Prompt for device is busy when umount under Linux

  
 

In the recent situation, the server occasionally has a Read-only file system error, ready to uninstall and remount, and the device is busy.

Workaround: fuser -km /home

.

Then it will be OK to uninstall the corresponding disk. Umount /dev/vdc

Remounting will solve the problem of Read-only file system.

Not necessarily all.
