For example ZFS, which doesn't currently support device removal (except 
for mirror detach) or device size shrink (but does support device grow). 
  ZFS does support file system resize but file systems are "just" 
logical things within a storage pool (made up of 1 or more devices) so 
that has nothing to do with the block device size.
