Cannot detach, storage is singular

Hello

I have a charm where I have storage configured but I would like to remove it from the charm. When I try to refresh a deployed charm I get: ERROR cannot upgrade application “geth” to charm “local:jammy/geth-3”: required storage “data” removed So I tried to detach it with juju detach-storage data/0 --force and get: failed to detach data/0: cannot destroy storage attachment data/0:geth/0: cannot detach, storage is singular.

Can someone explain how to detach this kind of storage?

Step by step

  1. Deploy charm with storage configured.
  2. Remove the storage config from the charm
  3. Refresh with new charm where storage is removed.
juju refresh geth --path=./geth_ubuntu-22.04-amd64.charm
Added local charm "geth", revision 3, to the model ERROR cannot upgrade application "geth" to charm "local:jammy/geth-3": required storage "data" removed
  1. Try to remove or detach storage with or without --force results in
failed to detach data/0: cannot destroy storage attachment data/0:geth/0: cannot detach, storage is singular
