[lustre-discuss] Slow release of inodes on OST

When I create a large number of files on an OST and then remove them,
the used inode count on the OST decreases very slowly, it takes several
hours for it to go from 3M to the correct ~10k.
(I'm running the io500 test suite)
Is there something I can do to make it release them faster?
Right now it has gone from 3M to 1.5M in 6 hours, (lfs df -i).
These are SSD based OST's in case it matters.
