Hi Yehuda/RGW experts, I have one cluster with RGW up and running in the customer site. I did some heavy performance testing on that with CosBench and as a result written significant amount of data to showcase performance on that. Over time, customer also wrote significant amount of data using S3 api into the cluster. Now, I want to remove the buckets/objects created by CosBench and need some help on that.
I ran the following command to list the buckets. “radosgw-admin bucket list” The output is the following snippet.. "rgwdef42", "rgwdefghijklmnop79", "rgwyzabc43", "rgwdefgh43", "rgwdefghijklm200", …………………….. …………………….. My understanding is , cosbench should create containers with “mycontainers_<n>” and objects with format “myobjects_<n>” prefix (?). But, it’s not there in the
output of the above command. Next, I tried to list the contents of the different rgw pools.. rados -p .rgw.buckets.index ls .dir.default.5407.17 .dir.default.6063.24 .dir.default.6068.23 .dir.default.6046.7 .dir.default.6065.44 .dir.default.5409.3 ……….. ……….. Nothing with rgw prefix…Shouldn’t the bucketindex objects having similar prefix with bucket names ? Now, tried to get the actual objects… rados -p .rgw.buckets ls default.6662.5_myobjects57862 default.5193.18_myobjects6615 default.5410.5_myobjects68518 default.6661.8_myobjects7407 default.5410.22_myobjects54939 default.6651.6_myobjects23790 ………………………. ……………………… So, looking at these, it seems cosbench run is creating the .dir.default.<n>* buckets and the default.<n>_myobjects<n>* objects (?) But, these buckets are not listed by the first “radosgw-admin” command,
why ? Next, I listed the contents of the .rgw pool and here is the output.. rados -p .rgw ls .bucket.meta.rgwdefghijklm78:default.6069.18 rgwdef42 rgwdefghijklmnop79 rgwyzabc43 .bucket.meta.rgwdefghijklmnopqr71:default.6655.3 rgwdefgh43 .bucket.meta.rgwdefghijklm119:default.6066.25 rgwdefghijklm200 .bucket.meta.rgwxghi2:default.5203.4 rgwxjk17 rgwdefghijklm196 ………………. ………………. It seems this pool has the buckets listed by the radosgw-admin command. Can anybody explain what is .rgw pool supposed to contain ? Also, what is the difference between .users.uid and .users pool ? Appreciate any help on this. Thanks & Regards Somnath |
