Make room!

Frederic Wartner — Thu, 06 Mar 2003 18:39:56 GMT

Hi all,
I'm beginning to use a 715/50 under 10.20, and I need to free some disk space.
What can I delete? Is there a way to delete all the log files and other unessential stuff?
Thanks!

Any particular file system that you're interested in purging?

You can delete most everything under /tmp and /var/tmp. You can use SAM to trim log files.
You can use find to remove core files or check for excessively large files.

A little more info on what you're after would help focus the answers you're going to get.

Depend on what you need. In a normal scene, these things can be done:
1) Clean all un necessary files from /tmp. This file system holds temp. files only.
2) Clean /var/adm/wtmp and btmp files. These were log in informations, can be cleared if not needed.
3) Remove files from /var/adm/crash. These has last system crash information.
4) /var log files. Find all log files and can be removed/trimmed.
5) run command - cleanp - to clean old patches from system. Read man pages before use.
6) Check root file system and remove all un necessary files from it.
7) The OS file systems are normally under vg00. Others can be removed if you don't need any old data.
8) CAUTION - when removing files from /, /etc, /usr, /sbin, /var, /opt, /stand etc.
9) Use SAM's routine tasks to trim files.

Here's what I go after

1) cores
find / -type f -name core -exec rm {} \;

2) Logs
find / -type f -name "*log" -exec ll {} \;

3) try the cleanup command
/usr/sbin/cleanup
Please read the man page before running it.

4) Check for old software that you may not need. Start with /opt. Perhaps you have old tools left on the system that can be removed.

Good luck,
Tom

Hi:

Since you note "old", download and install PHCO_20824 for 10.20 from the ITRC Patch database. This is the 'cleanup' patch utility which you may or may not have.

No reboot is required to install. This will trim log files in '/var/adm/sw' and remove superceded patches. If you have never run this, you may gain substantial space in '/var'. This is the *only* recommended way to maintain '/var/adm/sw'. Simply do:

# cleanup

Regards!

Thanks to all for helping.
Does anybody know how to type {} on a 46021B HP keyboard?

You can also run swremove to remove products that are not used. NOTE: Take care with this! Make sure the products are really not needed. (Do a system backup first.)

The swremove utility will also check for dependencies and remove them when appropriate.

I would use swremove before running cleanup. Cleanup may prevent the removal of products and patches (especially patches).

Hey Frederick!
Two things:
1. Although I can't help you with your particular keyboard I have a similar problem and here's my workaround. I've created a text file on another workstation called "braces" which has only the two characters { and }. I've FTP'd this file to the workstation that doesn't have the braces. Whenever I need to type the braces I can cut and paste them from the "braces" file.
2. Some other types of files you may want to look for to free up disk space are .tar files and backups that may have been created by another sysadmin (.bak, .orig, etc).
Have a grand day, Bob

Hi,

Is your problematic keyboard a French one, as your 715 might be configured for a US keyboard?

regards,

Darren.

Re: Make room!

Frederic Wartner — Fri, 07 Mar 2003 11:28:56 GMT

Yes, it's a french keyboard. How do I "tell" it to the system? Something like "keyb fr" in DOS?
Anyway if it doesn't work I'll use the text file solution.
Thanks again for your help.

Darren Prior — Fri, 07 Mar 2003 11:36:07 GMT

Hi,

Have a look at the file /etc/kbdlang; I'm guessing it contains something like blah_blah_US.

DON'T attempt to edit the file! Just move it to another location and reboot the box; you should then be offered a menu where you can choose the actual keyboard type you have.

regards,

Darren.

Another place I've recovered disk space from is by removing foreign language sets. I'm not going to use the Japanese, Bulgarian....
It did create a problem once. I removed German and our SAP application would not start. We're in the U.S. and I figured we only needed English. Apparently some things under the covers use German.

Re: Make room!

Frederic Wartner — Sat, 08 Mar 2003 16:10:16 GMT

Seems a good idea to remove useless language files.
Where can I find these files?

Re: Make room!

S.K. Chan — Sat, 08 Mar 2003 17:42:18 GMT

There are in /usr/lib/nls BUT I would not mess with those files as they are not big in size, furthermore you would not know what might break. All that have been mentioned earlier are the ones you need to pay attention to. Another area of opportunity if you're really deperate is the man pages and software documentaion (eg: glance, SAM, etc). For instance /usr/share/man which I bet would make up about 20MB. Online doc like /opt/perf/paperdocs is about 30MB (if you got glanceplus installed). Again .. only if you're really desparate for space and make sure you have ways of recovering those files back if you need them.

commit the old patches will save some space after JRF's patch is installed.

cleanup -c 1

Will get rid of anything superseded more than once, but remove a possible backout path.
