Is it to find the process that is using so much of space and to kill it ?
To identify the userid dumping data to fill up /usr ?
To create an alarm for a defined threshold level ?
I am looking only to reduce /usr to normal precentage such as expand the file or trnsfer to another file.
In most other UNIX dialects this might be a problem, but in AIX (you are in the AIX forum, so i suppose you use it, not any other UNIX dialect) it is not. The reason is, that practically all the files in /usr are put there by installation tools and the AIX installation tool (installp) will expand the filesystem itself if it runs out of space during an installation.
Most AIX systems are far into the nineties if i issue a "df -k /usr" and it never has posed a problem in the years i have been working with AIX.
thank you bakunin to your feed back about "installp", but I need now to reduce the percentage for /usr could you help for this, because i didn't install S/W .
I still do not understand why you do have to increase the available space (IMHO this is a waste of diskspace), but here is how you do it:
1. find out, how much space is left in the rootvg and decide, how much you want to assign to the /usr filesystem:
I have marked bold the relevant parts: In this example your smallest assignment unit is 128MB (PP size) and you have 910 (free PPs) of these 128MB-chunks available. As your rootvg is mirrored (see the LP to PP ratio of 1:2) you will need 2 PPs for every new LP you assign. Right now you have 20 LPs (=> 20x128MB=2.5GB) assigned. For the sake of the example i assume you want to increase it by 1GB, which would be 8 LPs.
2.) Increase the size of the logical volume:
3.) Increase the size of the filesystem:
Filesystems are measured in (512-bytes-)blocks. Calculate how many blocks you have to increase, then increase the filesystem (use ^D to leave bc):
Dear Friends,
I would like to increase the size of a file system from 10GB to 15GB.
System is runing on HP-UX 11.31.
Please help in the matter.

Hi,
I'd like to know how can I figure out my disk space area on AIX machine, for example to the situation of ( df -g ) which I have in my system :
the area used by (/opt/oracle) file system is (98%) now.
the free area on (/opt/oracle) is (0.75) now.
the total size in Gigabyte... (1 Reply)
When I do df -h, I see that one of my partitions is out of space.
Then when I do du -h, I get thousands of files. How do I only look at files over a specific size. I want directories over 500m to be returned only. (2 Replies)
Hi,
We currently have an Oracle database running and it is creating lots of processes in the /proc directory that are 1000M in size. The size of the /proc directory is now reading 26T. How can this be if the root file system is only 13GB?

I have the next code, and the output is incosistent, what is the problem:
free blocks: 1201595
block size: 4096
total size(free blocks * block size): 626765824
1201595 * 4096 not is 626765824, what's the problem???

How to find the free size currently FileSystem has, on the disk mounted?
I know 'df' lists all the mounted disks, but I am interested to know details
for the filesystem, in which currently I am working. (7 Replies)
