Added support for PV grow #1229

Closed japokorn closed 3 months ago

japokorn commented 3 months ago

Storage role requires support for a case when PV has to be resized to fill all available space when its device's size changes (usually on VM).

A new flag grow_to_fill was added, which marks the device for size expansion (all available space it taken). Proper size is determined by LVM, avoiding inaccurate size calculations in blivet.

Added missing tests.
Replaced blockdev.lvm.pvresize(self.pv.device) with blockdev.lvm.pvresize(self.pv.device, 0)
Made grow_to_fill a property that cannot be set unless the device is resizable (raises DeviceFormatError)
Added condition to formats/__init__.py that will prevent bypassing of resize when new size is the same as old one if device is type lvmpv with grow_to_fill set to True
pylint and pep8 fixes
