[Lustre-discuss] MDS activity monitoring

[Andreas Davour]

Hi

I've decided I want to keep an eye on the activity on my MDS, and poking about 
in /proc I found both /proc/fs/lustre/mds/<fsname>-MDT0000/stats and 
/proc/fs/lustre/mdt/MDS/mds/stats which both contain stats about metaops, but 
while similar they are slightly different. 

Now, I'm not really sure I see how they are different, and why there are two 
/proc/fs/lustre/md* directories with stats like that? 

Can somebody who knows something about lustre internals maybe shed some light 
on the layout of the /proc files and where to best look to get a grip on what's 
going on in the file system?
