Is there an alternate way to defragment it than Online JFS? Will some moves do the job??

SolutionYes.
1) Back up the fs to tape or another fs.
2) Erase everything.
3) Restore it all back.
As to whether its worth it, that is a value judgment.

Re: Is it possible to defragment a FS without Online JFS?
I'll follow your suggestion for some directories I can delete and see if it gets better.
Thank you,
Eric

Re: Is it possible to defragment a FS without Online JFS?
Note if you go to a file system as temporary storage you could get fragmentation due to condition of the file system.
I'm not sure the benefit of my approach is large, but the output of your command:
fsadm -F vxfs -D /disc2
Is different after this procedure.

Re: Is it possible to defragment a FS without Online JFS?
If you are going to backup the whole filesystem; then 'newfs' it; and finally restore it, restoring from another filesystem or from a tape isn't going to make for any more or less fragmentation!
In fact, given the choice, I'd certainly use a disk filesystem. The speed with which you can load it and re-read it will far out-strip the tape handling.
