Become superuser or assume an equivalent role.
Create the directory that you want to mount as the TMPF file system, if necessary.
# mkdir /mount-point |
mount-point is the directory on which the TMPFS file system is mounted.
Mount the TMPFS file system.
# mount -F tmpfs [-o size=number] swap mount-point |
-o size=number |
Specifies the size limit of the TMPFS file system in Mbytes. |
mount-point |
Specifies the directory on which the TMPFS file system is mounted. |
To set up the system to automatically mount a TMPFS file system when it boots, see Example—Mounting a TMPFS File System at Boot Time.
Verify that the TMPFS file system has been created.
# mount -v |
The following example shows how to create, mount, and limit the size of the TMPFS file system, /export/reports, to 50 Mbytes.
# mkdir /export/reports # chmod 777 /export/reports # mount -F tmpfs -o size=50 swap /export/reports |
You can set up the system to automatically mount a TMPFS file system when it boots by adding an /etc/vfstab entry. The following example shows an entry in the /etc/vfstab file that mounts /export/test as a TMPFS file system when the system boots. Since the size=number option is not specified, the size of the TMPFS file system on /export/test is limited only by the available system resources.
swap - /export/test tmpfs - yes - |
For more information on the /etc/vfstab file, see Field Descriptions for the /etc/vfstab File.
