I run JFS on everything. Even my 486 with ancient hardware, JFS has
been the most forgiving. I could never see a need to shrink a
partition. For my new box I've gone with LVM with JFS on top. Under
the LVM I have raid1 for the system stuff, pure LVM for user stuff.
I had a WD Cavier that died. I think the bearing overheated and the
speed wasn't constant as it squeeled. After I powered-off and it
cooled, the JFS was able to sort itself out and I saved the data.
If you really need to shrink an LV, just make the new smaller LV and
put the filesystem on it, copy the data over, then remove the old LV.
Similar to moving stuff from one drive to another before LVM came along.
