Ceph » rgw

I have tried to get bucket usage via various methods, through curl or while accessing rgw api endpoint HEAD /{bucket}/?usage doesn't return the updated information and I have a doubt it doesn't return the bucket quota instead it returns the user quota.

Reproducing steps:

• While in a vstart cluster after setting the rgw user and permissions such as

./bin/radosgw-admin caps add --uid=testid --caps="users=*;buckets=*;metadata=*;usage=*;zone=*" | jq

• now you can check the status with :
  

  radosgw-admin user info --uid=testid
  

• Create a test bucket using s3cmd and listed the bucket quota
  

  ./bin/radosgw-admin bucket stats --bucket=test-bucket | jq '.bucket_quota'
  

• I have then tried to update the bucket quota using curl with the following script
  

  cat file.json
          {
            "enabled": true,
            "max_size": 12345,
            "max_size_kb": 0,
            "max_objects": 123
          }
  

  
  

  #!/bin/bash
  
  # Usage : rgw_curl.sh $access_key $secret_key $rgw_host:$rgw_port $http_request $admin_resource $query_string   
  access_key=$1
  secret_key=$2 
  rgw_endpoint="$3" 
  http_request=$4
  resource="/admin/$5" 
  query_string=$6
  
  contentType="application/json" 
  dateTime=`date -R -u`
  
  headerToSign="${http_request}
  
  ${contentType}
  ${dateTime}
  ${resource}" 
  
  signature=`echo -en "$headerToSign" | openssl sha1 -hmac ${secret_key} -binary | base64`
  
  curl -X ${http_request} -H "Content-Type: ${contentType}" -H "Date: ${dateTime}" -H "Authorization: AWS ${access_key}:${signature}" -H "Host: ${rgw_endpoint}" "http://${rgw_endpoint}${resource}?${query_string}" 
  

  
  

  bash -x ~/rgw_curl.sh "0555b35654ad1656d804" "h7GhxuBLTrlhVUyxSPUKUV8r/2EI4ngqJxD7iBdBYLhwluN30JaT3Q==" localhost:8000 PUT bucket "quota&uid=testid&bucket=bucket1&quota"|jq
  

*Above script should update the quota values and also enable the bucket quota but if you look at the bucket stats it will be not updated:

endpoint="localhost:8000" 
resource="/bucket1/" 
S3KEY="0555b35654ad1656d804" 
S3SECRET="h7GhxuBLTrlhVUyxSPUKUV8r/2EI4ngqJxD7iBdBYLhwluN30JaT3Q==" 
dateValue=$(date -R -u)

stringToSign="HEAD\n\n\n${dateValue}\n${resource}" 

signature=`echo -en ${stringToSign} | openssl sha1 -hmac ${S3SECRET} -binary | base64`

curl -sk -H "authorization: AWS ${S3KEY}:${signature}" -H "date: ${dateValue}" "http:///${endpoint}${resource}?usage" -v -XHEAD

• but if checked with the cmdline option :
  

  ./bin/radosgw-admin bucket stats --bucket=test-bucket | jq '.bucket_quota'
  
  "bucket_quota": {
          "enabled": true,
          "check_on_raw": false,
          "max_size": 12345,
          "max_size_kb": 13,
          "max_objects": 123
      }
  

From what I understood from the code base for this endpoint it is always returning the user quota values which you can find from

./bin/radosgw-admin user info --uid=testid |jq '.bucket_quota'

{
  "enabled": false,
  "check_on_raw": false,
  "max_size": -1,
  "max_size_kb": 0,
  "max_objects": -1
}
