當我嘗試從 Amazon OpenSearch Service 中的手動快照還原索引時,還原失敗並顯示錯誤訊息。
解決方法
Amazon OpenSearch Service 監控 .kibana 索引,並在刪除索引後重新建立該索引。此行為可能會導致還原失敗,並顯示下列錯誤訊息:
{
"error": {
"root_cause": [{
"type": "snapshot_restore_exception",
"reason": "[repository-name:snapshot-name/1A2B34aZQFWQpFOYYJfxmQ] cannot restore index [.kibana] because an open index with same name already exists in the cluster. Either close or delete the existing index or restore the index under a different name by providing a rename pattern and replacement name"
}],
"type": "snapshot_restore_exception",
"reason": "[repository-name:snapshot-name/1A2B34aZQFWQpFOYYJfxmQ] cannot restore index [.kibana] because an open index with same name already exists in the cluster. Either close or delete the existing index or restore the index under a different name by providing a rename pattern and replacement name"
},
"status": 500
}
若要解決此問題,請執行下列步驟:
1. 還原索引並重新命名 .kibana 索引,如下所示:
# restore indices. $ curl -XPOST -H 'Content-Type: application/json' 'https://your-domain-end-point/_snapshot/your-repository-name/your-snapshot-name/_restore' -d'
{
"indices": "*",
"ignore_unavailable": true,
"include_global_state": false,
"rename_pattern": ".kibana",
"rename_replacement": "restored_.kibana"
}
在此範例中,.kibana 索引會重新命名為 "restored_.kibana"。
2. 使用 _reindex API 操作將 "restored_.kibana" 重新命名為 ".kibana",如下所示:
# reindex restored_.kibana to .kibana
$ curl -XPOST -H 'Content-Type: application/json' 'https://your-domain-end-point/_reindex' -d'
{
"source": {
"index": "restored_.kibana"
},
"dest": {
"index": ".kibana"
}
}
您現在可以從手動快照還原索引。
