This function allows You to create a new zvol. You have to fill up or choose detailed information related to zvol :
  • NAME - Name the new Zvol
  • SIZE - Size of new Zvol. The unit for this values is GiB (Gibibyte).
In general, if You multiply 1024 ·1024 ·1024 = 1 073 741 824b, which is a result of eqaul 230.
For example, GiB = 1024 × 1 MiB = 1024 × 1024 × 1 KiB = 1024 × 1024 × 1024 × 1 B = 1 073 741 824 ~ 1070 GB
  • PROVISIONING - choose between the : thick provisioned and Thin provisioned (dafault).
  • DEDUPLICATION - choose between :
    • Disbaled (dafault)
    • On
    • Verify
    • sha 256
    • sha 256, verify


  • COMPRESSION - there are several data compression methods - You will see all available methods from the drop-down list. The default compression method is LZ4.You can also choose no compression (NONE).
  • VOLUME BLOCK SIZE  - the default value is 64 KiB. The value can be changed. You can choose between : 0,5 ; 1; 2; 4; 8; 16; 32; 64; 128 [KiB].
  • SYNC  - you can choose between three options :
    • always (default)
    • standard
    • disabled
  • ​LOG BIAS - allows to setup between the latency (default) and throughput.
  • PRIMARY CACHE - one of three options have to be chosen :
    • all (default)
    • none
    • metadata
  • ​SECONDARY CACHE
