The sources are available at http://oss.software.ibm.com/developerworks/opensource/jfs.

I've been talking to some Linux people today, but it's too early to say anything specific. They do have a volume manager, but the (Linux) people I spoke to think it's significantly inferior to Vinum. They also seem to think that the best thing about releasing JFS sources might be the ability to look at the code while writing another one which is better suited to the Linux environment. They could very well be right. Greg -- When replying to this message, please copy the original recipients.
