Re: file system

You need bring down file system below 100% , then only it will allow to increase your file system,you need look for large file

cd /opt
du -sk *


find /opt -xdev -type f -size +5000000c -exec ll {} \; | sort -nk 5

If you have Online JFS, then you can extend the LV online,

#lvextend -L
#fsadm -F vxfs -b M /opt


Work is life, you know, and without it, there's nothing but fear and insecurity.

>VVS: you need look for large file

This won't work for /opt. All of the files there should be "read only" files for the product. If you remove one, you probably should remove the whole product tree.
(Of course there may be a chance of junk files being left there.)

If you need more space, you need to extend it or add symlinks to other filesystems.

Re: file system

Always look for the biggest directories first:

du -kx | sort -rn | head -30

If there is an HP product that you do not use and it occupies a lot of space, you can use swremove to remove the product. You may have a poorly designed application that stores temporary files in /opt. Or /opt may simply be far too small (less than 1GB in size). In that case, you'll have to extend /opt. You can use the optional Online JFS tools to extend the filesystem or without these, reboot into single user and extend the lvol followed by extending the filesystem.

Re: file system


If you are looking to decrease the disk space utilization for the '/opt' filesystem and don't want to (or can't) enlarge it, please note this:

The appropriate way to delete product trees is to first ascertain if the product was installed with the Software Distributer tools ('swinstall'). If so, there is a record in the Installed Product Database (IPD) in '/var/adm/sw' that you want to correctly reflect the presence of the product. Use 'swremove' to remove SD-installed products in '/opt'.
