Hi I’m currently trying to setup a mdadm raid array from a live usb .
I have md_mod missing to do so .
For what I understand , I need to add mdadm_udev to the hooks of mkinitcpio.conf and mkinitcpio -P … then reboot to have the new module available.
But it’s a live usb so no persistence.
Do you know how can I resolve this?
(for now my only alternative seem to be to install manjaro on another drive then do my raid array then reinstall the system but I would rather learn how to not do that)
Hi @polyphonus,
If you haven’t yet, check out:
https://wiki.archlinux.org/title/RAID
(I highly doubt I can offer more advice than that, but there it is.)
try with iso USB live manjaro
sudo pacman -Sy mdadmI had already -Suy before.
I did install on a spare disk I had lying around then add mdadm_udev to the hooks . The array is build right now.
I don’t mark this as resolve because I want to know it these is another solution from the live usb.
There is no support in the installer for setting up md/raid nor is there an easy way to do it.
If you did not already see → RAID - ArchWiki
You can setup the disk, configure the raid, assemble the raid - then it should be available in the installer.
Before you reboot you need to copy the configuration to the new root - presumably residing on the raid.
I participated in topic recently where I created a couple of md/raids on a testrig.
This can be done - just read the above article on Arch wiki.
