This method should exclusively be invoked from a Vert.x EventLoop thread

这个错误通常是在非 EventLoop 线程中尝试访问 Vert.x API 时发生的。Vert.x 的 API 仅限于在 EventLoop 线程中使用。解决方法是将代码块包装在 runOnContext 方法中,以确保它在 EventLoop 线程中执行。例如:
```
Vertx vertx = Vertx.vertx();
vertx.runOnContext(event -> {
// 在这里执行需要在 EventLoop 线程中执行的代码
});
```

Can't open /dev/sdb1 exclusively. Mounted filesystem?
This error message suggests that the device `/dev/sdb1` is already mounted and in use by another process, preventing you from accessing it exclusively.
To resolve this issue, you will need to unmount the device first before attempting to access it exclusively. You can do this by running the following command:
```
umount /dev/sdb1
```
If the device is still in use by another process, you may need to identify the process and terminate it before you can unmount the device. You can use the `fuser` command to identify the process that is using the device, and then terminate it using the `kill` command.
Once you have unmounted the device, you should be able to access it exclusively without encountering the error message.
pvcreate Can't open /dev/sdc exclusively. Mounted filesystem?
这个错误提示表明/dev/sdc设备已经被挂载了,无法进行pvcreate操作。你需要先卸载该设备,然后再进行pvcreate操作。可以通过以下命令卸载该设备:
```
umount /dev/sdc
```
如果该设备被其他进程占用,你需要先找到占用该设备的进程,然后将其杀死,例如:
```
fuser -m /dev/sdc
kill -9 <PID>
```
其中,<PID>为占用该设备的进程ID。完成之后,你就可以再次尝试进行pvcreate操作了。
