I've always avoided XFS because A) it wsan't supported natively in RHEL 
anyways, and B) I've heard far too many stories about catastrophic loss 
problems and day long FSCK sessions after power failures [1] or what 
have you

is B) no longer an issue?

I wanna know how come JFS/JFS2 (originally from IBM) isn't more popular 
in the linux world?  At least as implemented in AIX, its rock stable, 
journaling, excellent performance, and handles both huge files and lots 
of tiny files without blinking.   jfs2 handles really huge file systems, 
too.  I really like how, in AIX, the VM and FS tools are coordinated, so 
expanding and reorganizing file systems is trivial, nearly as simple as 
Sun's ZFS.


[1] replace power failure with unexpected ups event if you prefer.
