+ Run RadosModel-based integration tests.
+
+ The config should be as follows::
+
+ rados:
+ clients: [client list]
+ ops: <number of ops>
+ objects: <number of objects to use>
+ max_in_flight: <max number of operations in flight>
+ object_size: <size of objects in bytes>
+ min_stride_size: <minimum write stride size in bytes>
+ max_stride_size: <maximum write stride size in bytes>
+ op_weights: <dictionary mapping operation type to integer weight>
+ runs: <number of times to run> - the pool is remade between runs
+ ec_pool: use an ec pool
+ erasure_code_profile: profile to use with the erasure coded pool
+ fast_read: enable ec_pool's fast_read
+ min_size: set the min_size of created pool
+ pool_snaps: use pool snapshots instead of selfmanaged snapshots
+ write_fadvise_dontneed: write behavior like with LIBRADOS_OP_FLAG_FADVISE_DONTNEED.
+ This mean data don't access in the near future.
+ Let osd backend don't keep data in cache.
+
+ For example::
+
+ tasks:
+ - ceph:
+ - rados:
+ clients: [client.0]
+ ops: 1000
+ max_seconds: 0 # 0 for no limit
+ objects: 25
+ max_in_flight: 16
+ object_size: 4000000
+ min_stride_size: 1024
+ max_stride_size: 4096
+ op_weights:
+ read: 20
+ write: 10
+ delete: 2
+ snap_create: 3
+ rollback: 2
+ snap_remove: 0
+ ec_pool: create an ec pool, defaults to False
+ erasure_code_use_overwrites: test overwrites, default false
+ erasure_code_profile:
+ name: teuthologyprofile
+ k: 2
+ m: 1
+ crush-failure-domain: osd
+ pool_snaps: true
+ write_fadvise_dontneed: true
+ runs: 10
+ - interactive:
+
+ Optionally, you can provide the pool name to run against:
+
+ tasks:
+ - ceph:
+ - exec:
+ client.0:
+ - ceph osd pool create foo
+ - rados:
+ clients: [client.0]
+ pools: [foo]
+ ...
+
+ Alternatively, you can provide a pool prefix:
+
+ tasks:
+ - ceph:
+ - exec:
+ client.0:
+ - ceph osd pool create foo.client.0
+ - rados:
+ clients: [client.0]
+ pool_prefix: foo
+ ...
+
+ The tests are run asynchronously, they are not complete when the task
+ returns. For instance:
+
+ - rados:
+ clients: [client.0]
+ pools: [ecbase]
+ ops: 4000
+ objects: 500
+ op_weights:
+ read: 100
+ write: 100
+ delete: 50
+ copy_from: 50
+ - print: "**** done rados ec-cache-agent (part 2)"
+
+ will run the print task immediately after the rados tasks begins but
+ not after it completes. To make the rados task a blocking / sequential
+ task, use:
+
+ - sequential:
+ - rados:
+ clients: [client.0]
+ pools: [ecbase]
+ ops: 4000
+ objects: 500
+ op_weights:
+ read: 100
+ write: 100
+ delete: 50
+ copy_from: 50
+ - print: "**** done rados ec-cache-agent (part 2)"
