Ubuntu 无需重启即可重新挂载已更改为 ro 的根挂载

由于errors=remount-ro底层 NFS 故障导致我的根挂载被重新挂载为只读。我知道没有什么问题需要我担心。如何在不重新启动服务器的情况下将其重新挂载为 rw？

一些测试：

simon@steve:~$ sudo hdparm -r /dev/sda1

/dev/sda1:
 readonly      =  0 (off)
simon@steve:~$ sudo blockdev --setrw /dev/sda1
simon@steve:~$ sudo blockdev --setrw /dev/sda
simon@steve:~$ sudo hdparm -r /dev/sda1

/dev/sda1:
 readonly      =  0 (off)
simon@steve:~$ sudo hdparm -r /dev/sda

/dev/sda:
 readonly      =  0 (off)
simon@steve:~$ sudo mount -o remount,rw /
mount: cannot remount block device /dev/sda1 read-write, is write-protected

答案1

mount -o remount,rw /mountpoint
