du for total 3

[gatetec]

// AIX 5.2.8

I need to figure out the ** total size ** of an AIX node in GB for a capacity planning.
I like to know the total size by mounted filesystems vs the others.

thx much

 

[sbrews]

so why dont do a:

df -g

that will give the various sizes (total, free, etc) in GB for all all file systems.

OR

you could do:

du -sg /some/mount_point

that would give the total size in GB for the specified mount point.

Add a little color to your PUTTY terminal: faq52-6627

 

[gatetec]

du -sg under root@prod:/> gives the **total size** of the node regardless mounted or unmounted, and it includes /dev and other filesystems, dir, etc?

thx much

try doing first lsvg to get the volume groups then for each volume group do lsvg volume_group_name and see the used PPs vs total PPs

for example,

lsvg rootvg

This will get you the total based on the overall size of all volume groups, which sounds more like what you want.

lsvg | while read vg
do
lsvg $vg
done |\
perl -ne '
  $megs += $1 if /TOTAL PPs:.*\((\d+) mega/;

  END{ print $megs . " total megabytes\n";}
'

It gives a lot more than the actual total size.
How can I get the sum of acutal total size?

Good morning,

what's wrong with

cd /
du -g

?

Shouldn't that produce the required output ?

gatetec,

If by "actual total size" you mean the space used by files and directories on the filesystem, you're not going to be able to check unmounted systems. Commands like 'du' need to be able to examine the filesystem and it's mounting that makes that possible. One utility that does know how to navigate an unmounted filesystem is fsck, but I'm not sure if it'll give you the information you need.

If you mean the space allocated to logical volumes, just change "TOTAL PPs" in the script I posted to "USED PPs".
