How to use RAM (physical) as disk
Introduction –
Sometime to gain performance, physical ram can be used as disk space which is very fast compare to normal hard disk.
So, how I can use RAM is disk ? go through this steps.
Step 1) Create directory as shown below where you want to mount RAM as disk
root@arunbagul:~# mkdir -p /tmp/ram
root@arunbagul:~# ls /tmp/ram
root@arunbagul:~#
Step 2) mount RAM ie tmpfs at mount point “/tmp/ram” directory-
root@arunbagul:~# mount -t tmpfs -o size=10M tmpfs /tmp/ram/
* check mounted on not ?
root@arunbagul:~# df -h
Filesystem Size Used Avail Use% Mounted on
tmpfs 10M 0 10M 0% /tmp/ram
** to mount this permanently add entry in /etc/fstab as shown below.
root@arunbagul:~# cat /etc/fstab
…
….
tmpfs /tmp/ram tmpfs defaults,size=10m 0 0
root@arunbagul:~#
– To mount this use mount command (this will mount all mount points mentioned in fstab)
root@arunbagul:~# mount -a
