Symptoms

此问题可能会导致 Avamar 应用工具节点或单节点系统上的操作系统文件系统空间异常消耗。

由于 /usr/local/avamar/var/mc/server_tmp 和 /usr/local/avamar/var/client 目录下保留许多大型旧文件，因此 /data01 分区会填满。  

例如：
下面的输出显示 /usr/local/avamar/var/mc/server_tmp 目录包含 >2700 .tgz 文件，每个文件的大小通常为 66 MB，从 2015 年 3 月到 2012 年 5 月。

这些日志文件不受任何保留或轮换策略的约束。由于其大容量，他们可以在 /data01 分区中占用大量空间。随着 /data01 接近容量，Avamar 最终变得不可用。

Cause

现有日志轮换策略不考虑 /usr/local/avamar/var/mc/server_tmp 或 /usr/local/avamar/var/client/ 的内容。

Resolution

解决 方案：
与支持部门合作，删除多余的日志文件，并将系统恢复生产。

分辨率：
升级到已修复此行为的 Avamar v7.3。
