Some questions, just out of curiosity: >* Fast recovery after a system crash or power outage > >* Journaling for file system integrity > >* Journaling of meta-data only > does this mean JSF/Linux always journals only the meta-data, or is that an option? Does it perform full data-journaling under AIX? >* Extent-based allocation > >* Excellent overall performance > >* 64 bit file system > >* Built to scale. In memory and on-disk data structures are designed to > scale beyond practical limit Is this scaling only for size, or also for performance (many disks on many controllers) like XFS (at least on SGI iron)?
