AFAIK AIX JFS != Linux JFS. It's more like OS/2 JFS and IBM ported it to linux to enable their os/2 customers to move to linux.

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

Also whenever fs reliability discussion pops up I like to point people to this paper: http://www.cs.wisc.edu/wind/Publications/iron-sosp05.pdf

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.
