问题解答

  • 如果达到预留存储库警报阈值、该怎么办?
Recovery Guru上显示以下故障条目、但不会清除快照映像:
 
Failure Entry 1: PIT_GROUP_REPOSITORY_OVER_THRESHOLD-Recovery Failure Type Code: 405
Storage array: array1
Base volume: volume1
Snapshot group: SG
Status: Over Threshold
Used repository capacity: 9,216 GB (90%)
Remaining repository capacity: 1,024 GB (10%)
Repository alert threshold: 75%
 
  • 如果预留容量已满、该怎么办?
取决于"策略"中的全预留容量设置:
清除最旧的快照映像(建议):如果预留容量已满、则会清除Snapshot映像。对基础卷的读取和写入不受影响。
拒绝写入基础卷(保持快照映像有效):写入基础卷失败、但保留快照映像。对基础卷的读取不受影响。
