Ceph » Messengers

The transport layer is async+rdma. And the flag ms_async_rdma_enable_hugepage is set true. Every time running the ceph tool, I get an annoying log like this:

2019-11-18 11:55:15.490 7f0186e80700 0 Infiniband verify_prereq RDMAV_HUGEPAGES_SAFE is set as: 1

The code in ceph/src/msg/async/rdma/Infiniband.cc forces the output for any log level.

if (cct->_conf->ms_async_rdma_enable_hugepage){
     rc =  setenv("RDMAV_HUGEPAGES_SAFE","1",1);
     ldout(cct, 0) << func << " RDMAV_HUGEPAGES_SAFE is set as: " << getenv("RDMAV_HUGEPAGES_SAFE") <<  dendl;
     if (rc) {
       lderr(cct) << func << " failed to export RDMA_HUGEPAGES_SAFE. On RDMA must be exported before using huge pages. Application aborts." << dendl;
       ceph_abort();
     }
   }
