NAME
[email protected], systemd-storage-block.socket, systemd-storage-block - Storage provider exposing local block devices as storage volumes
SYNOPSIS
systemd-storage-block.socket
DESCRIPTION
[email protected] is a system service that implements the io.systemd.StorageProvider Varlink[1] interface, exposing the system's block devices (such as disks, partitions, and device-mapper nodes) as storage volumes that may be acquired by other programs as file descriptors.
The service is socket-activated via systemd-storage-block.socket, which listens on the AF_UNIX socket /run/systemd/io.systemd.StorageProvider/block. The socket directory /run/systemd/io.systemd.StorageProvider/ is the well-known location where storage providers register, see storagectl(1) for an enumeration tool.
See also [email protected](8) for a complementary implementation that exposes regular files and directories from a backing file system.
VOLUMES
The volumes exposed via the provider are identified by an absolute path (which must begin with /dev/), i.e. as a kernel block device node such as /dev/sda or /dev/disk/by-id/.... Volume names that are not normalized or that do not begin with /dev/ are not accepted.
OPTIONS
The following options are understood:
- -h, --help
-
Print a short help text and exit.
- --version
-
Print a short version string and exit.
FILES
/run/systemd/io.systemd.StorageProvider/block
AF_UNIX socket the service listens on. This is the canonical location for the "block" storage provider, and is enumerated by storagectl providers.
Added in version 261.
