- When inode clusters are emptied of inodes, keep them around
- on the disk (ikeep) - this is the traditional XFS behaviour
- and is still the default for now. Using the noikeep option,
- inode clusters are returned to the free space pool.
+ When ikeep is specified, XFS does not delete empty inode clusters
+ and keeps them around on disk. ikeep is the traditional XFS
+ behaviour. When noikeep is specified, empty inode clusters
+ are returned to the free space pool. The default is noikeep for
+ non-DMAPI mounts, while ikeep is the default when DMAPI is in use.
