适用于

  • SnapDrive for Unix ( SDU )
  • 适用于 Oracle 的 Snap Manager ( SMO )
  • SnapManager for SAP (SMSAP)

问题

SnapDrive 无法创建快照,并且在跟踪文件中发现以下错误: sd-trace.log.#
 
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.
 
由于 SDU 需要 7 分钟以上的时间才能失败,因此在 SMO 或 SMSAP 报告中,您会看到以下内容:
 
[ERROR]: EXE-00002: Timeout of 0:05:00.000 occurred while executing command: /usr/sbin/snapdrive snap create -fs /<ORA_MOUNT_POINT> -snapname <smo|smsap>_<SID>_h_<DATE>_<TIME>_1_UUID_0 -unrelated
[DEBUG]: SD-00003: Error creating snapshot: EXE-00002: Timeout of 0:05:00.000 occurred while executing command: /usr/sbin/snapdrive snap create -fs /<ORA_MOUNT_POINT> -snapname <smo|smsap>_<SID>_h_<DATE>_<TIME>_1_UUID_0 -unrelated
 
后面是 Java ProcessExecutionException 跟踪。但是 ,延长 SDU 的超时 时间将显示第一个错误。
