适用于

  • 适用于 Oracle 数据库( SCO )的 SnapCenter 插件 4.3 , 4.4
  • SAN 或 VMDK 配置

问题

  • 运行 SCO 验证作业时,系统会在 /etc/systemd/system 中创建指向 /dev/null 的符号链接(符号链接),但不会自动将其删除。
  • 符号链接的名称包含 "var-opt-snapcenter-sco-backup_verify" ,如以下示例所示。

示例:

[root@rhel2 system]# ls -l /etc/systemd/system/var-opt-snapcenter-sco-backup_*
lrwxrwxrwx 1 root root 9 Dec  9 02:04 /etc/systemd/system/var-opt-snapcenter-sco-backup_verify-rhel2_demo_netapp_com_orcl_rhel2_12-09-2020_02.02.15.6102_0-orcl-1.mount -> /dev/null
lrwxrwxrwx 1 root root 9 Dec  9 02:11 /etc/systemd/system/var-opt-snapcenter-sco-backup_verify-rhel2_demo_netapp_com_orcl_rhel2_12-09-2020_02.09.00.3082_0-orcl-1.mount -> /dev/null
lrwxrwxrwx 1 root root 9 Dec  9 02:30 /etc/systemd/system/var-opt-snapcenter-sco-backup_verify-rhel2_demo_netapp_com_orcl_rhel2_12-09-2020_02.28.05.0975_0-orcl-1.mount -> /dev/null

 

  • spl_<verification_job_id>.log 表示已执行 SCO systemctl mask以创建符号链接。
