根因分析

  1. 执行以下命令,查询有问题的mount unit。

    systemctl list-units --type=mount |grep failed

    test1.mount             loaded failed failed  /test1
  1. 执行以下命令,查询该unit的状态。

    systemctl status test1.mount

    回显信息如下所示:

    ● test1.mount - /test1
    Loaded: loaded (/etc/fstab; bad; vendor preset: disabled)
    Active: failed (Result: exit-code) since Wed 2019-08-28 15:32:53  CS T; 3min 27s ago
    Where: /test1
    What: /dev/vdb1
    Docs: man:fstab(5)
    man:systemd-fstab-generator(8)
    Process: 4601 ExecUnmount=/bin/umount /test1 (code=exited, status=0/SUC CES S)
    Process: 3129 ExecMount=/bin/mount /dev/vdb1 /test1 -t ext4 (code=exited, status=0/SUCCESS)
    ... ...
    Warning: test1.mount changed on disk. Run 'systemctl daemon-reload' to reload units.

    如回显信息所示test1.mount磁盘发生了改变,需要运行systemctl daemon-reload重新加载units。

    更改/etc/fstab时,必须执行systemctl daemon-reload。在运行该命令之前,systemd不读取fstab并生成装载单元。
