I'm not sure what gets destroyed.  It's been a while since I played with 
OS/2, but when I moved from OS/2 to Linux, the only thing I remember 
getting messed up was that OS/2's boot manager lost the labels it used 
in the boot menu.  The partitions themselves were fine.

Linux JFS should be able to mount the OS/2 JFS volumes if the JFS volume 
consists of a single partition (no linked partitions) and the volume is 
formatted using the default 4K block size.  I haven't verified that the 
Linux JFS won't do something that OS/2 finds incompatible, so I'd 
recommend mounting the OS/2 partitions read-only from linux if you can.

EVMS will allow any OS/2 volumes to be recognized, but I don't think the 
OS/2-compatibility work is complete yet.  There is no target date yet 
for supporting JFS block sizes other than 4K.

Of course, you should be able to access HPFS from linux too, subject to 
being on a single-partition volume.
