InterMezzo is a high availability file system featuring write back caching
and disconnected operation. It replicates file trees across multiple
systems, one of the systems plays the role of server, the others are
clients. InterMezzo recovers from network and server
failures. InterMezzo shares many ideas with Coda but is considerably
simpler and less fully featured.
You can find packages and source for beta 0.93 Linux 2.2 kernels in:
ftp://ftp.inter-mezzo.org/pub/intermezzo
Documentation is available on the InterMezzo WWW site:

New since the previous release:
- We have migrated to "stock" POE from CPAN
- Considerable simplification of reconnection code
- Minor improvements and feature additions to the kernel code
- RPM packages
- Minor documentation updates
- Improvements to the config tools
To reach 1.0 we have the following outstanding issues:
- Move forward to ext3 0.05c or later
- Better documentation
- Conflict detection
- Bug fixes
Particular thanks go to Shirish Phatak from Tacitus Systems
([email protected]) for very persistent debugging and testing.
Gord Matzigkeit ([email protected]) has build the RPM packages and cleaned up
the build environment for this purpose. Many others have contributed
significantly.

NOTE:
InterMezzo relies on journal file systems for recovery. This release
works with Ext3 and you must compile 0.03b into your kernel, as well as
the following 3 lines to be add in linux/kernel/ksyms.c:
#include <linux/jfs.h>
EXPORT_KSYM(journal-start);
EXPORT_KSYM(journal_stop);
