The temporal directory (/tmp ) in Red Hat based systems is not a real partition (LVM partition) [1]. The file system is tmpfs instead of LVM in order to prevent DoS attack [2]. But you might want to increase the size file-system if the default value is not enough. For instance, if you have Desktop distribution and you are using common dev tools such as Eclipse, Netbeans, and so on, the default size is probably not enough.
The solution is very straightforward. We edit the file /etc/fstab and we directly increase the size as follows:
The solution is very straightforward. We edit the file /etc/fstab and we directly increase the size as follows:
none /tmp tmpfs size=8G 0 0
Then we need to re-mount the filesystem again.
# As root
$ mount -a
We check if we /tmp directory was finally resized:
$ df -h
