centos /dev/md127 problem after reboot

Hello Well today I want to explain about my raid experience. I have to setup a hybrid server on hetzner. I setup the ssd on raid1 using installimage and those other hard drive I have create a raid from linux and mounted them on /raid1 directory . However after reboot, my /dev/md4 disappear and a /dev/md127 appear. To create the raid I have use this fdisk /dev/sdc and /dev/sdd . Make a primary partition and set it up as fd software raid partition . mdadm –create /dev/md4 –level=1 –raid-devices=2 /dev/sdc1 /dev/sdd1 mkfs.ext4 /dev/md4 mkdir /raid1 mount /dev/md4 /raid1 And insert this into fstab file /dev/md4 /raid1 ext4 noatime,rw 0 0 So how to fix this ? First I try to input some information into /etc/mdadm.conf but without luck . It appear that the linux read this late and the centos/ubuntu initalize this from initrd . So in order to fix this some steps have to be done . After reboot try to fill the information into mdadm.conf with ARRAY /dev/md/4 UUID=b3c33fe5:3b078681:e2776e37:4f9fd991 The UUID I have taken from mdadm –detail /dev/md4 First unmount and stop the raid mdadm –stop /dev/md127 After this assemble it again with your desire mdadm –assemble /dev/md4 /dev/sdc1 /dev/sdd1 After this I have copy the /boot/initramfs-2.6.32-573.3.1.el6.x86_64.img to a backup file ( initramfs-2.6.32-573.3.1.el6.x86_64.img-back ) in case something go wrong. After this run dracut –force If is centos 5 or less you have to copy initrd file and to recreate use mkinitrd -f -v /boot/initrd-$(uname -r).img $(uname -r) On ubuntu you have to run sudo update-initramfs -u And restart the...

Well today a client with hetzner server have a problem. Both hard from raid have failed. One is lost forever and one is with bad. After I have run recover hard for rebuild in raid the server still didn’t boot up. My /dev/sda was faulty and replaced but server was stcuk and didn’t start . I have to rebuild grub , the hetzner wiki have a tutorial but is not exactly . So .. in order to start the server reboot in rescue system. Then my partition table was something like this /dev/md1 ( /boot ) /dev/md3 (/var) and /dev/md4 (/) I run this in this order mount /dev/md4 /mnt mount /dev/md1 /mnt/boot mount /dev/md3 /mnt/var After this chroot-prepare /mnt chroot /mnt grub-install /dev/sdb grub-install /dev/sda And the server was up and running .
