Re: degragmentation on disk or ram
Shalom Shiv,
Online JFS fsadm defragmenting provides a report that can give you an idea as to whether defragmentation was really necessary, be it after the fact.
I would suggest you see if the utility has a preview mode as many utilities do.
It's important that once its running it be left to complete its task.
Here are the guts to the script I ran in the US:
while read -r aa bb cc dd ee
do
FILESYSTEM=$bb
echo "fs is $bb $cc"
if [ "$cc" = "vxfs" ]
then
/usr/sbin/fsadm -F vxfs -D -d -E -e -s $FILESYSTEM
fi
done < /etc/fstab
# As you see it reads /etc/fstab and only touches those filesystems with vxfs on them.

Re: degragmentation on disk or ram
While one can certainly defragment a vxfs filesystem, my experience has been --- except in rare circumstances --- that it is difficult to achieve measurable, much less significant, results. Bear in mind that vxfs filesystems are extent-based and try to allocate large chunks and UNIX filesystems are geared towards creating many, many files in a short period of time.
If it ain't broke, I can fix that.
