SYS: Mount and unmount CIFS and NFS network file systems.

NFS network file system

To mount and unmount NFS network file systems, you need to set up a NFS server.

Install the NFS client package:

# yum install -y nfs-utils

Let’s assume that the /home/tools directory is exported by the nfsserver server.
If no working DNS, add an entry in the /etc/hosts file with the nfsserver name and its IP address.

Edit the /etc/fstab file and add the following line:

nfsserver:/home/tools /mnt nfs4 defaults 0 0

Execute the /etc/fstab file configuration:

# mount -a

To check the current configuration, type:

# mount | grep nfsserver

To unmount the NFS mounted directory, remove the previous line from the /etc/fstab file and type:

# umount /mnt

Note: If you get a message like “/mnt: device is busy”, check that you are not in the mounted directory and no process is using it. To do that, type:

# fuser /mnt

CIFS network file system

To mount and unmount CIFS network file systems, you need to set up a CIFS file server.

Install the Samba client packages:

# yum install -y cifs-utils
# yum install -y samba-client

Let’s assume that the /shared directory is exported by the smbserver server.
If no working DNS, add an entry in the /etc/hosts file with the smbserver name and its IP address.

Edit the /etc/fstab file and add the following line:

//smbserver/shared /mnt cifs rw,username=user01,password=pass 0 0

Execute the /etc/fstab file configuration:

# mount -a

To check the current configuration, type:

# mount | grep smbserver
