IceFS
IceFS is a research filesystem that groups files into cubes to localize filesystem faults, recovery and journal transactions.
The OSDI 2014 prototype modifies Ext3/JBD in Linux 3.5. Cubes separate metadata allocation, bypass failed ancestor directories through indirection, and split transactions. Virtual journals still use shared journal space. [1]
Mount-time failures can remain global. Independent commit threads can increase device flush overhead; this is filesystem containment, not device redundancy or universal performance isolation. [1]
