Cause

BTREE GC 在區塊回收階段運作緩慢。當垃圾容量超過 1 TB，且垃圾檢測率與垃圾區塊回收率之間的差異大於 100 GB 時，會產生此警示。當系統處於此狀態 7 天後，會傳送警示。

Resolution

  1. 透過 putty 工作階段連線至叢集中的其中一個節點。
  2. 確認目前的感應器狀態。
命令：
svc_rest_cmd -i `hostname -i` /vdc/sensor/status/BtreeChunkLevelGC 
# svc_rest_cmd -i `hostname -i` /vdc/sensor/status/BtreeChunkLevelGC
svc_rest_cmd 1.0.10

  1. <尋找目前狀態>，如果設為確定，則錯誤不是作用中，這很可能是誤報警示。請忽略警示，但如果它在下週再次觸發，請向技術支援部門開立服務要求
