The mountpoint can be binded to a new directory. Once you are done with it, use umount before you physically remove the floppy disk from the system. # mount /dev/fd0 /mntĪfter the successful mount, you would be able to access the contents of the floppy disk. For example, a floppy disk will be mounted as shown below. The device file for floppy disk would exist under /dev directory. It is possible to list only the specific type of filesystem mounted using the option -l with -t as shown below: # mount -l -t ext2Īs seen above, /dev/sda6 is the only ext2 partition and /dev/sda5 is the only ext4 partition accordingly. View all mounted partitions of specific type Note that the files /etc/mtab and /proc/mounts contents would be similar. Here you may also pass the device name instead of directory name (to be picked up from /etc/fstab file). Mount: according to mtab, /dev/sda6 is already mounted on /mydata Mount: /dev/sda6 already mounted or /mydata busy If you execute the same again, you would get the error message as follows: # mount /mydata #/mydata was on /dev/sda6 during installation#Īs seen above, /mydata directory is not a mountpoint, but it is present in /etc/fstab. When you pass only the directory name to mount, it looks for mount point entries, if not found, then search continuous for a device in /etc/fstab and gets mounted. Mount only a specific filesystem from /etc/fstab Some filesystem are not unmounted as its busy or currently in use. The device is found by lsof(8) or fuser(1)) (In some cases useful info about processes that use The same -a option can be used with umount to unmount all the filesystems mentioned in /etc/mtab # umount -a # /backup was on /dev/sda7 during installationĮxecute mount command with -a option to mount all the /etc/fstab entries. # /mydata was on /dev/sda6 during installation If you want all the filesystems to be mounted as specified in /etc/fstab, use -a option with mount as shown below:Įxample /etc/fstab file entries: # cat /etc/fstab After booting, system administrator may unmount some of the partitions for various reasons. The filesystems listed in /etc/fstab gets mounted during booting process. Mount all the filesystem mentioned in /etc/fstab # dfįilesystem 1K-blocks Used Available Use% Mounted on You can also use df command to view all the mount points. dev/sdb on /media/myusb type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks) Gvfs-fuse-daemon on /home/bala/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=bala) None on /run/shm type tmpfs (rw,nosuid,nodev) None on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880) Tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) Udev on /dev type devtmpfs (rw,mode=0755)ĭevpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) None on /sys/kernel/security type securityfs (rw) None on /sys/kernel/debug type debugfs (rw) None on /sys/fs/fuse/connections type fusectl (rw) Sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) Proc on /proc type proc (rw,noexec,nosuid,nodev) dev/sda5 on / type ext4 (rw,errors=remount-ro) As seen below, the USB device (i.e:/dev/sdb) is mounted on /media/myusb, which is displayed as the last line in the mount command. In the example below, after mounting the USB drive on a system, the output of mount looks like the below. View All MountsĪfter you execute mount a partition or filesystem, execute the mount command without any arguments to view all the mounts. Also, make sure that the destination directory (in the above example, /mnt) exist before you execute the mount command. In the above example, the option “-o ro” indicates that the cdrom should be mounted with read-only access. For example, a CD-ROM device will be mounted as shown below. The device file for CD would exist under /dev directory. The general mount command syntax to mount a device: mount -t type device destination_dir 1. This tutorial explains everything you need to know about both mount and umount command with 15 practical examples. Once you create a partition, you should use mount command to mount the partition into a mount point (a directory), to start using the filesystem. Once you create a partition, you’ll use mkfs command to create ext2, ext3, or ext4 partition. Once you insert new hard disks into your system, you’ll typically use utilities like fdisk or parted to create partitions.
