[lustre-discuss] PFL error

[Vicker, Darby (JSC-EG311)]

Hello,

We've upgraded to 2.10 and I've been playing with progressive file layouts.  To begin, I'm just setting a test directory to use the following PFL.  

lfs setstripe \
   -E 4M   -c 1 -S 1M -i -1 \
   -E 256M -c 4 -S 1M -i -1 \
   -E -1   -c 8 -S 4M -i -1 .

I then created some files in the different ranges.  

dd if=/dev/zero of=1m.dat   bs=1M count=1
dd if=/dev/zero of=5m.dat   bs=1M count=5
dd if=/dev/zero of=300m.dat bs=1M count=300

When I look at "lfs getstripe" for those files, I can see them hitting the different tiers as they should.  However, I'm seeing this in the lustre logs whenever I create a file in my PFL test directory.

I've searched JIRA but didn't see anything related to this.  Is this concerning?  I can create a new JIRA ticket if that helps.
