Actually, in regard to alan_at_nabeth remarks below. Here is what I do
and
works great.
(1) Filesystems are within AdvFS domains.
(2) Add new disk, create LSM volumes using whole disk or
subdisks as desired.
(3) Add new LSM volumes to existing AdvFS domain and presto
all filesystems in that AdvFS domain now have that amount
of additional space free.
With AdvFS, the filesystems can automatically use (growby)
the amount of new space added to the AdvFS domain. Since,
it is easy to add new space to domains on-line, this is
my preferred method of handling the issue.
AdvFS addvol and rmvol commands are beautiful things.

Many thanks for the speedy responses (just wish they bore better
news
;-) --
O r i g i n a l q u e r y:
Now that I have issued the command "volassist growby u01
1000000", and
rebooted, and can see from "voldg free" that my free space went
down
by that amount, and "volprint -ht" shows a corresponding
increase of
/u01 : how come my "df" still does not show an increase of
1,000,000
blocks? It would seem that I would need to re-create the
filesystem
-- is there a safe way to do that in-place, or do I need to back
up,
newfs, restore?
BTW: this is a UFS under LSM
R e s p o n s e s f o l l o w :
======================================================================
You're on the right track. The filesystem was created with size
'n'.
Even though the underlying volume has grown, that won't change
the
size of the filesystem. You'll have to back up the filesystem,
remove
it, newfs it, and restore.

Neither UFS nor AdvFS automatically grow the file system to fill
newly
available space. As it turns out there still aren't utilities
that
can grow the file system offline or online to use newly
available
space. I've heard rumors of plans for such a utility for AdvFS,
but
it has been a consisently less desirable feature than such
things as
MP friendlyness and not panicing the system in the face of an
I/O
error. I think OSF provides such a utility for UFS in their
distribution, but we didn't include in Digital UNIX.
The only solution is to backup, re-create the file system and
restore.
Please make your dissatisfaction known to the CSC, so they can
make
it known to the engineering groups.
