A later `docker compose down -v` does not remove a volume that an earlier plain `down` left behind. Say to note its name with `docker inspect` and remove it with `docker volume rm <name>`, and warn that `docker volume prune` deletes every unused anonymous volume on the Docker host. Only a start that gets as far as starting Java creates a `heapdump_*` directory.

Two sentences in the "Server logs and crash files" section that #3258 added are wrong. I pushed the fixes to that branch after it was squash-merged, so they never reached master. apache/hugegraph-doc#509 already has the corrected wording.
docker compose down -vdoes not remove a volume that an earlier plaindownleft behind, because it only removes anonymous volumes of the containers it removes. The README now says to note the volume name withdocker inspectbeforedownand remove it withdocker volume rm <name>. It also warns thatdocker volume prunedeletes every unused anonymous volume on the Docker host.heapdump_*directory, so "each start leaves a directory behind" now reads "each start that gets as far as starting Java leaves a directory behind".ReadWriteMany). The README now says so and suggests a PVC per pod otherwise.Doc - No Need: apache/hugegraph-doc#509 has the same wording.
