Old bootstrap files are not always deleted, disk will be filled over time

[smolin-rh]

Old bootstrap files are not deleted. The disk will be filled over time and this will result in errors like:

• no space left on device or
• The requested volume capacity will exceed the available pool space when the volume is fully allocated

Here an example of old bootstrap file images:
