[ceph-users] Re: RGW compression not compressing

Today I tried enabling RGW compression on a Nautilus 14.2.4 test cluster and found it wasn't doing any compression at all. I figure I must have missed something in the docs, but I haven't been able to find out what that is and could use some help. This is the command I used to enable zlib-based compression: # radosgw-admin zone placement modify --rgw-zone=default --placement-id=default-placement --compression=zlib I then restarted the radosgw process to activate the change (there's only 1 RGW in this test cluster): # systemctl restart ceph-radosgw(a)radosgw.$(hostname -s) I verified it was enabled correctly with: # radosgw-admin zone get | jq -r '.placement_pools' [ { "key": "default-placement", "val": { "index_pool": "default.rgw.buckets.index", "storage_classes": { "STANDARD": { "data_pool": "default.rgw.buckets.data", "compression_type": "zlib" } }, "data_extra_pool": "default.rgw.buckets.non-ec", "index_type": 0 } } ] Before starting the test I had nothing in the default.rgw.buckets.data pool: # ceph df | grep default.rgw.buckets.data default.rgw.buckets.data 16 0 B 0 0 B 0 230 TiB I then tried uploading a 1GiB file consisting of all 0s from /dev/zero with both S3 (boto) and Swift (swiftclient) and each time they used 1GiB of data on the cluster: # ceph df -f json | jq -r '.' | grep -A9 default.rgw.buckets.data "name": "default.rgw.buckets.data", "id": 16, "stats": { "stored": 1073741824, "objects": 256, "kb_used": 1048576, "bytes_used": 1073741824, "percent_used": 1.4138463484414387e-06, "max_avail": 253148744646656 } The same thing was reported by bucket stats: # radosgw-admin bucket stats --bucket=bs-test | jq -r '.usage' { "rgw.main": { "size": 1073741824, "size_actual": 1073741824, "size_utilized": 1073741824, "size_kb": 1048576, "size_kb_actual": 1048576, "size_kb_utilized": 1048576, "num_objects": 1 } } What am I missing?
