When a ZVOL is edited, the default compression property "inherit" is removed. Before having made any changes, the property is set to "Inherit (zstd)".
- create ZVOL (compression is set to inherit)
- change ZVOL size (e.g. add 20GiB)
- now the ZVOL size as well as the compression property has changed
When "Edit ZVOL" is selected, the GUI selects "zstd (default level, 3))" rather than "Inherit (zstd)". This is not expected behaviour.
See screenshots. In the process only the ZVOL size was supposed to change. But the size and compression property have changed.
