How to entend a file system using onlinejfs

HPUX 11.23
Need to extend a file system from 81gb to new size of 160gb. I have not used the online jfs but I think it is preferred to using SAM and I dont have to unmount the filesystem.
Current Stats:
lvol= gexdata01
volume group= vg01
Type=LVM
USE: VxFS
Total Mbytes=80000
Mount Dir=/h/data
Mbytes available: 206056 of 286056

What do I need to extend /h/data to 160GB

Re: How to entend a file system using onlinejfs

Make sure you have enough free space on the VG.

Then do..

lvextend -L 160M /dev/vg01/gexdata01

fsadm -b 160 /h/data

check the resultant size using,

bdf /h/data

Do as below,

lvextend -L 163840M /dev/vg01/gexdata01

fsadm -b 163840M /h/data

check it by using,

bdf /h/data

One small change in fsadm command.
fsadm -F vxfs -b 163840M /h/data

Vijaykumar was kind of close.

You need to fist extend the logical volume.

If you use '-L' you specify the size of the LV in MB. For 160GB, you can use:

lvextend -L 160000 /dev/vb01/gexdata01

To extend the file system using fsadm you can use:

fsadm -F vxfs -b 160000m /h/data

Note that fsadm can use the 'm' after the size so you can specify in MB rather than blocks.

Shalom,

After I lvextend the logical volume I do this, to avoid block calculations which I NEVER get right.

lvdisplay

There is a display of size in megabytes.

If the figure is 18254

fsadm -F vxfs -b 18254m /filesystem_name
