I'm not sure what you mean by 'run smooth' or 'handling as easy as people 
want to make us think'... it is after all a filesystem layout rather than a 
fuel injected v12 with active suspensiou and ABS...  but I'd just say.. I 
use it and it works fine. :)

I setup the software raid with anaconda during the system install...

# tail -10 /etc/raidtab 
raiddev             /dev/md2
raid-level                  1
nr-raid-disks               2
chunk-size                  64k
persistent-superblock       1
nr-spare-disks              0
    device          /dev/sda4
    raid-disk     0
    device          /dev/sdb4
    raid-disk     1
#

... and put the lvm stuff on top of it in post install...

# pvdisplay /dev/md2

... I realise that isn't very qualitative... but there's not much to say 
about 'just works'. :)

M.

P.S.  For instances of 'works' in the above message append 'for me'.
