![]() ![]() ![]() Thank you very much and sorry for the long post but maybe someone else will find it helpful. So it kinda works, but is this the correct way to do it?Īm i missing something that could go wrong once i setup the actual SSDs in the server? I also created a file before replacing the drive and this file now shows up regardless of which drive i boot from. So i booted from disk 1 and did: sudo grub-install sudo update-grub /dev/sdbĪnd now it seems to be booting off either drive. Here, choosing disk 1, boots just fine but choosing disk 2 complains about not having a boot loader. Next, I tried rebooting and going in virtualbox boot menu (F12). Now, lsblk looks exactly like it did when i started. So they appear to be identical now so next, i did: mdadm -manage /dev/md0 -add cat /proc/mdstat Sector size (logical/physical): 512 bytes / 512 bytes PC Win Boot Download 4.0 on 76 votes PC Win Boot is a System Rescue disc builder that enables you to make your own boot disk in minutes. dev/sdb2: Created a new partition 2 of type 'Linux filesystem' and of size 10 fdisk -lĭisk /dev/sda: 10 GiB, 10737418240 bytes, 20971520 sectors Download 4.3 on 13 votes Active Boot Disk is a complete and functioning computer operating system on CD, DVD, or USB drive. dev/sdb1: Created a new partition 1 of type 'BIOS boot' and of size 1 MiB.

Create software raid > RAID level 1 / added both partitionsĪfter installation, i can see this: cat /proc/mdstat.Drive 2 free space > add GPT partition > format & mount.Drive 1 free space > add GPT partition > format & mount.In virtualbox, i added two 10GB drives and in Ubuntu server installed, i selected: I found various guides on how to setup a raid 1 on two drives that are also os/boot drives but i didn't have much luck in finding what to do in case one of them fails, respectively how to rebuild a failed RAID 1 drive that's also an os/boot drive. My plan is to have two SSDs in the server setup as RAID 1 that will have Ubuntu installed on them. It will help you to create a bootable password. Instead, you can use an Ultimate Boot CD alternative - Windows Password Key.
