Hi Eric,

If you do not have online JFS then you cannot extend the filesystem online. You need to reboot into single user mode to extend it, since you cannot unmount /opt in multiuser mode.

Yes you can install online JFS and after that you can do FS management online. Once you have installed online JFS run the below commands to extend /opt online.

#lvextend -L
#fsadm -F vxfs -b M

Examble:
# lvextend â L 10000 /dev/vg00/lvol4
# fsadm â F vxfs â b 10000M /opt

Hi Eric,

Ignore the Junk characters in the example.

examble: To extend to 10GB of total size

#lvextend -L 10000 /dev/vg00/lvol4
#fsadm -F vxfs -b 10000M /opt

Hi Eric,

You need bring down file system below 100% example:- 99%, Than Only It will allow to Increase you file system,

Step1 :- We need look for large file

cd /opt
du -sk *

or

find /opt -xdev -type f -size +5000000c -exec ll {} \; | sort -nk 5

How to extend File system with out JFS Installed,

Hence you /opt part vg00 ,

You need bring Server into Single User mode and extend file system,

steps:-

shutdown -ry 0
interupt ISL> hpux -is
# mount -a

Sum up the recent size of the file system and the additional size.

Extend the logical volume.

# lvextend -L

# lvextend -L 10000 /dev/vg00/lvol2
# extendfs -F vxfs /dev/vg00/rlvol2


If you have ONline JFS no need downtime you can do ONLINE Extention as below

lvextend -L
fsadm -F vxfs -b 10000M /opt

Thanks,
Johnson

I don't think you need to bring system down to single user mode when without online JFS. The only thing need to be done is to umount /opt, although it is safe to have an ignite backup for /opt. The procedure is:
# vgextend vg00 /dev/dsk/c*t*d* (in case you don't have enough vg)
# lvextend -L 4000 /dev/vg00/opt /dev/dsk/c*t*d*
# umount /opt
# extendfs -F vxfs /dev/vg00/opt
# mount /opt
# bdf /opt

Hi

Online JFS is a Priced that is a Licensed product of HP and you need to order for that.

The install is quite Straight Forward that is swinstall and add the codeword and install.

After that you can online Extend/reduce Fileystems (Reduction has got limitations),Online Defreag, Snapshot, change and set Extent Attributes etc
