a little while ago, one of the GPT Partitioned hard disk had gone faulty in a Mirror RAID and is now successfully replaced.
here is how I did that.
1) created identical partition table on the new disk.
2) attached the mirrors using md commands.
The whole procedure is given below:
/dev/sda is replaced here
New Disk is replicated using sgdisk
Created and Attached the mirrors to the raid system.
Now I have a good mirror in place. Now the question is that when I try to boot the system using the New Hard disk /dev/sda from the BIOS, it comes to halt and nothing shows up except blinking cursor on blank screen and I have to reboot the system to select the /dev/sdb disk to boot from. This is happening for the normal reboot as well, in such a way that i have to select the disk manually everytime the system is rebooted.
Can someone please guide how the other disk can be grub-recorgnized and how I can make a seamless reboot..
Assuming you are using GRUB2, pre-EFI firmware, i.e. a BIOS, and a GPT disk, do you see any sign of a BIOS Boot Partition Table? Partition type should be EF02.
Can you please suggest what that means to Populate the BIOS Partition. I'm not aware of this mechanism.
Regards,
Nasir
