How does your regionmap look like? Is it updated correctly on all
zones?


Regionmap listed below - checking it on all 4 zones produces exactly the
same output (md5sum is same):


         {
             "key": "us",
             "val": {
                 "name": "us",
                 "api_name": "us",
                 "is_master": "true",
                 "endpoints": [
                     "http:\/\/ceph2:80\/",
                     "http:\/\/ceph1:80\/"

Note that you have ceph1:80 specified as an endpoint to the region.
This is then used for the bucket creation. This one should only
include the master endpoint.



Cool, thanks - I was unclear about which endpoint(s) should be listed
for a region. I'll change 'em and try again.



Amending region definitions as indicated gets progress:

Tue Feb  3 02:19:29 2015
/bucket1/
2015-02-03 02:19:29.403362 7fe34cf69700 15 generated auth header: AWS eu-east key:4Rd9WaeJDenXSAq8GCEO1LqmcgQ= 2015-02-03 02:19:29.403373 7fe34cf69700 20 sending request to http://ceph2:80/bucket1/?rgwx-uid=markir&rgwx-region=eu


But the final result is a 403. Checking the log on ceph2 shows:

Ah, it doesn't know about my *eu* system users in the us region - after creating those I can then add the bucket in the eu region ok. Yay!

Also it would appear that it has worked as intended (using ceph df to check):

(us region)
ceph2 $ ceph df|grep bucket
.us-east.rgw.buckets.index 114 0 0 18372M 2 .us-east.rgw.buckets 115 12 0 18372M 1 .us-west.rgw.buckets.index 127 0 0 18372M 0 .us-west.rgw.buckets 128 0 0 18372M 0


(eu region)
ceph4 $ ceph df|grep bucket
.eu-east.rgw.buckets.index 97 0 0 18360M 2 .eu-east.rgw.buckets 98 12 0 18360M 1 .eu-west.rgw.buckets.index 110 0 0 18360M 0 .eu-west.rgw.buckets 111 0 0 18360M 0


i.e: bucket index metadata sees two buckets, but there is only one in each region.


Thanks for your help!

Cheers

Mark
