How to resize tmp

[yamaharr1]

I have read and read and read so many posts but the posts are very out dated and many of the commands I see in them do not work. An example is if I use the command "lsof /tmp | grep deleted" to see why my tmp is getting filled up it is not recognized.

Can anyone give an up to date list of commands and instructions on how to resizing the tmp partition?

I am using a Linux system and need to go from 485M to 1G

Here is a script to dynamically resize /tmp.

Looks interesting is there any information on how to use it? Or where to place the script?

You must be root to run this script. You can place this script inside /root.

You might do better to use cPanels securetmp script. Searching the forums for securetmp brings back several posts, including this one with chirpy's details on how to remove and recreate tmp.

If you followed that after editing /scripts/securetmp with the size you want tmp to be you should be gold.

I have had to use one of these guides already to repair tmpDSK but I didn't think about editing the /scripts/securetmp to create a larger area but would that really work?

 

[Infopro]

You bet. There are threads around here about that as well. Try the search tool, it works well.

 

[yamaharr1]

As I mentioned in my first post I have "read and read and read" I guess I should have said I have search and read, search and read, search and read but there just comes a time when enough is enough and you must post hoping for others to point you in the right direction.

Now off to the search functions again to see if I can find some guides on using the / scripts/securetmp to also resize not my ideal way of doing things but hopefully it will be acceptable.

 

[Infopro]

You should be fine.

Thanks infopro for the links, I found much of those already in other posts which promted me to write this thread because many of the commands that are used did not work for me many times I received "command not found".


But your last link was perfect and has now worked out just as I needed thanks again.

Here is a script to dynamically resize /tmp.

Can we modify the script to resize the /var partition?

Can we modify the script to resize the /var partition?

Increase the size in the /scripts/securetmp directory and then copy paste the commands below, have just done it on 5 servers worked good.

service mysql stop
service httpd stop
umount /var/tmp
umount /tmp
rm -rf /usr/tmpDSK
/scripts/securetmp --auto
service mysql start
service httpd start
df -h

cannot resize /tmp -- WHY?

I edited /scripts/securetmp:
my $tmpdsksize = 15360000; # Must be larger than 250000

Then
[email protected] [~]# /usr/sbin/lsof /tmp

Then went through steps described in post. Got this response:
umount: /tmp: device is busy
umount: /tmp: device is busy
Proceeded:
[email protected] [~]# /scripts/securetmp --auto
Securing /tmp & /var/tmp
/tmp is already secure
Setting up /var/tmp... Done
Checking fstab for entries ...Done
Logrotate TMPDIR already configured
Process Complete

BUT no change in size?
[email protected] [~]# df -h
Filesystem Size Used Avail Use% Mounted on
/usr/tmpDSK 485M 460M 0 100% /tmp

service mysql stop

yes that weird thing happened to me too , after server reboot its back to default 2gb

 

[ModServ]

Do that step by step:

pico /scripts/securetmp
Modify "my $tmpdsksize"

service mysql stop
service httpd stop
pstree -p | grep tailwatchd
then kill the processes
umount /var/tmp
fuser -cu /tmp
then kill all processes appears to you
umount /tmp
rm -rf /usr/tmpDSK
/scripts/securetmp --auto
service mysql start
service httpd start

reboot -n

Done
