upported cache and thin pool lvconversions. - Fix detection of unsupported lvconversion of cache to snapshot. - Improve code for creation of cache and cache pool volumes. - Check cluster-wide (not local) active status before removing LV. - Properly check if activation of removed cached LV really activated. - lvremove cached LV removes cachepool (keep with lvconvert --splitcache). - Always remove spare LV with last removed pool volume. - Support lvconvert --splitcache and --uncache of cached LV. - Option --cache has also shortcut -H (i.e. lvcreate -H). - Refactor lvcreate code and better preserve --type argument. - Refactor filter processing around lvmetad. - Refactor process_each_lv in toollib. - Refactor process_each_vg in toollib. - Pools cannot be used as external origin. - Use lv_update_and_reload() for snapshot reload. - Don't print message in adjusted_mirror_region_size() in activation. - Improve lv_update_and_reload() to find out proper lock holding LV. - Improve search of LV in lv_ondisk(). - Do not scan sysfs in lv_check_not_in_use() when device is closed. - Backup final metadata after resync of mirror/raid. - Unify handling of --persistent option for lvcreate and lvchange. - Validate major and minor numbers stored in metadata. - Use -fPIE when linking -pie executables. - Support DEBUG_MEMLOCK to trap unsupported mmap usage. - Enable cache segment type by default. - Ensure only supported volume types are used with cache segments. -ˆ
