Avamar：GSAN 已降級且伺服器處於同步狀態

命令「mccli server show-prop」 會顯示正在同步狀態，因此，節點處於唯讀模式：

admin@AVMR-SRV:~/>: mccli server show-prop

當元數據利用率較高時，將發生同步狀態。在此案例中，中繼資料容量為 99.91%：

admin@AVMR-SRV:~/>: mcserver.sh --status | grep metadata
  metadataUtilization (larger of (nstripes/totalStripesPermitted) or (stripeReserved/(nodeSizeAfterDiskReadOnly * stripeUtilizationCapacityFactor)) * 100): 99.91

發生上述情況是因為執行了不正確的複寫到此 Avamar （GSAN）。還有其他因素可以增加元數據容量。如需詳細資訊，請參閱此文章 Avamar 中繼資料容量解決方案路徑 。
