Dell ObjectScale 1.3 Administration Guide

Set up the ObjectScale to ObjectScale Replication

1. Create source and destination buckets on the ObjectScale instances. You must enable versioning on both of the buckets.
2. Attach the bucket policy to the source and destination buckets to ensure that the proper privileges are provided to the account and IAM service role.
3. Use the ObjectScale fedsvc API to GET the provisioned object store:
   1. Set the environment variables:

      IAMSVC_ENDPOINT=$(kubectl get svc | awk '/-iam\s/{print $3}' )

      FEDSVC_ENDPOINT=$(kubectl get svc | awk '/fedsvc\s/{print $3}' )

      TOKEN=$(curl -ik -u root:ChangeMe http://$FEDSVC_ENDPOINT:9500/mgmt/login  | awk '/X-SDS-AUTH-TOKEN/{print $2; exit}')

      TOKEN=${TOKEN//[$'\r\n']}

   2. Use curl to issue the GET objectstores call:

      curl -k -X GET http://$FEDSVC_ENDPOINT:9500/fedsvc/objectstores -H "Content-Type: application/xml" -H "X-SDS-AUTH-TOKEN:$TOKEN"  | xmllint --format -

        </ObjectStore>
      </ObjectStores>

4. Use the ObjectScale API to PUT the replication configuration. In this configuration, you must specify the ObjectScale and object store ID in the target bucket ARN.
   For example:

   SRC_BUCKET_NAME="source1"         # on object scale 1
   DEST_BUCKET_NAME="destination1"   # on object scale 2
   SCALE_ID="OSCIFFFFFFFFEBC3958D"   # object scale 2 object scale id
   STORE_ID="OSTIE5BDD14DBC63185E"   # object scale 2 object store id
   OSR_ROLE_ARN="urn:osc:iam::a7bf6bfe35ac4277a1a8857da98b3226:role/crrRole2"
    
   rm -f $HOME/.osr-rep-config
   cat >> $HOME/.osr-rep-config << EOF
