Lustre discuss - Mar 2009 - File size in a Quota enabled MDT

I have a quick question regarding the file size (as reported by ls 
command) in the ROOT directory of MDT partition:

Are all these files supposed to be 0 size or the size of the file that 
is stored on the OST? In our installation we have a combination of 0 
byte files and really huge(few GB) spare files.

I am running lustre version 1.6.7 and using version2 quota on this MDT. 
I was able to successfully run a "lfs quotacheck" on this file system
as
well.

Thanks in advance.

Currently, the file size on the MDS has very little meaning, and should
be considered an internal Lustre implementation detail, if at all.
