Interesting XFS note

[Brett I. Holcomb]

I guess great minds think alike  - I was going to post this excerpt and get 
some comments <G>.  I haven't used XFS very long but others here who have 
feel it's very stable and robust - which is one reason I use it now.

?XFS is a filesystem with metadata journaling that is fully supported
?under Gentoo Linux's xfs-sources kernel, but is generally not
?recommended due to its tendency to lose recently-modified data if
?your system locks up or unexpectedly reboots (as a result of power
?failure, for instance)

And this after he said this is what he was doing:

Heh, say that to my mp3 pentium2 gentoo box which now registers mod_php
as pornview.... 

Pull the plug out of the box right after compilation and while it is
installing the program, libraries and files in their respective
locations and tell me what happens.

Also, do some work on a file for 3 hours without saving and then go
ahead and save while pulling the plug out of the box 1/4-1/2 second
after doing C-x C-s or pressing save and you tell me how much of the
file is there... I would be more than willing to bet the last 3-5
seconds worth of saving, work and general changes you made before an
abrupt shutdown have been L O S T.

This box is 90% XFS on LVM on RAID-0... trust me, I *enjoy* using XFS,
but have found abrupt losses of power have you lose the last 3-5 
seconds of work you were doing on the system.

I understand the extensive tests, but I'm also speaking out of my own
personal experience. Yes, a box on XFS comes RIGHT UP after a hard
shutdown, but things are and will be missing.

I think something is broken badly on his box.
