reducing filesystem size

[Joe Robinson_2]

Hello,

When trying to reduce a fs using the command:

fsadm -F vxfs -b 800m /fsname

I get the following error:

vxfs fsadm: /fsname is not the root inode of a vsfx file system

if someone can lead me in the right direction, I'll divy up the points!

Extra credit: I'm using 11.00 w/ Online JFS. using the above credit and then lvreduce, I should be able to do this without unmounting the filesystem, correct?

Thanks in advance,
Joe
