I am expecting /var/adm/messages size is increasing and hence /var size is increasing. Its my assume. But I don't know how to delete lot of records from the file /var/adm/messages

Please guys advise me asap. I am danger situation and i am afraid.

How are the messages.0, messages.1 etc files created, are they being created automatically? Or do those dates match reboots. You can archive and delete the old message.* files.
There are various "log rolling" solutions available.

i don't know how messages.0, messages.1 , .2, .3 has created. System is up at least for last one and half months. So, those dates should not be match with reboots. If you see messages.0,1,2,3 size has not changed. Only "messages" size has changed. I m not sure Is only for file 'messages'- the size of /var is increasing?? Or else something hidden.
Could u pls tell me about something 'log rolling'??

Bug

Hi
The first thread in this Forum is named as following:

Filesystem full - what to look for << Very useful!!!!

Please first read this thread and then you can say what is the reason that the /var file system is so full.

In my opinion the messages files are not the reason!!
(But to use the "log rolling" is very comfortable.)
The article shows you how to handle this situation.

This is my favorite command to find problematic files and directory's
du -akd /var | sort -nr | more

Best regards joerg

is see somthing like below. left value i thing telling the size. But what do i think to c these???
...
21104 /var/sadm/pkg/VRTSvxvm/save/116697-03/undo.Z
16042 /var/mail
16000 /var/mail/bgw

Hi,
for more human readable:

But you must use a ksh!
and
"M " is not a space after the "M" it is a control-I (It is a big I like Imagine (Tab is the same))

du -akdh /var | sort -nr | grep "M "

With this you can find the biggest files and the dir with the most among of filesystem place.
This search only Megabyte big files if you looking for a Gigabyte file you have to change M to G.

Best regards
joerg
