Unmounting caches

Before you delete a cache, we recommend that you unmount it from every Amazon EC2 instance that it's connected to. You can unmount a cache on your Amazon EC2 instance by running the umount command on the instance itself. You can't unmount a cache through the AWS CLI, the AWS Management Console, or through any of the AWS SDKs. To unmount a cache connected to an Amazon EC2 instance running Linux, use the umount command as follows:

umount /mnt 

We recommend that you don't specify any other umount options and avoid setting any other umount options that are different from the defaults.

You can verify that your cache has been unmounted by running the df command. This command displays the disk usage statistics for the Amazon File Caches currently mounted on your Linux-based Amazon EC2 instance. If the cache that you want to unmount isn’t listed in the df command output, this means that the cache is unmounted.

Example – Identify the mount status of an Amazon File Cache resource and unmount it
