今天早上使用内网gitlab仓库的时候，发现页面无法打开，ssh也无法连接。
到机房接上显示器，发现如下错误：
Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1)
输入root密码，进入shell界面。
按照提示，使用命令查看日志

在日志中看到，dev-sdc1设备出现问题。
查看磁盘分区情况

很明显，sdc没了，这才记起，当时安装系统的时候，因为多插了一块U盘，当时U盘被识别为sdb，这块磁盘被识别成了sdc。
查看fstab，证明了这一点。
# cat /etc/fstab # # /etc/fstab # Created by anaconda on Tue Aug 8 13:10:48 2017 # # Accessible filesystems, by reference, are maintained under ‘/dev/disk‘ # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/cl-root / xfs defaults 0 0 UUID=a51fd6f8-a756-4e8f-ba44-5589fb99861e /boot xfs defaults 0 0 UUID=7D74-6C54 /boot/efi vfat umask=0077,shortname=winnt 0 0 /dev/mapper/cl-swap swap swap defaults 0 0 /dev/sdc1 /data ext4 defaults 0 0
看来要把写死的磁盘名称更改为UUID。
# blkid /dev/sdc1: UUID="ab4c28b5-1708-483c-973a-40f91d320a9d" TYPE="ext4" ...
修改后的fstab为
# cat /etc/fstab # # /etc/fstab # Created by anaconda on Tue Aug 8 13:10:48 2017 # # Accessible filesystems, by reference, are maintained under ‘/dev/disk‘ # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/cl-root / xfs defaults 0 0 UUID=a51fd6f8-a756-4e8f-ba44-5589fb99861e /boot xfs defaults 0 0 UUID=7D74-6C54 /boot/efi vfat umask=0077,shortname=winnt 0 0 /dev/mapper/cl-swap swap swap defaults 0 0 UUID=ab4c28b5-1708-483c-973a-40f91d320a9d /data ext4 defaults 0 0
尝试重启daemon,仍然弹出同样错误。
# systemctl daemon-reload Error getting authority. Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1)
exit退出shell，再次弹出该错误。
Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1)
不用管，等待几秒，系统已经可以正常启动。
