Can i resize logical volume

[Musaddaq_1]

Hi
We have HP-UX platform on 9iRac(Raw device).
We have seperate Logical Volumes for each Datafiles. My question is Can i resize my Logical volume once it gets filled or i have to make larger LV and copy datafile there.
Plz advice me some better solution regarding this

Hi,

You can resize (grew) your filesystem. You will have to stop your application before you extend you filesystem.

# lvextend -L size_in_mb /dev/vgXX/lvolx

Just don't use extendfs because you are using raw volumes.

Best regards,

Hi,
I think you will have to recreate the LV (since this is an raw device) with the new size and therefore you need to have backup of previous Datafile. Wait for some more inputs as well.
