Docker manages swarms using the Raft consensus algorithm. According to Raft, for an update to be performed, the majority of Swarm nodes need to agree on the update. [40] [41] Docker Volume facilitates the independent persistence of data, allowing data to remain even after the container is deleted or re-created. [42]
In Windows NT and OS/2, the operating system uses the aforementioned algorithm to automatically assign letters to floppy disk drives, optical disc drives, the boot disk, and other recognized volumes that are not otherwise created by an administrator within the operating system. Volumes that are created within the operating system are manually ...
OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers (LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones (Solaris Containers), virtual private servers (), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), and jails ...
Since Windows NT 3.1 (the first version of Windows NT), [4] Microsoft has defined the terms as follows: The system partition (or system volume) [5] is a primary partition that contains the boot loader, a piece of software responsible for booting the operating system. [6]: 1087 This partition holds the boot sector and is marked active. [7]: 970
Also, an OS can recognize a partition without recognizing any volume associated with it, as when the OS cannot interpret the filesystem stored there. This situation occurs, for example, when Windows NT-based OSes encounter disks with non- Microsoft OS partitions, such as the ext4 filesystem commonly used with Linux .
VTOC (Volume Table Of Contents) - Data structure on IBM mainframe direct-access storage devices (DASD) such as disk drives that provides a way of locating the data sets that reside on the DASD volume. XFS – Used on SGI IRIX and Linux systems; zFS – z/OS File System; not to be confused with other file systems named zFS or ZFS.
The Open Container Initiative (OCI) is a Linux Foundation project, started in June 2015 by Docker, CoreOS, and the maintainers of appc (short for "App Container") to design open standards for operating system-level virtualization ().
Both System and Application WPARs can be moved from one machine to another. To continue having access to the same files before/after mobility; the filesystems of a mobile WPAR must either be stored in a disk or NFS mounted (both of which should be shared and accessible from all the machines where WPAR is being moved to). The feature can be ...
