Description

Current build installed; https://build.hpdd.intel.com/job/lustre-reviews/38245/
This issue has persisted for the last two builds.
After mounting the filesystem, all nodes report NOT HEALTHY in /proc/fs/lustre/health_check.

1. pdsh -g server 'lctl get_param health_check' |dshbak -c
   ----------------
   lola-[2-11]
   ----------------
   health_check=healthy
   NOT HEALTHY

The filesystem otherwise operates normally, jobs run, results are created.
We were using the health_check as part of our monitoring - this has been discontinued.
We are uncertain as to the cause, as all operations we can test work fine, and no errors are reported.
