help
- Multipath-IO is the ability of certain devices to address the same
- physical disk over multiple 'IO paths'. The code ensures that such
- paths can be defined and handled at runtime, and ensures that a
- transparent failover to the backup path(s) happens if a IO errors
- arrives on the primary path.
+ MD_MULTIPATH provides a simple multi-path personality for use
+ the MD framework. It is not under active development. New
+ projects should consider using DM_MULTIPATH which has more
+ features and more testing.
If unsure, say N.
