    SubjectRe: 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)?
