Subject: How to increase the partition size of /tmp which logically points to /usr/tmpDSK?

Log in to SSH using root access and do the following commands:

/etc/init.d/chkservd stop

/etc/init.d/httpd stop

/etc/init.d/mysql stop

/etc/init.d/postgresql stop

/etc/init.d/exim stop

umount /tmp

umount /var/tmp

If you get the error βioctl: LOOP_CLR_FD: Device or resource busyβ
while doing umount, do the umount /tmp again. If it still says resource
busy, itβs time to approach your sysadmin. Or else system may stop
responding on further actions.

replace β512000β³ β2048000β³ β /scripts/securetmp

If you donβt want to edit /scripts/securetmp directly, you can use the below script.

Create a file, paste the small script below, and then run βsh file_name_you_createdβ

#!/bin/bash

echo -n "How many GB you want the /tmp to be ? "

read GB

echo "Editing /scripts/securetmp file to have tmp size to $GB GB"

replace "512000" "$((GB*1024000))" -- /scripts/securetmp

/usr/bin/chattr +i /scripts/securetmp

rm /usr/tmpDSK

/scripts/securetmp

cd /tmp

/etc/init.d/chkservd start

/etc/init.d/httpd start

/etc/init.d/mysql start

/etc/init.d/postgresql start

/etc/init.d/exim start

/etc/init.d/securetmp start

A df -h after that should show the increased size.

Just to note though, if for any reason your machine hangs, we cannot be held responsible
