Virtfs dir for shell enabled user is not removed on termination of account or removal of shell

Virtfs dir for a jailshell enabled user is not removed on termination of account or removal of shell from his account. This often happens when you enable jailshell only and not normal bash shell. This issue has been there, since I started with hosting industry since 2005 and there is only advice which I want to provide you all.

DON”T EVER DELETE /home/virtfs/user DIRECTORY

Here is one solution which worked for me around 80% of time, which forces the unmount of virtfs of the user. Command is below,

cat /proc/mounts | grep virtfs | grep username |cut -d ' ' -f2 | xargs umount

Good luck!!!
