ihashsize=value
- Sets the number of hash buckets available for hashing the
- in-memory inodes of the specified mount point. If a value
- of zero is used, the value selected by the default algorithm
- will be displayed in /proc/mounts.
+ In memory inode hashes have been removed, so this option has
+ no function as of August 2007. Option is deprecated.
ikeep/noikeep
- 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.
