I really (REALLY) appreciate all your efforts and the work you're doing -- 
this goes to the WHOLE team!! Thanks much!!

I wish I still had the system -- the problem is that I wanted to try your 
"fix" (the "Emacs" fix which I thought could also fix "my" problem,) and since 
I only have one RAID to play with (the other one is active in production use) 
I had to reformat the filesystem. :-(

But I have a "broken" filesystem again -- I get the infamous "No such file or 
directory" message again, altho THIS TIME I don't even get a warning from 
"xfs_repair -n /dev/sdc5." Everything seems fine... :-(((

Unfortunately I don't know ANYTHING about the structure of an XFS filesystem. 
Suppose I have the complete path of a "broken" file (that gives me the "No 
such file or directory" warning,) could you direct me how to use xfs_db to 
further narrow down the problem? I've tried understanding the xfs_db manpage 
but as a layman in XFS structure basics I failed miserably.

I've played around with xfs_db a little bit, and received the following 
output:

xfs_db: blockget -n
dir 1426370585 block 8388614 extra leaf entry 62b7eea7 2a89
dir ino 1426370585 missing leaf entry for 62bdaea7/2a89
user quota id 232, have/exp bc 0/1 ic 0/1
user quota id 1000, have/exp bc 2521011/2521010 ic 19036/19035

Does this -- as I seem to understand it -- already indicate a problem to you? 
How would I further investigate it?

Thanks,

Ralf
