• When you create an archive with block or object storage type as a file, note that disk must not be full completely. For the correct operation of the system, it is necessary to leave some space free. General recommendations for arranging free space:
  

  Info
  title Note
  When you create a local archive with block storage type as a partition (logical disk), the disk can be filled completely.

  • If archive size is less than 1 TB, you need about 100 MB of free space.
  • If archive size is between 1 TB and 10 TB, you need about 1 GB of free space.
  • If archive size is larger than 10 TB, you need about 10 GB of free space.
• For archives with object storage type, we do not recommend using an archive as a single volume of large size. You must split the archive into several volumes and place them on different physical devicesplacing archive volumes or archives on the same physical device. If placing several archives on one physical disk is unavoidable, free space must be N times larger than the volume of all archives (N is the number of archives). We recommend splitting the archive into several volumes and placing them on different physical devices to improve the reliability and performance of storage. 
• We recommend creating archive volumes of no more than 30 TB each.
