I’ve tried using a Live disc and the first time I did this the main installer saw the md0 - I needed to reconfigure the hardware - and unfortunately after trying again no matter what I do, I cannot get the installer to see the md0 -
I have an sda disk that I want to use as boot, then /root /home /swap on the md0 - can anyone guide me to an instructions that will work for this type of install - I am hopefully looking to improve the file system performance when using the device as well as give it shot of redundancy - any help very gratefully received - I am converting my skills here
How did you create your md0? Previous version of Rocky/CentOS/RH or some other distro?
Does the live installer “see” the component disks of your md0? Or nothing at all?
It sounds like you have a previous installation that you want to upgrade. Can you get back to that installation and, if so, does md0 appear and is normal?
It has been a while (CentOS 7) since I’ve done an install to “real” hardware (not a VM) with existing software RAID 1 disks. I vaguely remember that there is an option when choosing destination drives for the install to select “add drive”. An option within the “add drive” is to pick your existing RAID 1 pair or set up a RAID 1 pair as a new destination. Either way, you then set up your mount point destinations on the RAID 1 pair. The gotcha is that you probably want to have /home not get formatted but everything else gets formatted prior to the install. If you didn’t set up a separate partition for /home with your XFCE install, you can’t preserve /home.
Hi Dave - the solution is to go into Manual mode and there you can create the raid It seems pretty well hidden you have to go through RHEL solutions to find the answer - now to make it boot
That sounds about right. I get to go through the same process here shortly. I have my home server and my desktop with Linux software RAID 1 but on CentOS 7. They get upgraded to Rocky 9 shortly. I seem to recall that getting a RAID 1 partition to be bootable is fairly easy. grub didn’t always understand RAID so you had to use LiLo with RAID 1 but that was back a long time ago.
