Re: Announcing Journaled File System (JFS) release 1.0.0 available

 first of all congratulations for finishing the initial first release.
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)?
