Complete guide for mounting drives in RHEL/CentOS

In this tutorial, we are going to discuss how we can mount various devices on a RHEL/CentOS system using command line interface.
To view all the mounts on the system If we want to see all the devices that are currently mounted on our machine, run $ mount
To unmount a device To unmount an already mounted device, run $ umount mount_point For example, if a device is mounted at /newdrive & needs to be unmounted, run $ $ umount /newdrive
Mounting a NFS shared drive To mount a NFS shared drive on the Linux machine, run $ mount 192.168.1.100:/nfs_share /newdrive Here, 192.168.1.100 is the IP address of the machine with NFS & /nfs_share in the name of the folder that has been shared. This again is a temporary mount & we will need to create an entyr in /etc/fstab for the permanent mount $ vi /etc/fstab 192.168.1.100:/nfs_share /newdrive nfs defaults 0 0 here /newdir, is the mount point for drive that we created.
Mounting a Samba shared drive There are many ways by which you can access samba shared device on your machine but we will be using mount command. Command to mount a samba share on Linux is , $ mount –t smbfs -o username=dan,workgroup=office,password=12345 192.168.1.100:/samba_share /newdir Here, dan is username to access samba drive with a wotkgroup ‘office’ & password ‘12345’. 192.168.1.100:/samba_share is the samba device address. To permanently mount a samba drive, open /etc/fstab & create an entry, $ vi /etc/fstab //192.168.1.100:/samba_share1 /newdir smbfs rw,user,username=dan,password=12345 0 0
Mount a new HDD partition To mount a new HDD partition with ext4 filessytem on Linux, we will first create a mount point $ mkdir /newdrive & then will mount the freshly created partition onto our machine by running, $ mount /dev/sdb2 /newdrive Where, /dev/sdb2 is the newly created partition. However the mount will be a temporary mount & the partition will be un-mounted if the system reboots. To permanently a HDD partition, we need to make an entry in /etc/fstab file. $ vi /etc/fstab /dev/sdb2 /newdrive ext4 defaults 0 0
Mounting a FAT32 based USB drive or HDD Mounting a USB based drive is similar to mounting a new partition with one exception that we will also need to mention the filesystem when mounting a usb drive. Command for mounting a USB drive is $ mount –t vfat /dev/sdb1 /newdrive To permanently mount a ntfs drive on the system, open /etc/fstab file & add $ vi /etc/fstab /dev/sdb2 /newdrive vfat defaults 0 0
Mounting a NTFS based usb drive or HDD To mount a NTFS based drive, we need to install package named ‘ntfs-3g’ on our system. This package can be installed using yum by running the following command, $ yum install ntfs-3g Once install we can mount the drive, $ mount –t ntfs /dev/sdb1 /newdrive To permanently mount a ntfs drive on the system, open /etc/fstab file & add $ vi /etc/fstab /dev/sdb2 /newdrive ntfs-3g defaults 0 0
Mounting a CD/DVD To mount a CD/DVD onto the system, run $ mount -t iso9660 -o ro /dev/cdrom /mnt Here, /mnt is mount point for CD-Rom. To permanently mount a CD/DVD-rom on the system, open /etc/fstab file & add
$ vi /etc/fstab /dev/cdrom /mnt iso9660 defaults 0 0
Mounting an ISO to system To mount an ISO to Linux system, run the following command $ mount -t iso9660 -o loop rhel_X86-64_7.0.1.iso /mnt To permanently mount an ISO file on the system, open /etc/fstab file & add $ vi /etc/fstab rhel_X86-64_7.0.1.iso /mnt iso9660 defaults 0 0 (Recommended Read: Creating SWAP partition using Fdisk & Fallocate commands) That’s it guys, this was our tutorial on mounting various devices on RHEL/CentOS machines.
