JFS coming to OpenSolaris
The interest in beafing up the OpenSolaris storage platform is growing!
The latest addition is the JFS project. The project is looking to re-implement IBM's Journaled File System (JFS) from the available specifications. A very exciting and potentially challenging project.
Welcome to OpenSolaris and we look forward to your success!

With the availability of rapidly maturing ZFS, why would anyone waste time porting JFS?

Yes ZFS is great and getting better all the time. However data centers (and regular people) are facing a problem that they have lots of data stored in various file systems formats, and they are locked to the hardware holding those bits. So if OpenSolaris can provide a bunch of different file systems then we have the ability to move data from older file systems to ZFS.
Aside from data migration, there are some students out there who would really like to get some file system experience and porting an old file system is a great way to learn.

This is why (for one)

How proven i ZFS when used in a "high" latency/disonnected environment as a SAN ?
