CONFIG_XFS_RT: XFS Realtime subvolume support

General informations

The Linux kernel configuration item CONFIG_XFS_RT has multiple definitions:

XFS Realtime subvolume support found in fs/xfs/Kconfig

The configuration item CONFIG_XFS_RT:

• prompt: XFS Realtime subvolume support
• type: bool
• depends on: CONFIG_XFS_FS
• defined in fs/xfs/Kconfig
• found in Linux kernels: 2.6.18–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.17, 6.18-rc+HEAD

If you say Y here you will be able to mount and use XFS filesystems which contain a realtime subvolume. The realtime subvolume is a separate area of disk space where only file data is stored. It was originally designed to provide deterministic data rates suitable for media streaming applications, but is also useful as a generic mechanism for ensuring data and metadata/log I/Os are completely separated. Regular file I/Os are isolated to a separate device from all other requests, and this can be done quite transparently to applications via the inherit-realtime directory inode flag.

See the xfs man page in section 5 for additional information.

This option is mandatory to support zoned block devices. For these devices, the realtime subvolume must be backed by a zoned block device and a regular block device used as the main device (for metadata). If the zoned block device is a host-managed SMR hard-disk containing conventional zones at the beginning of its address space, XFS will use the disk conventional zones as the main device and the remaining sequential write required zones as the backing storage for the realtime subvolume.

If unsure, say N.

XFS Realtime support (EXPERIMENTAL) found in fs/xfs/Kconfig

The configuration item CONFIG_XFS_RT:

• prompt: XFS Realtime support (EXPERIMENTAL)
• type: bool
• depends on: CONFIG_XFS_FS && CONFIG_EXPERIMENTAL
• defined in fs/xfs/Kconfig
• found in Linux kernels: 2.6.14–2.6.17

If you say Y here you will be able to mount and use XFS filesystems which contain a realtime subvolume. The realtime subvolume is a separate area of disk space where only file data is stored. The realtime subvolume is designed to provide very deterministic data rates suitable for media streaming applications.

See the xfs man page in section 5 for a bit more information.

This feature is unsupported at this time, is not yet fully functional, and may cause serious problems.

If unsure, say N.
