错误提示:
Warning: /dev/mapper/ol-root does not exist Warning: /dev/ol/root does not exist Warning: /dev/ol/swap does not exist
进入用救援模式 本机救援模用光盘进救援模式(chroot /mnt/sysimage)
dracut --regenerate-all -f && grub2-mkconfig -o /boot/grub2/grub.cfg
PS:如何在救援模式下联网
ip link set dev ens3 up ip addr add <ip address>/<netmask> dev <device> ip route add default via <gateway ip address>
