierty. On a side note: I have been using MySQL NDB storage for OpenSim in the last year without any issues. My cluster consists of a load balancer acting as management console, two mysql nodes and four data nodes. The performance difference with a standalone MySQL servier is astounding! Seriously, storing assets on disk (eg a filesystem) is a very bad idea as scalability will be an issue! Rory Slegtenhorst rory dot slegtenhorst at gmail dot com
