RAID not maintes after reboot

Hi try to install ALmalinux on a new OVH Server.
I follow this guide ( for making a RAID 1 with my 2 SATA disk and mount them with success in /home2 directory.

But this command line “sudo update-initramfs -u” don’t work and after reboot, the server crashed and I need to delete entry in fstab file
Is anyone here can do the install for me.
I paid of course.
Thank you
