Most linux servers have a separate /tmp partition to prevent from filling up the root directory with temporary files. Temp partition has a fixed size but occasionally it can get overfilled, so no new information can be recorded. If this happens one can clear out /tmp periodically using some cron job, reconfigure application to store temporary files in some other directory or increase temp partition.
To increase /tmp it is necessary to create a virtual partition and mount it.
To do this on a VPS.net server with cPanel/WHM installed please follow the steps here:
To do this on a VPS.net server without cPanel let’s go through the following steps:
Stop Apache and MySQL services.
# /etc/init.d/httpd stop; /etc/init.d/mysql stop
Take a backup of /tmp
# cp -rp /tmp /tmp.bak
Create a partition of 2GB using the below command
# dd if=/dev/zero of=/usr/temp-disk bs=2M count=1024
Create the file system on it using the mke2fs command
# mke2fs -j /usr/temp-disk
Unmount the current /tmp partition
# umount /tmp
Mount the new /tmp filesystem using the below command
# mount -t ext3 -o rw,noexec,nosuid,loop /usr/temp-disk /tmp
Set the correct permission for /tmp
# chmod 1777 /tmp
To verify the partition, execute:
Restore the content of old /tmp.bkp directory
# cp -rp /tmp.bak/* /tmp
Start Apache and MySQL services.
# /etc/init.d/httpd start; /etc/init.d/mysql start
To make sure this partition is mounted automatically after every reboot, edit the /etc/fstab and replace /tmp entry line with the following one.
/usr/temp-disk /tmp ext3 rw,noexec,nosuid,loop 0 0
Here it is, the /tmp partition size has been increased. If any issues occur while doing this please do not hesitate and contact our support team.
