I installed CentOS-7-x86_64-Minimal-1810 on virtual box with 2hdd. I create 3 raid partions for each hdd
/boot (ext4)
/ (ext4)
/swap
After installation I remove first hdd(sda), after I rebooted..it enters in a error state with warnings. Basicaly it does not boot.
I reattach first hdd(sda), and I used the next commands:
sudo grub2-install /dev/sdb
sudo grub2-mkconfig
But it did not worked, I have the same errors.
Boot degraded in raid1 instalation
