my name is Mario and I’m following this forum since I’ve switched from SME Server to Nethserver 6.
Now wanted to install latest Nethserver 7.6 on new Hardware but having problems with Bootloader when using Raid 1 on two Harddisks.
Nethserver 6 (and formerly SME Server), which both are based on Centos 6, have installed automatically Raid 1 on two Disks and after Installation there was Bootloader on both Disks,
so that in case of damage you could boot from each of the both disks.
This worked either for small Disks with MBR and even for larger Disks with GPT.
With new Nethserver 7 based on Centos 7 it seems that Bootloader is stored only in the first of the two disks, so that in case of damage of the second disk the system won’t boot.
Anaconda Installer don’t let you make Bootloader on both disks and after Installation tried with “grub2-install /dev/sdb” don’t work for me, still just boot on /dev/sda.
With two GPT Disks Anaconda not even installs, but fails with unknown error every time.
What am I missing ? I’m thankful for every help from you.
