[CentOS] Is ext4 safe for a production server?

[Brent L. Bates]

     XFS is the most stable file system I've seen or used.  I've seen it
survive power failures and disk problems with out a problem.  It is the ONLY
file system I trust.  It is stable, reliable, dependable, and practically
bullet proof.  I've been using XFS almost since it came into existence on
SGI's (IRIX) and we've been using it under Linux for years too, also with out
problems.
