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, 1 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 - one of three options have to be chosen :
- all (default)
- none
- metadata
- COPIES - number of copies of the data. As a default, it is set to 1.
