♞CentOS Read-only file system 错误修改

最近一次因为树莓派非正常关机引起系统错误

[root@MiWiFi-R1CM-srv ~]# systemctl status httpd
● httpd.service - The Apache HTTP Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)
   Active: failed (Result: resources)
     Docs: man:httpd(8)
           man:apachectl(8)

首先用使用fdisk查看一下磁盘分区

[root@MiWiFi-R1CM-srv ~]# fdisk -l

Disk /dev/ram0: 4 MB, 4194304 bytes, 8192 sectors
	……
I/O size (minimum/optimal): 4096 bytes / 4096 bytes


Disk /dev/mmcblk0: 62.5 GB, 62537072640 bytes, 122142720 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

        Device Boot      Start         End      Blocks   Id  System

使用e2fsck修复磁盘错误

[root@MiWiFi-R1CM-srv ~]# e2fsck -y /dev/mmcblk0p3

使用reboot重启系统

[root@MiWiFi-R1CM-srv ~]# reboot
