14 def task(ctx, config):
16 Run RadosModel-based integration tests.
18 The config should be as follows::
21 clients: [client list]
23 objects: <number of objects to use>
24 max_in_flight: <max number of operations in flight>
25 object_size: <size of objects in bytes>
26 min_stride_size: <minimum write stride size in bytes>
27 max_stride_size: <maximum write stride size in bytes>
28 op_weights: <dictionary mapping operation type to integer weight>
29 runs: <number of times to run> - the pool is remade between runs
30 ec_pool: use an ec pool
31 erasure_code_profile: profile to use with the erasure coded pool
32 fast_read: enable ec_pool's fast_read
33 min_size: set the min_size of created pool
34 pool_snaps: use pool snapshots instead of selfmanaged snapshots
35 write_fadvise_dontneed: write behavior like with LIBRADOS_OP_FLAG_FADVISE_DONTNEED.
36 This mean data don't access in the near future.
37 Let osd backend don't keep data in cache.
46 max_seconds: 0 # 0 for no limit
59 ec_pool: create an ec pool, defaults to False
60 erasure_code_use_overwrites: test overwrites, default false
62 name: teuthologyprofile
65 crush-failure-domain: osd
67 write_fadvise_dontneed: true
71 Optionally, you can provide the pool name to run against:
77 - ceph osd pool create foo
83 Alternatively, you can provide a pool prefix:
89 - ceph osd pool create foo.client.0
95 The tests are run asynchronously, they are not complete when the task
96 returns. For instance:
108 - print: "**** done rados ec-cache-agent (part 2)"
110 will run the print task immediately after the rados tasks begins but
111 not after it completes. To make the rados task a blocking / sequential
125 - print: "**** done rados ec-cache-agent (part 2)"
128 log.info('Beginning rados...')
