|
|
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
|
|
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
|
|
ruleset-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)"
