文件系统只读挂载

journalctl -u docker
Oct 11 13:28:53 localhost.localdomain dockerd[1035]: chmod /var/lib/docker: read-only file system

操作系统异常关机之后重新启动文件系统会在特定的情况下被只读挂载

mount 命令可以查看到挂载参数为 ro

[root@localhost ~]# lsblk

解决方法

如果文件系统没有损坏, 那么重新挂载就好了

mount -o remount rw /

如果文件系统有损坏, 那么使用相应的工具修复之后再挂载.

unknown service containerd.services.namespaces.v1.Namespaces

failed to start daemon: failed to dial "/run/containerd/containerd.sock": unknown service containerd.services.namespaces.v1.Namespaces: not implemented

这个问题是由于docker依赖的服务containerd状态异常, 重启就可以了


systemctl stop containerd
systemctl start containerd

#启动docker
systemctl start docker.service
