Hallo miteinander,
auf der vor einigen Tagen zu Ende gegangenen AsiaBSDCon ist auch Bluffs (BSD Logging Updated Fast File System) vorgestellt worden. Auf der Seite der AsiaBSDCon wird dazu folgendes geschrieben:
"Bluffs: BSD Logging Updated Fast File System
Author:
Stephan Uphoff (Yahoo!, Inc./ups at FreeBSD.org, USA)
Abstract:
This paper introduces Bluffs, a journaling file system that is mostly compatible with the Fast File System (FFS) on disk structure. The FFS has been successfully used for a long time. However increased disk capacities have made the classic crash recovery using a file system checker (fsck) a prohibitively time expensive operation. Soft Updates [4] and background fsck were introduced to combat the problem but added code complexity to FFS. Bluffs goal is to replace FFS by providing the same functionality as FFS with better error recovery and a fresh simple code structure. Allowing bidirectional migration of file systems between FFS and Bluffs format should make transitioning easier, provides file system checker tools to Bluffs and allows booting with the standard bootstrap loaders. "
Das ist leider alles was ich zu dem Thema finden konnte. Weiss jemand mehr?
Grüße
Thomas
