NFS backup storage not reposponding

[m4s14s]

A problem with NFS server where VM backups are stored hangs the task.

Now we have a backup task that never ends and NFS server content still not active.

It's not possible to stop backup task from the gui.

I stoped backups tasks using kill -9 pid.

But now how can we disconect this NFS backup storage, umount -f says device is busy

What about

umount -l​

OK, it works.
Just need to restart some services to get cluster work properly again.
