[HPDD-discuss] ofd_grant_sanity_check errors

Hi, our newly setup Lustre system with 2.5.1/ZFS on the server and 3.12 in-kernel client (a number of patches applied) occasionally shows the following type of errors on the servers. There seem to be no directly noticeable consequences though. Is this something to worry about?
