Logfs is a new flash-based file system currently under development. The main author |
|||
is Jörn Engel. |
|||
There are early design documents at http://wh.fh-wedel.de/~joern/logfs.pdf. |
|||
Later additions not covered in that document include: |
|||
* Block compression, |
|||
* [[JFFS2]]-style subblock writes in the journal, |
|||
* Advanced block allocation methods to separate write-once data from write-often data. |
|||
* Block caching (useful for metadata) |
|||
* Delta storage - having an on-flash cache of recent changes without updating the wandering tree yet. |
|||
* Garbage collection algorithm - explained by the author in a [http://mirror.linux.org.au/pub/linux.conf.au/2007/video/talks/91.ogg video] at [http://mirror.linux.org.au/pub/linux.conf.au/2007/video/talks/91.pdf Linux Conference Australia in 2007] |
