Bug #23529

Updated by Nathan Cutler about 6 years ago

I'm not sure why this test is in the rados suite, when it tests a CephFS-specific tool(?), but here we are. After some bisecting I determined that one of the following PRs (both CephFS-related, and both already merged) (all CephFS-related) caused a the following regression in jewel 10.2.11 release preparation: 

 https://github.com/ceph/ceph/pull/19141 
 https://github.com/ceph/ceph/pull/19961 
 https://github.com/ceph/ceph/pull/19993 
 https://github.com/ceph/ceph/pull/20312 
 https://github.com/ceph/ceph/pull/20333 <-- this one, because it touches src/tools/cephfs/MDSUtility.cc 

 The regression causes the TmapMigratePP.DataScan test (part of the RADOS API tests) to fail due to the following crash:
