NAME

md — memory disk driver

SYNOPSIS

pseudo-device md [count]

DESCRIPTION

The md driver enables use of system or user memory as a disk. Memory for the disk must be allocated within the kernel or with mdconfig(8) before the md device may be used as a disk. Its behaviour is configured by the kernel options MEMORY_DISK_HOOKS, MEMORY_DISK_IS_ROOT, MEMORY_DISK_ROOT_SIZE, MEMORY_DISK_DYNAMIC, and MEMORY_DISK_SERVER.
