T: bug C: installer r4.1-dom0-cur-test P: default

**Qubes OS version** R4.0 **Affected component(s) or functionality** lvm, i…nstaller **Brief summary** Installer (anaconda) leaves some space not allocated (~20% now, previously less). This is supposed to be used by LVM autoextend to automatically enlarge data or metadata volumes according to the needs. But autoextend is disabled. **To Reproduce** _Steps to reproduce the behavior:_ _1. Install Qubes 4.0_ _2. Check LVM pool size and settings_ _3. See ~20% not allocated, but `thin_pool_autoextend_threshold` in `/etc/lvm/lvm.conf` set to 100 (effectively disabling the feature)_ **Expected behavior** When free space is left, autoextend should be enabled to make use of it. **Actual behavior** Autoextend not enabled. **Additional context** This is yet another countermeasure for filling up metadata volume. **Relevant [documentation](https://www.qubes-os.org/doc/) you've consulted** #3243 **Related, [non-duplicate](https://www.qubes-os.org/doc/reporting-bugs/#new-issues-should-not-be-duplicates-of-existing-issues) issues** _A list of links to other bug reports, feature requests, or tasks in the qubes-issues tracker (or "none" if you didn't find any).
