InterMezzo is an obsolete distributed file system written for Linux, distributed under the GPL. The kernel component is not included in the current 2.6 kernel. It was included in the standard Linux kernel from kernel version 2.4.15 but was dropped from the 2.6 kernel. InterMezzo is designed to work on top of an existing journaling file system such as ext3, JFS, ReiserFS and XFS. Typical applications of replication mode are: * A cluster of servers operating on a shared file system. * Computers that are not always connected to the network, such as laptops.
