hi all, I have some very basic questions about pools in ceph. According to ceph documentation, as we deploy a ceph cluster with radosgw instance over it, ceph creates pool by default to store the data or the deployer can also create pools according to the requirement. Now, my question is: 1. what is the relevance of multiple pools in a cluster? i.e. why should a deployer create multiple pools in a cluster? what should be the benefits of creating multiple pools? 2. according to the docs, the default pools are data, metadata, and rbd. what is the difference among these?three types of pools? 3. when a system deployer has deployed a ceph cluster with radosgw interface and start providing services to the end-user, such as, end-user can create their account on the ceph cluster and can store/retrieve their data to/from the cluster, then Is the end user has any concern about the?pools created in the cluster? Please somebody help me to clear these confusions. regards Pragya Jain -------------- next part -------------- An HTML attachment was scrubbed...
