Hello.
I have a clean-up script that deletes > 5days old files on /archive/idocs directory. This script runs twice a week, Tuesday and Friday. This creates a log file that shows the current space usage before and after the files were deleted from the directory.
On Feb 3, the script ran and generated the below log file:
Code:
Before execution ...
Filesystem 512-blocks Free %Used Iused %Iused Mounted on
ppdd:/archive.shr 1179648 10200 100% 49 3% /archive
.
.
After execution ...
Filesystem 512-blocks Free %Used Iused %Iused Mounted on
ppdd:/archive.shr 1179648 10192 100% 51 4% /archive
As you can see, when the script ended, space usage was at 100%.
The next time the script ran, on Feb 7, the log showed (before execution) that space usage was at 91% and not 100%.
Code:
Before execution ...
Filesystem 512-blocks Free %Used Iused %Iused Mounted on
ppdd:/archive.shr 1179648 112208 91% 49 1% /archive
.
.
After execution ...
Filesystem 512-blocks Free %Used Iused %Iused Mounted on
ppdd:/archive.shr 1179648 214296 82% 49 1% /archive
How come the space usage before execution was at 91% instead of 100%? I have confirmed with our AIX team that no files were manually deleted from the directory before Feb 7. Instead, another batch of arc* files were written to the directory on Feb 4, days before the script ran on Feb 7.
Thank you in advance.

Reason: illegible font
what does 5 days old mean - last accessed 5 days ago or created 5 days ago - in the second case it might be that something was still using it while your script run first time - but the process finished and released the space before you run your script again.
Hi all,
I am looking for help with a script for displaying the space available from a df - h command for / (root).
The problem is: If it is below 700 MB I have jobs that are failing... Is there a way I can do a calculation? If it above 700 MB it is good, if it is below 700 MB it will fail.... (5 Replies)
Hi everyone,
Got an interesting one (well, interesting to me)
I have a box with a 5Gb / mount point. Checking for large files I found nothing and in fact when I did a full du I found that there was only 1.6Gb in use! And yet 100% used in /
So there's an unaccounted 3.4Gb somewhere!
