Hello,

I used this command:

Code:

mount -t tmpfs shmfs -o size=12g /dev/shm

and now:

Code:

[root@centos ~]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda2       457G   37G  397G   9% /
tmpfs            12G  606M   12G   5% /dev/shm
/dev/sda1       190M   38M  143M  21% /boot
shmfs            12G  606M   12G   5% /dev/shm
shmfs            12G  606M   12G   5% /dev/shm
shmfs            12G  606M   12G   5% /dev/shm

How can I remove or unmount the following:

Code:

shmfs            12G  606M   12G   5% /dev/shm
shmfs            12G  606M   12G   5% /dev/shm
shmfs            12G  606M   12G   5% /dev/shm

Umount /dev/shm thrice?

Thanks for your reply.

Code:

[root@centos ~]# umount /dev/shm
umount: /dev/shm: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))

I used:

Code:

 fuser -km /dev/shm

and again ran umount /dev/shm then its worked fine

Thanks from the bottom of my heart
