This commit amends the MDS thrasher task to also work on multimds clusters. Main changes: o New FSStatus class in tasks/cephfs/filesystem.py which gets a snapshot of the fsmap (`ceph fs dump`). This allows consecutive operations on the same fsmap without repeated fs dumps. o Only one MDSThrasher is started for each file system. o The MDSThrasher operates on ranks instead of names (and groups of standbys following the initial active). o The MDSThrasher also will change the max_mds for the cluster to a new value [1, current) or (current, starting max_mds]. When reduced, randomly selected MDSs other than rank 0 will be deactivated to reach the new max_mds. The likelihood of changing max_mds in a given cycle of the MDSThrasher is set by the "thrash_max_mds" config. o The MDSThrasher prints out stats on completion, e.g. number of mds deactivated or mds_max changed.

ceph-qa-suite ------------- clusters/ - some predefined cluster layouts suites/ - set suite The suites directory has a hierarchical collection of tests. This can be freeform, but generally follows the convention of suites/<test suite name>/<test group>/... A test is described by a yaml fragment. A test can exist as a single .yaml file in the directory tree. For example: suites/foo/one.yaml suites/foo/two.yaml is a simple group of two tests. A directory with a magic '+' file represents a test that combines all other items in the directory into a single yaml fragment. For example: suites/foo/bar/+ suites/foo/bar/a.yaml suites/foo/bar/b.yaml suites/foo/bar/c.yaml is a single test consisting of a + b + c. A directory with a magic '%' file represents a test matrix formed from all other items in the directory. For example, suites/baz/% suites/baz/a.yaml suites/baz/b/b1.yaml suites/baz/b/b2.yaml suites/baz/c.yaml suites/baz/d/d1.yaml suites/baz/d/d2.yaml is a 4-dimensional test matrix. Two dimensions (a, c) are trivial (1 item), so this is really 2x2 = 4 tests, which are a + b1 + c + d1 a + b1 + c + d2 a + b2 + c + d1 a + b2 + c + d2 Symlinks are okay.
