Hello

I have attached a guide which should cover most things for you including extending the lvol with and without online jfs

lvextend -L /dev/vg01/lvol1 /dev/dsk/c1t1d0

then extendfs to actually extend the filesystem.

The lvextend can be done without umounting the affected filesystem. The extendfs will require a umount. The fsadm will extend the filesystem without a umount if you have OnlineJFS.

Hi Chandu,

Since you are new to HP-UX Administration, I suggest you read the following manual

http://docs.hp.com/hpux/onlinedocs/5187-2216/5187-2216.html

Look at "Managind Disks and Files" to get an idea about LVM and then try the instructions given there.

Example, increase filesystem /app on /dev/vg01/lvol1 to 2GB

lvextend -L 2048 /dev/vg01/lvol1

fsadm -b 2048M /app


That's with online JFS - else you need to umount it first, then extendfs instead of fsadm.

If u want to extend online JFS

#lvextend -L 4096 /dev/vg04/lvol1 /dev/dsk/c5t10d0
#fsadm -b 4096 /u3

If u are extending otherthan OL JFS

#unmount /dev/vg04/lvol1
#lvextend -L 4096 /dev/vg04/lvol1 /dev/dsk/c5t10d0

#extendfs -F /dev/vg04/rlvol1
#mount /dev/vg04/lvol1 /u3
