Symptoms

  • 进入 Data Domain 的备份失败,并显示以下错误:

  • 由于上述错误,某些存储集可能会成功完成,而其他存储集会失败。

Cause

当 NetWorker 尝试写入已关闭的文件句柄时,会出现此问题。
在这些情况下,文件句柄在处于非活动状态 3 小时(默认超时)后被 Data Domain 标记为放弃。
对于繁忙的客户端或大型备份,整合数据可能需要额外的时间,从而导致备份超过默认放弃超时,并导致文件句柄过时。

Resolution

要解决此问题,请增加OST_ABANDON_TIMEOUT值,以便留出更多时间进行备份整合。

通过增加超时值,可以防止过早关闭文件句柄,从而避免文件系统同步期间出现过时的文件句柄错误。

建议超时:8 小时(28,800 秒)
在极少数情况下,它可能会增加到 12 小时(43,200 秒)

警告:此更改需要 SE 模式访问和 Data Domain 文件系统重新启动,这将需要计划内停机时间。要访问 SE 模式,必须通过支持工单联系 Data Domain 支持。
