Configuring a File System to Automatically Mount (Linux Instances)? ›

On Linux instances, if you want to automatically mount exported file systems during an instance boot, you need to add the mount information in the /etc/fstab file. Log into the instance where you want the file system mounted. See Connecting to an Instance. Create a mount point, if one hasn't been created.

You can mount file systems for a single session using the mount command, and permanently by editing /etc/fstab . Mounting needs to be done by an administrator, either by logging in as root or by using the sudo command. There are some cases where mounting is done automatically, like when you insert a USB flash drive.

You can use the EFS mount helper or NFS to configure an EC2 instance to automatically mount an EFS file system when the instance starts. Using the EFS mount helper: Attach an EFS file system when you create a new EC2 Linux instance using the EC2 Launch Instance Wizard.

This how-to describes how to mount your network shares via autofs. Autofs should be as performant as fstab based mounting but has the advantage that your shares are mounted on demand which also should give you more reliability in case of network interuptions.

automountd locates the file system information in a map, creates the trigger nodes, and performs the mount. Autofs allows the intercepted request to proceed. Autofs unmounts the file system after a period of inactivity.

Mounting makes file systems, files, directories, devices, and special files available for use at a particular location. It is the only way a file system is made accessible. The mount command instructs the operating system to attach a file system at a specified directory.

Can you mount a single file Linux? ›

If you want to mount a single file, so that the contents of that file are seen on the mount point, then what you want is a bind mount. You can use -o ro to make it read-only on the /usr/src/linux/. config path. For more details, look for bind mounts in the man page for mount(8).

Unmounting is the reverse process from mounting – removing the association between a directory in the directory hierarchy and the device (device's storage). I modeled my explanation after (“understanding 'mount' as a concept in the OS [duplicate],” n.d.)⁠ , which you can read as well for a second perspective.

To mount an attached EBS volume on every system reboot, add an entry for the device to the /etc/fstab file. You can use the device name, such as /dev/xvdf , in /etc/fstab , but we recommend using the device's 128-bit universally unique identifier (UUID) instead.

EFS is a Network Storage system, underlying it is a storage array (SAN) and it offers the standard protocol for multi session network file systems (NFS) It's built on high speed SSD drives and is intended for shared storage for your ec2 instances, think file servers.
