linux挂载分区失败

如何进行SUSE Linux 10挂载分区后引导出错的修复？

SUSE Linux是一个基于Linux内核的开源操作系统，广泛应用于服务器、桌面和嵌入式系统等领域，在使用SUSE Linux 10的过程中，可能会遇到挂载分区后引导出错的问题，本文将介绍如何进行SUSE Linux 10挂载分区后引导出错的修复，以帮助用户解决问题。

检查硬件连接

1、确保硬盘、光驱等硬件设备已正确连接到计算机上，并使用fdisk -l命令查看硬件设备的信息。

2、如果硬件设备未被识别，可以尝试使用lspci命令查看PCI设备信息，或者检查BIOS设置中的硬件设备配置。

创建并挂载分区

1、使用fdisk命令对硬盘进行分区操作，对/dev/sda硬盘进行分区：

sudo fdisk /dev/sda 

2、按照提示进行分区操作，创建一个新分区或扩展现有分区，完成后，使用w命令保存更改。

3、使用mkfs命令格式化分区，将新创建的分区/dev/sda5格式化为ext4文件系统：

sudo mkfs.ext4 /dev/sda5 

4、创建一个挂载点目录，创建一个名为/mnt/data的目录：

sudo mkdir /mnt/data 

5、将分区挂载到指定目录，将/dev/sda5分区挂载到/mnt/data目录：

sudo mount /dev/sda5 /mnt/data 

修复引导问题

1、备份当前的GRUB引导配置文件：

sudo cp /etc/grub.d/* /boot/grub/grub.cfg_backup/ 

2、使用文本编辑器打开GRUB引导配置文件，使用vi编辑器打开/boot/grub/grub.cfg文件：

sudo vi /boot/grub/grub.cfg 

3、在grub.cfg文件中找到以下行：

set root=(hd0,)
linux /boot/vmlinuz-$(uname -r) root=UUID=<root_uuid> ro quiet splash vga=7880 nokaslr init=/bin/bash 

4、如果存在多个根分区，请确保每个根分区都有一个唯一的UUID，如果没有UUID,可以使用blkid命令为分区生成UUID:

sudo blkid /dev/sdaXNNNNNNNNNNNNNNNN | grep "UUID=" | cut -d' ' -f2> uuid_file.txt 

将生成的uuid_file.txt文件中的UUID替换到grub.cfg文件中的相应行。

5、如果存在多个启动项，请确保每个启动项都指向正确的引导分区，如果有多个根分区，可以使用以下方法添加启动项：

menuentry "Ubuntu" {
  set root=(hd0,)
  linux /boot/vmlinuz-$(uname -r) root=UUID=<root_uuid> ro quiet splash vga=7880 nokaslr init=/bin/bash inst.sh runlevel=5 multiboot=casper netboot=cdrom quiet splash locale=en_US.UTF-8 modprobe.blacklist=nouveau vga_mode=7880 xserver-args=--vga-mode=7880 --vga-fb=screen0 --serverip=<server_ip> --serverport=<server_port> --serverostype=ubuntu --serverosrelease=<server_os_release> --serverarch=amd64 --target-list=http://mirrorlist.centos.org/?release=$(echo $RELEASE_ID | sed 's/([0-9]+).([0-9]+).*/12/g')&repo=os&infra=$(hostname) &arch=$(uname -m) &trusty_installer=1 http://mirrorlist.centos.org/?release=$(echo $RELEASE_ID | sed 's/([0-9]+).([0-9]+).*/12/g')&repo=os&infra=$(hostname) &arch=$(uname -m) &trusty_installer=1 cdrom::cdimage=CentOS-7-x86_64-Server-1708.iso cdrom::url=http://mirror.centos.org/centos/7/os/$basearch xenial_installer=1 mode=install autoboot=on network::configmode=networkmanager systemd::systemunit=network manager systemd::systemunit=network service name='NetworkManager' type='service' systemd::systemunit=network service name='ifupdown' type='service' systemd::systemunit=network service name='firewalld' type='service' systemd::systemunit=network service name='avahi' type='service' systemd::systemunit=network service name='sshd' type='service' systemd::systemunit=network service name='timesyncd' type='service' systemd::systemunit=network service name='chronyd' type='service' systemd::systemunit=network service name='syslog-ng' type='service' systemd::systemunit=network service name='ntpd' type='service' systemd::systemunit=network service name='nfs-common' type='service' systemd::systemunit=network service name='rpcbind' type='service' systemd::systemunit=network service name='idmapd' type='service' systemd::systemunit=network service name='xinetd' type='service' systemd::systemunit=network service name='tftp' type='service' systemd::systemunit=network service name='transmission-daemon' type='service' systemd::systemunit=network service name='postgresql95-postmaster' type='process' systemd::systemunit=postgresql95-postmaster type='socket' socket_type='unixstream' socket_protocol='local' socket_wait_timeout='3600s' socket_user='postgres' socket_group='postgres' socket_directory="/var/run" sysctl kernel.printk="4 4 1 7":7 sysctl kernel.core_uses_pid="1" sysctl kernel.randomize_va_space="2" sysctl net.ipv4.ip_forward="1" sysctl net.bridge.bridge-nf-call-iptables="1" sysctl net.bridge.bridge-nf-call-ip6tables="1" sysctl net.bridge.bridge-nf-call-arptables="1” target=”livecd”} label=”Ubuntu %E%A%8%B%E%A%8%B – Live CD (64 bit)” disabled priority=”100” zapage“” gpgcheck“” gpgkey“http://archive.ubuntu.com/ubuntu bionic main restricted universe multiverse” >> grub.cfg_backup/grub.cfg_backup2 && sudo update-grub && sudo reboot -f && exit 0 || sudo update-grub && sudo reboot -f && exit $?; echo "Grub bootloader has been updated successfully!" || echo "Failed to update Grub bootloader!"; exit $?; sudo umount /mnt/data; sudo chmod a+rw /mnt/data; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit $?; sudo sync; sudo shutdown -r now; exit
