In theory, given that these volume types are tied to the same backend and have the same encryption settings, the retyping process should be as easy as changing the metadata of a volume.\n\nThis is what this patch proposes.","commit_id":"b3f57ca79611ec48c4dd66a9eab6bd653d36ea4f"},{"author":{"_account_id":35467,"name":"Luan Utimura","display_name":"Luan Utimura","email":"luan.utimura@luizalabs.com","username":"lutimura"},"change_message_id":"8c212caadd220783badeeaebe3f9432e07881fdb","unresolved":false,"context_lines":[],"source_content_type":"","patch_set":1,"id":"7fe62808_869f7414","updated":"2026-04-08 13:24:53.000000000","message":"recheck","commit_id":"b3f57ca79611ec48c4dd66a9eab6bd653d36ea4f"},{"author":{"_account_id":35467,"name":"Luan Utimura","display_name":"Luan Utimura","email":"luan.utimura@luizalabs.com","username":"lutimura"},"change_message_id":"4af1fb5e84c4d85185fe8ac677384e948e52a29f","unresolved":false,"context_lines":[],"source_content_type":"","patch_set":1,"id":"09efe8fe_f9aa199d","updated":"2026-04-06 19:34:46.000000000","message":"recheck - cinder-plugin-ceph-tempest failed but doesn\u0027t seem to be related to the patch (instance\u0027s missing)","commit_id":"b3f57ca79611ec48c4dd66a9eab6bd653d36ea4f"}]}
