I would not bet on it. Read up a little more on the history of LVM/JFS
and you will understand why. The AIX stuff has been around for a while
and unix partitioning and disk access methods underlie the LVM
implementation. The WSeB implementation came next with an implementation
of LVM suitable for PC disk partitioning methods. I believe the Linux JFS
was intitially inplemented against raw partitions. I don't think the
Linux LVM is released code yet.

I'm sure they are very similar internally. I don't expect
interoperability at this point in time. If the Linux crowd is interested,
I'm sure they would eventually be able to mouse WSeB JFS drives. I doubt
IBM will put the effort into the reverse.

Calling them names doesn't change anything. Does everything you implment
work together seamlessly? I didn't think so. :-)
