環境

問題

  • SnapDriveはスナップショットの作成に失敗し、 sd-trace.log.# トレースファイル内で次のエラーが発生します。
 
Operation::addErrorReport: (1) FilerVolume:<STORAGE_IP>:/vol/<VOLUME> 220012 8501:Could not acquire lock file on storage system - more than one instance of snapdrive may be trying to create snapshots.

If no other instance is trying to create a snapshot (even on other hosts),
please delete file /vol/<VOLUME>/.snapdrive_lock on storage system <STORAGE_IP> and retry.
To delete the file, mount the volume <VOLUME> using junction path
and execute the command
'rm $mount_pt/.snapdrive_lock' on host.
 
  • SDUで障害が発生するまでに7分以上かかるため、SMOまたはSMSAPのレポートには次のように表示されます。
