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

[Martin Knoblauch <Martin.Knoblauch@TeraPort.de>]

Hi,

 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?

 Is this scaling only for size, or also for performance (many disks on
many controllers) like XFS (at least on SGI iron)?

Thanks
Martin
