Looking at the doc again, it is true that it is not clear about this
point...
We'll try to make it more explicit in the next doc update.
Sorry about that.

OK.Thanks for the update. I was reading documentationunder Software
Presentation , section 1.1"With Lustre v2, scanning is no longer
needed thanks to Lustre MDT Changelog mechanism"...I ran an initial
scan with robinhood --S --once and looks much better now.

Hi Matthew,
An initial scan is required to make robinhood aware of existing
filesystem contents. Did you run one?
Then the changelog keeps robinhood DB updated.
Also, you have to take care of your MDS changelog mask configuration,
else robinhood will not get all the updates it needs.
If it is not set persistently (as far as I can remember, using "lfs
setparam -P" which is the replacement for "lfs confparam")
is will be lost each time you restart your mds.
"Entry has incomplete path in DB: parent_id='0x20000373c:0xc2ef:0x0',
relative_path='illum_s_1.H@'"
This can obviously be explained if there were no initial scan.
This can also sometimes appear with specific "create/rename" patterns
because of a bug in rbh 2.5.2
which is now fixed in master branch and will be part of next robinhood
2.5.3:
