But I did pick up the latest 'all' patch as of 02-05-03.  Patched
against vanilla 2.4.20.  more hwdets@end.

I still had an older xfsdump/utils (223+225)...but they really
shouldn't do this...

I mean xfs shouldn't be soo easily crashable by a user-space program
that might send it garbage.  I know parameter checking isn't in
vogue these days and defensive programming is passe (as well as
unprofitable and considered a waste of company resources) but 
I'm iconclastic on the defensive programing thing in the kernel.
the kernel should not trust input from user space programs and should
validate parameters to see that they make sense.

It's a simple thing...just a simple level 0 dump...


OUCH!...I'd be happy to show you the script/command, but it's 
filled full of binary zeros...AGGG...corruption from trying to do
a backup...talking about kickin a girl when she's down...bummer.

My backups are getting cobwebbed.

Gonna have to break down and setup amanda or tar or something...
Fire corruption by trying to do xfsdump level 0...ug
Hmmm..that's special...last backup where the file was stored 'bin dir',
xfs restore claims it isn't a directory -- just a large 25 meg file.

that’s not nice.

Next in line is to try new xfsdump/restore, but even if they work, its
still bad that xfs dies so easily -- 

I have no debug output -- it just says found fatal error in file
system and must shutdown the fs.  After that, nada...zilch...
no programs can run...not even sync. (ok, so maybe i should copy
my entire root to another disk...but still....*whine whine whine*...
