Is there any way to unmount an ext4 filesystem without shutting down?
I can do it easily by going to single-user mode or removing the filesystem from /etc/fstab and rebooting but both of these require the system to be shut down.
However it seems to be impossible otherwise because the journalling process makes the filesystem busy. Is this right?
