The parameter passed to create_bucket was wrong. The right way:
// Create bucket 'mmm-1' in placement target 'fast-placement'
// 'bj' is my region name, 'fast-placement' is my placement target
name.
bucket = conn.create_bucket('mmm-1', location='bj:fast-placement')
// Create bucket 'mmm-2' in placement target 'default-placement'
bucket = conn.create_bucket('mmm-2', location='bj:default-placement')

Hello,
How to configure placement_targets?
Which step is wrong in my following steps?
I want to use different pools to hold user's buckets. Two pools
are created,
one is '.bj-dz.rgw.buckets', the other is
'.bj-dz.rgw.buckets.hot'.
1. Two placement targets are added to region map. Targets tags are
'hdd' and 'ssd'.
----------------begin----------------------------------
"placement_targets": [
{
"name": "default-placement",
"tags": [
"hdd"
]
},
{
"name": "fast-placement",
"tags": [
"ssd"
]
}
],
"default_placement": "default-placement"
}
-----------end------------------------------------
2. Map the placement targets to the ceph backend pools.
--------- begin --------------------------
"placement_pools": [
{
"key": "default-placement",
"val": {
"index_pool": ".bj-dz.rgw.buckets.index",
"data_pool": ".bj-dz.rgw.buckets",
"data_extra_pool": ""
}
},
{
"key": "fast-placement",
"val": {
"index_pool": ".bj-dz.rgw.buckets.index",
"data_pool": ".bj-dz.rgw.buckets.hot",
"data_extra_pool": ""
}
}
]
----------- end --------------------------
3. In order to enable the user create buckets in these two
placement_target/ceph pools, I add two placement_tags for my
user.
---------------------- begin ----------------------------
"keys": [
{
"user": "testuser",
"access_key": "6R2MJWR863EREUDD0KTZ",
"secret_key":
"74eHNNQa1oLBlvZfO2CC2hIU8cobSYxTgeRDtXtH"
}
],
"swift_keys": [],
"caps": [],
"op_mask": "read, write, delete",
"default_placement": "default-placement",
"placement_tags": [
"ssd",
"hdd"
],
---------------------end--------------------------------------
4. Test if it works.
- Test if we can create a bucket 'y-ssd' in 'fast-placement
target'/'pool .bj-dz.rgw.buckets.hot'.
----------------------- begin
---------------------------------
bucket = conn.create_bucket('y-ssd',
location='fast-placement')
----------------------- end
-------------------------------------
- Test if we can create a bucket 'y-normal' in
'default-placement'/'pool .bj-dz.rgw.buckets'.
----------------------- begin
------------------------------------
bucket = conn.create_bucket('y-normal',
location='default-placement')
------------------------ end
----------------------------------------
Result is: ALL these two buckets are created in pool '.bj-dz.rgw.buckets'.
5. In order to test if my 'fast-placement' target works, I change
the user's
'default_placement' to 'fast-placement'. And repeat the
test in step 4.
Reusult is: All those two buckets are created in pool '.bj-dz.rgw.buckets.hot'.
6. conclusion
The user's default placement setting works fine. But the
placement tags seems not work.
Why???
I don't know if this is the right way to use different
placement targets.
thx
