H--o-l commented on issue #1621: Black matter in shard files URL: https://github.com/apache/couchdb/issues/1621#issuecomment-426745902 @wohali Thanks for looking at it. For the example above, those are documents that seems to be impacted: ```json { "id": "_local/shard-sync-VNaRvSQnMLpUSzV8iZvcow-IOHL5NIdglwNQCT0DL_V0A", "key": "_local/shard-sync-VNaRvSQnMLpUSzV8iZvcow-IOHL5NIdglwNQCT0DL_V0A", "value": { "rev": "0-1" }, "doc": { "seq": 125, "target_uuid": "cef8fe0a2eac1f0f7af0d5e0c56fbbd8", "history": { "couchdb@node1": [ { "target_node": "couchdb@node2", "target_uuid": "cef8fe0a2eac1f0f7af0d5e0c56fbbd8", "target_seq": 127, "source_node": "couchdb@node1", "source_uuid": "2a65d174d772861e4cd085e9e3477298", "source_seq": 125, "timestamp": "2018-10-02T22:21:13.181557Z" } ] } } } ``` ```json { "id": "_local/shard-sync-IOHL5NIdglwNQCT0DL_V0A-gKo_QqiB9XPEFr08HvUC2Q", "key": "_local/shard-sync-IOHL5NIdglwNQCT0DL_V0A-gKo_QqiB9XPEFr08HvUC2Q", "value": { "rev": "0-1" }, "doc": { "seq": 125, "target_uuid": "e0dc03c296d3847efd92e964053e5f1b", "history": { "couchdb@node2": [ { "target_node": "couchdb@node3", "target_uuid": "e0dc03c296d3847efd92e964053e5f1b", "target_seq": 127, "source_node": "couchdb@node2", "source_uuid": "cef8fe0a2eac1f0f7af0d5e0c56fbbd8", "source_seq": 125, "timestamp": "2018-10-02T15:23:00.382192Z" } ] } } } ``` Sadly I can't given you a diff before/after, thoses are the documents in there actual state. By the way, it's seems that restarting couchdb service on our three nodes have a impact on the "black matter", as it increase it (we observe from 8Go of shards to 12Go of shards 1h after service restart, and nothing else happening on the machines). Does that seems possible ? Thanks again for your help !
