We (Stanford Research Computing) experienced that exact problem too.
Our tickets are private, but this one is public:
https://jira.hpdd.intel.com/browse/LU-1586

It is definitely a Lustre problem, and Robinhood merely exhibits it.

The workaround was to clean the changelogs by moving
CONFIGS/changelog_[catalog,users] out of the way (on the MDT mounted
as ldiskfs), as explained in
https://jira.hpdd.intel.com/browse/LU-4481
The real fix was in a patch in a later Lustre release, but not sure
exactly which one.

Cheers,
