      • How to calculate the estimate usable disk space for a hybrid cluster?
      • What is the current capacity, provisioned and available space in the cluster?
      • What is the current thin provisioning gain of the cluster?
      • How does StorPool handle writes?
      • Why are there partitions on all SATA drives used by StorPool?
      • Why the StorPool processes seem to be at 100% CPU usage all the time?

    • Erasure coding
      • Is Erasure Coding enabled for a whole cluster, or is it enabled on a per-volume basis?
      • Are there any expected performance issues that need to be considered?
      • What hardware configurations are supported?
      • What are the supported erasure coding schemes and their respective overheads?
      • Do the required regular snapshots offset some of the space savings?
      • Would I need additional space from triple replication to erasure coding during the conversion?
      • Is there an ideal minimum volume size?
      • How frequently does StorPool recalculate the parity blocks - with each change of the data blocks, or with another method?
      • What is the impact of erasure coding on the network load?
      • Is there a difference between the performance of the different erasure coding schemes?
      • Is there any delay in user operations when regular snapshots are being created?
      • What are the chances that erasure coding can’t recover from a disk failure?
    • How much is the used and free space?
      • How much is the current usage?
        • Short answer
        • Long answer
      • How do we calculate the usage charge?
      • How much space you can provision and how much data you can store on your cluster?
      • Why there is space used in a new/empty cluster?
