ONTAP 9.7

问题

  • 两个节点上的根卷(vol0)缺少可用空间,但没有任何核心文件或数据包跟踪数据。
  • node-01上的 VLDB 数据增长到千兆字节级别。

XXXX::>set diag
XXXX::*> systemshell * "ls -lh /mroot/etc/cluster_config/rdb/*/_sql/rdb.db-wal"
  (system node systemshell)

  •  node-02 可能由于来自 node-01 的 RDB 数据同步失败(例如,在 BIOS 和 BMC 固件更新之后)而具有损坏标志。

bootarg.rdb_corrupt="7050055000"

  • 如果情况变得更糟,整个集群无法正常工作,CIFS 访问可能会受到影响。
