AIX

Hi,
I am new to AIX 5.3.I want to work with it and when I check the space of AIX machine..its /usr is 99% full.So I am not able to add anything in that.
filesystem is as below--

So can anyone tell me how can I resize it and increase the size of it.

2nd thing,when I am trying to reinstall OS but during installation,it is not asking for partitions.

Please help me to resolve it.

Thanks in Advance....

I assume this is a new system, because you are talking about reinstall


often, when /usr is full, the cause was a previously made Technology Level update, or another software installation, with the option "commit software updates" set to no and "save replaced files" set to yes (in the smitty install menu)

so if it's a new system, you can drop the old files, using smitty install > software maintenance and ... > commit applied software updates

in normal cases you do the update, wait a few weeks, and if everything works properly you commit the new and drop the old filesets


other possibility ist, that /usr ist simply too small, then you should check the "mount" command and see if filesystem is jfs2 (default in aix 5.3)
this would work with jfs(1) filesystem too, but you can't reduce its size while operating, which is a big advantage of jfs2

then try the command

Code:

chfs -a size=+300M /usr

or

Code:

chfs -a size=+1G /usr

for example

if you get an error please post it here

I downloaded the Base Java6.sdk from IBM web-site and when I am doing untar it.I am getting only executable file.but according to the documents,
This package is required:
So I try to find these docs but not able to get it there.So can u please help me out in this case..

I would like to say a word or two about the /usr filesystem in AIX systems in general:

in most systems haveing the /usr filesystem filled to capacity is risky if not even desastrous. Not so in AIX systems. AIX software packages are usually installed in installp format (aka ".bff-files") and installp, AIX' package manager, can increase the filesystem size automatically to accomodate exactly what is being installed. Have a look at the man page of the "installp" or the "geninstall" command for details.

Because of this it is usually a waste of space to increase "/usr", because when this space would really be needed it will be assigned automatically anyways. The only exception is when software not properly packaged is installed. I suggest repackaging it first before installing in production environments as much as this is possible (ideally, if the software installation is only copying files/directories somewhere the the repackaging is done in a few minutes).

Aside from installing software /usr is very rarely written to and its content is usually static, so you don't need to reserve space for eventualities.

I hope this helps.
