[DEBUG] Linux resolve df command is stuck

Error phenomenon:

Input df command and the command is stuck
Can not us cd / command to access /(root) directory
Can not us ls / command to display /(root) directory

Analysis:

There may be some network storage disconnected

Solution:

Step One: Use mount command to check if there is any disconnected network storage here

# mount

(Add: At this moment, we can see at least one remote storage mount to local directory. If we cd to this directory, system command prompt will output target is busy)

Step Two: Use unmount command to unmount this disconnected network storage

# umount -f <nfs storage which is stuck>

Or:

# umount -l <nfs storage which is stuck>

Or:

# umount -f -l <nfs storage which is stuck>
