Hi
I have installed SUSE 12.2 as follows
MBR installation and resume 1TB Drive
Root on Raid 1 (2 x 250GB drives)
Another drive of 500 GB
I would like to take out the 1T drive and use it elsewhere
This means that I would need to install the boot on either the Raid or the other drive and I have tried but can not achieve this
So how do i ensure that when the system boots it finds the Grub2 if the 1TB drive has been removed?
Thanks in advance for any pointers
Is it legacy BIOS or UEFI system? If BIOS - which drive becomes boot drive after you remove 1TB? Do you intend to use GRUB2 as MBR (primary) bootloader?
As it is a Phenom XII 4 I presume it is UEFI but not sure
The first of the drives configured as part of the raid 1, though obviously I can change this either by changing the SATA cables or the order in the BIOS
I do not mind if it MBR or not providing it works and I can remove the 1TB to be used elsewhere
Thanks
Do you have /boot/efi mounted? Does “efibootmgr -v” show anything?
No
The command is not known - sudo: efibootmgr: command not found
Thanks for your interest
OK, so you have legacy BIOS boot. In this case just do “/usr/sbin/grub2-install /dev/sdX” where /dev/sdX is the will be bootdisk. If you have enough space after MBR it will embed GRUB2 in post-MBR gap. This assumes your RAID1 disks are partitioned and RAID1 is setup on partition level.
Absolutely brilliant mate
It worked a treat and now I have a 1TB disk to use on another system
Thanks again Arvidjaar
