Docker uses file systems inspired by Unionfs, such as Aufs, to layer Docker images. As actions are done to a base image, layers are created and documented, such that each layer fully describes how to recreate an action. This strategy enables Docker's lightweight images, as only layer updates need to be propagated (compared to full VMs, for ...
A mount point is a location in the partition used as a root filesystem. Many different types of storage exist, including magnetic, magneto-optical, optical, and semiconductor (solid-state) drives. Many different types of storage exist, including magnetic, magneto-optical, optical, and semiconductor (solid-state) drives.
The mount command instructs the operating system that a file system is ready to use, and associates it with a particular point in the overall file system hierarchy (its mount point) and sets options relating to its access. Mounting makes file systems, files, directories, devices and special files available for use and available to the user.
In these two examples, a file called "Track 1.mp3" stored in the root directory of the mounted volume could be referred to as "F:\Track 1.mp3" or "C:\Music\Track 1.mp3", respectively. In order to assign a mount point for a volume as a path within another volume, the following criteria must be met: The mounted-to volume must be formatted NTFS.
To bring a volume group online, the "vgchange" tool: Searches for PVs in all available block devices. Parses the metadata header in each PV found. Computes the layouts of all visible volume groups. Loops over each logical volume in the volume group to be brought online and: Checks if the logical volume to be brought online has all its PVs visible.

Volume management treats each PV as being composed of a sequence of chunks called physical extents (PEs). Some volume managers (such as that in HP-UX and Linux) have PEs of a uniform size; others (such as that in Veritas) have variably-sized PEs that can be split and merged at will. Normally, PEs simply map one-to-one to logical extents (LEs ...
Mount points can be created in a directory on an NTFS file system, which gives a reference to the root directory of the mounted volume. Any empty directory can be converted to a mount point. The mounted volume is not limited to the NTFS filesystem but can be formatted with any file system supported by Microsoft Windows.
