env

  • centos7.x 2c4g
  • docker-ce

1.copy && umount

//stop docker
systemctl stop docker

cp -av /home /opt/home
umount -l /dev/mapper/centos-home //强制卸载同时要重启
/etc/fstab  //注释

2.set xfs

[root@hot-node2-k8s ~]# df -HT

/etc/fstab  放开注释
[root@hot-node2-k8s ~]# mount -a

3.start docker && check

#clean /var/lib/docker

systemctl daemon-reload 
systemctl restart docker && docker info
