Hi.

Using sam to increase logical volume will automatically extend the file
system too. However, this is slow. Alternatively, we can do the same
with command based. But, with command based, we need to umount and
mount the filesystems even though we have online JFS.

Anyone with the same experience?

I assume you try to use the command "extendfs". But you should try "fsadm -F vxFs ...".

See man fsadm_vxfs

With Online JFS you simply need to extend the Logical Volume first:
lvextend -L (size in MB) /dev/vgxx/lvolx
Then extend the filesystem:
fsadm -F vxfs -b (lvol MB size * 1024) /filesystem_name

In the below example I want to extend /depot (mounted on lvol2 in vg01)
from 1Gb to 2Gb:
# lvextend -F 2000 /dev/vg01/lvol2
# fsadm -F vxfs -b 2048000 /depot

If the filesystem is not vxfs then it cannot be increased using Online JFS.

Yup...

with fsadm, the filesystem do not need to be umounted. However, for
extendfs, it has to be umounted.

Any idea why this is so?

Extendfs is HPUX standard.
OnlineJFS is a additional product, which you have to purchase, it
enables the online features.
