Symptoms

此問題可能會導致 Avamar 工具節點或單一節點系統上的作業系統文件系統空間異常消耗。

由於 /usr/local/local/avamar/var/mc/server_tmp 和 /usr/local/avamar/var/client 目錄下仍有許多大型、舊檔案，因此 /data01 分割區會填滿。  

例如：
下方輸出顯示 /usr/local/avamar/var/mc/server_tmp 目錄包含 >2700 個 .tgz 檔案，每個檔案通常大小為 66 MB，且從 2015 年 3 月到 2012 年 5 月。

這些記錄檔不受任何保留或旋轉原則的約束。由於大小大，因此可以在 /data01 分割區中耗用大量的空間。當 /data01 接近容量時，Avamar 最終變得無法使用。

Cause

現有的記錄輪替原則不會考慮 /usr/local/avamar/var/mc/server_tmp 或 /usr/local/avamar/var/client/的內容。

Resolution

解決方案：
與支持部門合作，移除多餘的記錄檔，並將系統恢復生產。

解析度：
升級到已修正此行為的Avamar v7.3。
