Thankyou to Alan Rollow and Keith Strange for their responses.
My question was...
Hello gurus,
I would appreciate any help on the following...
>From our Sequent machines, we are used to the following method (using SVM) to add space to an existing filesystem
(UFS over LSM)
Assign extra space to the volume.
Set the volume length to the larger amount.
Run "exfs" to provide the "newfs" type structure to the extra space.
Is there an "exfs" equivalent in LSM for DU4.0b?
Or is the only way to add space to an existing volume to
A) backup data
B) recreate the volume to larger size
C) newfs the new volume
D) restore the backup?
Cheers

The answers were:
Neither AdvFS nor UFS offer any way to extend the underlying
volume and take advantage of the new space. You can use
LSM and AdvFS to create a new volume and then add it to
the domain. Otherwise you need to use the steps you
indicated.
AND
The best way is to create lsm volumes and put those volumes into an
advfs domain. This is dynamic, you can add and remove volumes even
while the domain is mounted. You can even remove volumes with
information on them, the advfs domian moves the info to another volume
then drops the volume.
You can also incease performance in certain situations by striping large
data files across multiple volumes using ADVFS stripe command.
