use of fsadm command to increase the filesystem space

[whiteSox]

Hello ,

I just run the command lvextend -L 500 /dev/vg00/lvol_number the command was completed successfully as i do have online jfs installed on that machine .But when i issue a
fsadm -F vxfx -b 51200 /tmp i try to shrink it instead of extending it ...Thanks all for your help...

b is blocks I believe

fsadm -F vxfs -b $(( (newsize * 1024) * 1024 )) /tmp

you need to specify in MB.

fsadm -F vxfs -b 500M /tmp

Shalom,

I've never understood why fsadm was not more clear so that one could use a size that makes sense for other utilities.

This one gets a lot of early users of fsadm.

The good news: It would never really try and shrink the fs that much.

The bad news: this "feature" is more or less explained on the man page.

Hi,

The -b option specifies size in kb , so either mention the newsize in kb or better to use m or g along with the value to indicate MB or GB, thus
fsadm -F vxfs -b 500m /tmp

lvextend -L 500 /dev/vg00/lvol_number means extend to 500 MB

To extend tmp you need to:

fsadm -F vxfs -b 500M /tmp
