Re: /var is 85%, need to bring it to 70%, please help me.

I have to zip the log files and nullify the original file.

 

How to do this in HP-UX ?

 

What are the commands to use this in HP Unix ?

 

/var/adm/cron and /var/adm/syslog files need to be zipped and nullify the original one.

 

How to do this ?

 

Please help me with your comands.....

/var/adm/cron and /var/adm/syslog are not files, they are directories.

 

In /var/adm/cron, there are log files that can be reduced, for example:

 

cd /var/adm/cron

cp log log.old

> log

gzip log.old

 

 

Similarly, for syslog:

 

cd /var/adm/syslog

cp syslog.old syslog.log.old

> syslog.log

gzip syslog.log.old

 

However, it is really important to look for big directories first, not big files. Use this command:

 

du -kx | sort -rn | head -20

 

Then post the result. You may have directories that have thousands of small files that need to be removed, so looking for large files will miss these directories.

Are these logs there really that large?

You're looking to remove ~700 Mb.

You should clean the logs here.

 

>  823696  /var/adm/sw/save

 

You should use cleanup(1m) to get right of superseded patches.

Re: /var is 85%, need to bring it to 70%

Hi,

Can you please give me the commands to clean up this directory ?

Won't be any impact on the server if I clean up the logs in this directory /var/adm/sw/save ?

Please give me the commands,plz...so that in future if same situation occurs, it will be helpfull for me to apply same commands.

For /var/stm/logs/os/, just remove all but the latest.


>Won't be any impact on the server if I clean up the logs in this directory /var/adm/sw/save?

 

There are no logs, just backup of superseded patches.

Have you looked at the links above about cleanup(1m) and the man page?

cleanup -c 2

Remove the -p and the patch save area for these patches will be removed.

You probably also want to see how much space you save with "-p -c 2".

You can prevent swinstall to save patched files by adding the line

patch_save_files = false

to file /var/adm/sw/defaults

You do NOT want to do this.  Unless you regularly take ignite backups or have tested the patches on another machine for some time.

 

Better to use cleanup after patching.

Hi Aparna,

 

  Simply you can use below command and find out what are the files/dir using more space.(If its log file pls take backup and nullify)

 

#find /var -xdev -type f -size +1024 -exec ll {} \; | awk '{print $9, $5}' | sort -rn +1 | awk '{print $1, $2/1024/1024 "MB"}' | more

 

 

Pr@ju!
