The answers were very consistent and can be summarized as follows
(formulated by Paul E. Rockwell, thanx):
One word answer: No.
More complex answer:
With a UFS file system, backing up, extending the logical volume, then
reloading the volume is the only way to go. The UFS file system structures
are statically assigned at newfs time and are not touched when extending
a volume (logical or physical).
The only method of extending a file system is to start with an AdvFS file
system. If the domain fills up, you use LSM to create a new volume, and add
that volume to the domain.
Extending an AdvFS domain's file space by resizing the underlying volume is
a feature that's been requested, but no commitment has been made to when
such functionality will be available.
