feat: PV resize support #438

Closed japokorn closed 3 months ago

japokorn commented 5 months ago

There is an usecase when the physical device size can change (e.g. on VM). We need to be able to change the size of the LVM PV to accomodate that. This adds a new pool parameter grow_to_fill. When set, pool PVs will try to take all available space on their respective devices. Defaults to False.

Requires blivet version that supports this feature. For tests this is checked by using does_library_support script.

Storage role development often relies on blivet library and changes in it. Whether or not is specific feature supported by blivet is usually determined by blivet version. That is a cumbersome process, especially when the feature has not yet been added into blivet and the version has to be guessed.

Added script does_library_support verifies existence of the feature by using python introspection and asking for existence of specific item in the library (e.g. blivet.formats.lvmpv.LVMPhysicalVolume.grow_to_fill). The script is supposed to be used for the tests only.
