Check for /dev/shm mounted as temporary file system failed

Fix:-

[root@rac2 ~]# mount -o remount,size=2G /dev/shm
[root@rac2 ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3              26G   12G   13G  50% /
/dev/sda1              99M   46M   49M  49% /boot
tmpfs                 2.0G     0  2.0G   0% /dev/shm

The size of in-memory file system mounted at /dev/shm is "2048" megabytes which does not match the size in /etc/fstab as "0" megabytes

Error:-

Check for /dev/shm mounted as temporary file system passed

Open /etc/fstab using vi or any text editor :-

Locate the line of /dev/shm and use the tmpfs size option to specify your expected size,

tmpfs      /dev/shm      tmpfs   defaults,size=2g   0   0


The /etc/fstab content format is documented in man fstab and the tmpfs filesystem options can be found in man mount

change effective immediately, run this remount command :

mount -o remount /dev/shm
