When creating an LVM volume without specifying a `size` parameter (using the default value `size: 0` from `defaults/main.yml`), the blivet module crashes with a `ZeroDivisionError`.
Root Cause
In `library/blivet.py` line 1127, the `_trim_size()` method performs a division operation:
```python
def _trim_size(self, size, parent_device):
trim_percent = (1.0 - float(parent_device.free_space / size)) * 100
log.debug("size: %s ; %s", size, trim_percent)
...
```
When `size` is `0` (the default value from `defaults/main.yml` line 36), this causes a division by zero error.
```yaml - name: Reproduce ZeroDivisionError hosts: all become: true vars: storage_safe_mode: false storage_pools: - name: test_pool type: lvm disks: - sda # Change to an unused disk on your system volumes: - name: test_volume # No size specified - uses default size: 0 fs_type: xfs roles: - rhel-system-roles.storage ```
patch
```python def _trim_size(self, size, parent_device): # If size is 0, use all available free space (auto-fill) if size == Size(0): log.info("auto-fill volume '%s': using all available free space (%s)", self._volume['name'], parent_device.free_space) return parent_device.free_space trim_percent = (1.0 - float(parent_device.free_space / size)) * 100 log.debug("size: %s ; %s", size, trim_percent) ... ```
