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.
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.
This feature is unsupported at this time, is not yet fully
functional, and may cause serious problems.
See the xfs man page in section 5 for additional information.
If unsure, say N.
