[Resolved] RAID/BIOS Booting Issue

Post by l2g » 2016/09/21 14:45:40

Guys,

I flashed my BIOS to the latest and greatest without considering how beautiful my system worked beforehand. Anyway, now i can't boot back into CentOS 7 now.

Code: Select all

I tried to flash back to the original BIOS version i had (which worked great) without success. Yes I truly regret my decision, but what's done is done now. :(

Now if I boot off of the CentOS 7.2 DVD and choose Troubleshooting --> and then Rescue a CentOS system, I can see everything perfectly in /mnt/sysimage which made me feel like I'm not at a total loss (yet). I can see all my RAIDs, access all of my VolumeGroups and everything!

So... my question is:
How can I fix my system so it's bootable again from the /mnt/sysimage, perhaps I'm not at a total loss yet?

Edit:

So as it turns out i just had to stall the boot sequence a bit since the new BIOS seems to take longer to initialize the drives. Thanks to this post.

adding: rd.auto and rootdelay=5 to the kernel parameters and regenerating my grub2 configuration seemed to solve the problem.
