What is System Reserved space?

On a QNAP NAS, system reserved space (Sys.Reserved in Storage Manager) consists of the following:

  • QNAP RAID reserved space: stores RAID metadata. 1% of the total capacity of each RAID group is reserved, with an upper limit of 150GB for each group.
  • QNAP storage reserved space: consists of storage configuration data, and extra space to keep the NAS functioning properly. Size is about 70 GB for each storage pool, and 20 GB for each static volume.
  • EXT4 file system metadata: Size is 1% to 1.5% of each user-created volume.
