We had already added this as a flag (set/unset) when I generalized the
'mds set_max_mds' to be 'ceph mds set <var> <val>'. Switch the snaps
flag to be a key/value to with true/false (similar to the hashpspool
pool flag) since there are fewer users and the var/val approach is more
general.

When run in a shared environment ( as opposed as a machine created for
the purpose of running this test only ), it is important to cleanup
leftovers to avoid poluting the /tmp space. Create a common temporary
directory for all tmp files.

First, add the ability to modify max_file_size. While we are at it, move
to a more sensible interface for adjusting max_mds too.

This will show up on the command line and logs, making it more

The three rules created by build_simple are identical. They are replaced
by a single rule named replicated_rule which is set to be used by the
data, rbd and metadata pools.
Instead of hardcoding the ruleset number to zero, it is read from
osd_pool_default_crush_ruleset which defaults to zero.
The CEPH_DEFAULT_CRUSH_REPLICATED_RULESET enum is moved from osd_type.h to
config.h because it may be needed when osd_type.h is not included.

Creating an erasure pool will crash the OSD because OSD::_make_pg
asserts if the type is not replicated. The tests related to erasure
coded pool creation are removed from qa/workunits/cephtool/test.sh.
The osd-create-pool.sh unit test covers the cases removed from test.sh
more extensively. The intent is to check the interactions with the MON
only, therefore it does not run an OSD and the absence of erasure code
placement group backend implementation is not an issue.

When osd create pool is called twice on the same pool, it will succeed
because the pool already exists. However, if a different type is
specified, it must fail.

It looked like it worked because the wrapper hide the error. The failing
tests are commented out so that the other tests can be used.

Display benchmark results for the default erasure code plugins, in a tab
separated CSV file. The first two column contain the amount of KB
that were coded or decoded, for a given combination of parameters
displayed in the following fields.
seconds KB plugin k m work. iter. size eras.
1.2 10 example 2 1 encode 10 1024 0
0.5 10 example 2 1 decode 10 1024 1
It can be used as input for a human readable report. It is also intented
to be used to show if a given version of an erasure code plugin performs
better than another.
The last column ( not shown above for brievety ) is the exact command
that was run to produce the result so it can be copy / pasted to
reproduce them or to profile.
Only the jerasure techniques mentionned in
https://www.usenix.org/legacy/events/fast09/tech/full_papers/plank/plank_html/
are benchmarked, the others are assumed to be less interesting.

instead of assuming the pool size is 2, query it and increment it to
test for pool set data size. It allows to run the test from vstart.sh
without knowing what the required pool size is in advance:
rm -fr dev out ; mkdir -p dev ; \
MON=1 OSD=3 ./vstart.sh -n -X -l mon osd
LC_ALL=C PATH=:$PATH CEPH_CONF=ceph.conf \

We ran into problems before when we made this a string because a mixed
cluster of mons might forward a client request with the wrong schema.
To make this work, we make the new code understand both the new and
old schema, and also backport a change to emperor and dumpling to
handle the new schema.
For the previous attempt to do this, see:
