問題

  • WAFLの不整合がRWボリュームで報告され、dump to nullが実行されました。 

 

   [cluster1-02: wafl_exempt02: wafl.raid.incons.buf:error]: WAFL inconsistent: bad block at VBN 39945885441 (vvbn:2995411778 fbn:0 level:0) in public inode (fileid:4201 snapid:946 fixable:0 file_type:2 disk_flags:0x2 error:120 raid_set:1) in volume VOL1@vserver:cad0ac63-9115-11ef-aa35-xxxxxxb9898.

   [cluster1-02: wafl_exempt02: callhome.wafl.inconsistent.block:alert]: Call home for WAFL INCONSISTENT BLOCK

   [cluster1-02: ndmp_session_0: dump.inconsistent.wafl_metadata:error]: Dump of source path (/SVM/vol1), Snapshot copy ID (946): WAFL metadata inconsistent due to disk errors. Aborting the backup.

  • nullへのダンプはフェーズ3で失敗します。
  • 新しいWAFL不整合エラーがfileid:4201のVBN 39945885441でトリガーされます が、ボリュームvol1の新しいスナップショットID で、nullへのダンプが実行されるたびに発生します。 
  • このボリュームは以前DPで、現在ソースクラスタは運用停止されています。
  • "volume file show-inode"コマンドは次のエラーをスローします 

::*> volume file show-inode -vserver svm -volume vol1 -inode-number 4201
   Error: show failed: Unable to get inode information for inode "4201" in volume "vol1" in vserver "svm". Reason: The parent info is missing, it has to yet be loaded.
