This topic describes how to troubleshoot exceptions that occur on a Linux ECS instance when you delete a mount target in the Apsara File Storage NAS console.
You have mounted a file system on a Linux ECS instance through a mount target. The mount target is deleted before the file system is unmounted, introducing Linux system exceptions. The system freezes, and no response is returned during execution of commands.
- Press Ctrl+C to stop command execution for the Linux ECS instance.
- Run the
mountcommand to view the mount information.Retrieve the mount directory (for example,/mnt/data) from the mount information.
- Run the
umount -f /mnt/datacommand to force the file system to unmount.
unmount-f <Mount directory>Note If the
unmount -f <Mount directory>command fails to unmount the file system, run the
umount -l <Mount directory>command.
After you unmount the file system, you can create a new mount target to mount the file system.
