Some invocations of lvconvert referring to a cache pool LV that was of the wrong type could trigger an internal error. To remedy the problem, lvconvert now offers to convert the LV to a cache pool and when declined, cleanly aborts the operation.

Yes - that should have been trapped cleanly before encountering that internal error. This no longer happens with current upstream code: lvconvert instead offers to convert the LV to a cachepool and when declined, cleanly aborts the operation. The behavior noticed with version 112-1 is as described in Comment #3: [root@virt-133 tests]# lvconvert --type cache --cachepool vg/pool vg/corigin WARNING: Converting logical volume vg/pool to pool's data volume. THIS WILL DESTROY CONTENT OF LOGICAL VOLUME (filesystem etc.) Do you really want to convert vg/pool? [y/n]: n Conversion aborted.
