Hello all, For the past two weeks I've been in the process of resurrecting the multimds test suite which has not be regularly exercised in some time. This is part of the initial work to have multiple active metadata server configurations regularly tested and supported. Recent multimds test runs can be viewed (as always) at [1]. The first stage of this work is to organize and process the current failures into bug reports [2-8]. These are just the currently known failures we have coming from our tests. Some failures like #16926 [8] are particularly widespread and probably masking many other failures. As the team works on these bugs, the next steps are to expand our test coverage of the multimds suite. So far we have planned: o [9] Testing MDS cluster size changes under load. o [10] Testing directory fragmentation and inode export under load. This test will be exercising the balancer in the MDS. o [11] Testing cluster recovery during failures migration/fragmentation. o [To Be Filed] Testing rename with authoritative inodes/directories varying across multiple MDSs. o [To Be Filed] Integrate recently added tests in the fs suite into the multimds suite. Please let us know if you have any comments or questions.
