Lustre discuss - Mar 2010 - lfs and df

Hello,

New(ish) to  lustre, but have a quick question that I cannot seem to find
anything about.

In version 1.6, ''lfs df '' shows *all* mounted lustre
filesystems.
On a box that I put the 1.8 client/modules, it only shows the last
filesystem mounted unless I specifically request it (eg: df /work).

Is this normal/by design?

Thanks in advance,

Brian Andrus

What version of 1.8 do you have?  I recall this bug from a while ago,  
but I thought it was fixed.  Testing with 1.8.1.57 (early internal  
version of 1.8.2) I still see this problem.

"lfs df" should behave like "df" in this respect, printing
the stats
for all of the filesystems.  I''ve filed bug 22327 for this issue, and  
it already has a patch for the fix.  The only affected release is 1.8.2.

Cheers, Andreas
