Today while rolling up new host in my company I hit the following issue after successfully installing CentOS7 on remote iSCSI drive. I just rebooted the machine and after GRUB done it's job I just got:
[ 2.375332] i8042: No controller found [ 2.592960] dracut: FATAL: For argument 'ip=::::localhost.localdomain:eno1: none'\nValue 'none' without static configuration does not make sanse [ 2.593074] dracut: Refusing to continue [ 3.197719] System halted.
The answer is here. Simply installer is broken and it creates broken grub entry for iSCSI nodes.
How to fix this?
There're many ways. I just rebooted the box, entered the grub edit mode and fixed the boot param replacing:
linux16 /vmlinuz-3.10.0-123.el7.x86_64 [...] vconsole.font=latarcyrheb-sun16 ip=::::localhost.localdomain:eno1:none [...]
linux16 /vmlinuz-3.10.0-123.el7.x86_64 [...] vconsole.font=latarcyrheb-sun16 ip=192.168.1.15::192.168.1.1:255.255.252.0:localhost.localdomain:eno1:none [...]
Where 192.168.1.15 is the initiator IP addr and 192.168.1.1 is the gateway IP.
Of course that above is just a way to successfully boot into the system. After boot the grub2.cfg is still broken so now it's the time for a permanent solution:
- Fix above again in /etc/sysconfig/grub
- Rebuild the grub configuration: grub2-mkconfig -o /boot/grub2/grub.cfg
- That's all. Just reboot and confirm it's working fine
