that same OS/2 JFS was backported to AIX as JFS2, I believe.

interesting, but that article is 5 years old.   I'd be surprised if most 
of the implementation 'bugs' and anomalies discussed have not since been 
addressed.

I do wish more file systems and volume managers implemented block 
checksumming, which provides end to end integrity both for data and 
metadata.  Afaik, only Sun's ZFS fully implements this approach.
