| How many disks can be added to Worker nodes in a BDS cluster? |
| In a worker node with 12 volumes (disks), is it possible to add more storage? |
| Is it possible to resize the disk for each existing worker node to 48TB? |
| How much storage can be added to existing worker nodes? |
| What is the maximum storage which can be added to a worker node with 12 volumes? |
| When increasing storage is it necessary to stop any services in Cloudera Manager (CM)? |

| If adding 3.2 TB will ADD_BLOCK_STORAGE add 1 disk with 3.2 TB or will it partition the existing disks so each has more storage? |
| When increasing storage will adding one disk with all the storage provide better performance than adding several disks each with a slice of the storage? |
| If services need to be restarted is it necessary to wait for the ADD_BLOCK_STORAGE Work Request to complete? |
| Should the cluster be in "GOOD" health before adding storage? |
| If there is no DataNode on a worker node will storage be added to the node? |
