What can I delete from /opt

[Nial Gunn]

Hi, I need to delete some data from /opt, as it is full and I need some space. I have attached a txt doc showing the contents of /opt can anyone advise me on what to delete?

[Raj D.]

Hi Nial ,

You can not delete any files from opt as the system packages resides there.
Though you can check for any user files if occupying there :

# cd /opt
# ls -lR | sort +4 -5nr | more

And you may remove any unwanted package , with swremove to get some free space.

Cheers,
Raj.

It depends on what you do not need - If you do not need graphics, for example, you swremove them - but you need to know if this will affect any apps. The /opt directory is very hard to reduce.

Personally I would either extend /opt, or if that is not possible, I would create a new mount point in a different VG for /opt/OV and move all that data over.

There are several other directories that are non-system directories you could make their own mount points as well

[Alessandro Pilati]

In the case of /opt, search also for unnecessary .tar and .gz files:

find . -name *.gz|xargs du -k|sort -rn +0
find . -name *.tar|xargs du -k|sort -rn +0

but unless you remove software, it's quite difficult to free space in /opt, it's not /var...
Another solution is to "transfer" Ignite in another Filesystem and then make a link in /opt that refers to the new location.

So if the hints of RAJ and these are not enough, I can address you to enlarge the filesystem...

If you have OnlineJFS, you can do it at system running.
Otherwise, enter in single user mode:

Shutdown the system,
get into single user mode (hpux -is /stand/vmunix).
Then do:
mount /usr
mount /var
mount /tmp
lvextend -L new_size_in_mb /dev/vg00/lvol_of_opt
extendfs /dev/vg00/rlvol_of_opt
init 3


Hope this helps

Regards,
Alex

Essentially the answer is nothing unless you use swremove to remove some inessential packages. You could probably remove the older versions of Java. One approach would be to copy everything in /opt to another filesystem. /opt does not have to be in vg00 so it could be moved to another VG. To doi that, you would create a new, larger LVOL and filesystem and use cpio to copy everything to /newopt. You then umount /newopt and edit /etc/fstab to change /opt's mountpoint. Reboot and you are good to go. You can then free the space used by the original /opt and delete that LVOL.

Swremove, or better yet, just extend the size of it.

I seem to remember a facility to remove unused filesets/software, possibly in SAM??? I can't seem to find it on any of my 11i boxes. I wonder if it was an 11.0 feature. Anybody remember such a thing? Or is it my feeble memory playing tricks on me again?

@Pete,

I don't know such feature, but perhaps you have the "cleanup" in mind for removing old copies of replaced patches.

Thanks, Torsten, but my feeble memory recalls the cleanup command. This was something different. Maybe it was 10.20 . . . . .

The cleanup command (which is available in 11.x although 11.0 requires a patch to get the command) will not free space in /opt but rather in /var.

Hi Pete:

I believe the command you are remembering was 'freedisk'. Rather dangerous and deprecated. You can read more in the 10x manpages.
