      Hi,

      After about 2 months of production, our new Lustre 2.9-based system (Oak) started to show the following Lustre errors in the logs on our OSS servers, just a few days ago:

      Jun 22 10:45:06 oak-io1-s1 kernel: LustreError: 26807:0:(ofd_grant.c:641:ofd_grant_check()) oak-OST0014: cli 1b1c6319-5ec1-dbcc-f6e7-f85575c95c4c claims 131072 GRANT, real grant 0

      Attaching an lquota subsystem debug trace on one of the OSS and a splunk graph showing that these messages are actually new. I first thought that this could be related to LU-9671 but it might not be after all.

      Thanks,
      Stephane
