Docker lvm resize DESTROYED MY DOCKER

on centos7 i have resized my lvm with these commands:

umount /home/
lvremove /dev/centos/home
lvextend --size +50.00GB -r /dev/mapper/centos-root
lsblk
sed -i ‘/centos-home/d’ /etc/fstab


so, after that worked with my machine properly and without any trouble (more than 4 days of work and development.

BUT today i have restarted my machine and down docker refuse to start, because of this:

[root@host1 ~]# systemctl status docker.service -l
docker.service - Docker Application Container Engine

What to do now? i can’t loose all my data here.

I need to start docker, here or on another machine, what should i do? passing the /var/lib/docker/ folder from this machine to another one, will fix the trouble?
