[lxc-users] What's happened if I mount existing mounted partition in a running lxc container.

[Скубриев Владимир]

For example:

I have a running lxc container
with mounted lvm logical volume filesystem /dev/sysraid/server_data througth /var/lib/lxc/container/fstab

At the host system, under root account I'am made a mistake when typing mount command. 

I mounted, and then very fast un mounted already mounted partition.

Anything can happen with that partition and their data?

How to prevents this mistakes or protect youself from them?

Thank you.
