In this case, it’s the ones starting with 0577b983(sda1) and 98d444f0(sdb1). Take note of the UUIDs belonging to the first partition on both drives.
UBUNTU CREATE BOOT PARTITION FREE
Ubuntu’s installer should have taken care of this for you, but feel free to check.įirst, show the partition UUIDs: $ ls -la /dev/disk/by-partuuid/ĭrwxr-xr-x 7 root root 140 Oct 1 22:43. So let’s make sure the ESP is the same on both drives, and that the system will try to boot from either of the hard drives and not just one. If you remove one drive, you might be unable to boot the system. However, while this is fine, there is one potential lurking issue. If the RAID has completed syncing you’ll be able to crash or remove one drive and run off of the remaining hard drive. Remove btrfs-progs to speed up the boot process in case of a drive failure: $ sudo apt purge btrfs-progs Make sure both drives are bootableĬongratulations, you now have a redundant setup! You can check the status of the RAID by running the following: $ sudo mdadm -detail /dev/md0 Save the changes and continue along with the installation. Note that this is without swap, you will have a partition more if you opted to use swap.
UBUNTU CREATE BOOT PARTITION SOFTWARE
When you have followed the steps above, this is what it will look like: What partitioning of disks when installing Ubuntu on software raid might look like. You can use the remaining space if you want to.
UBUNTU CREATE BOOT PARTITION INSTALL
Installing Ubuntu 20.04 with RAIDįirst, let’s install Ubuntu and get a step closer to our goal of RAID1.
UBUNTU CREATE BOOT PARTITION HOW TO
I’ll also add some info on how to handle drive replacements and updates affecting EFI. We’re going to use the efibootmgr tool to make sure both drives are in the boot-list.

Then we’ll make sure that either of the two hard drives can go away without affecting the ability to run or boot. Instead of putting it on a RAID, we’ll install Ubuntu as usual, and then copy the EFI partition over to the second drive.

That’s why we’re going to use another approach. The issue with this is if something external writes to the partition as you can’t be sure which drive has the correct state. That way the beginning of the partition would be the same as without RAID. Well, you could put the EFI partition in a software RAID if you put the metadata at the end of the partition. Things are less straightforward when using UEFI as you need an EFI partition that can’t be on a software RAID. Software RAID has been relatively simple to use for a long time as it mostly just works.
