Proper Grub Location Not Available?

[Xplorer4x4]

I have a box with a 20GB home partition, a RAID partition, and I forgot how much swap. Anyways, in the past, the home partition showed up, and either the RAID partition or the 2 RAID HDDs showed up individually. Either way, the only partition that shows up on grub is the home partition. If I try to install it there, it errors on me saying:
│ │
│ /dev/md1 │
│ │
│ Do you want to continue anyway? If you do, your computer may not start up properly. │
│ │
│ Writing GRUB to boot device failed - continue?
Should I continue anyway?

I'd say 'no'. You can't (?) install grub to ones /home partition. It either needs to be in the MBR or the / partition, yes?

That's what I thought, so I am unsure how to proceed since I am only offered the home partition.

Edit: I am looking in to that, but for the sake of being more through, the system is a server. Core i7 cpu, 24GB RAM, and 2x2TB Seagate HDDs in RAID0.

Are you using fake raid? (the one that comes with your bios) if so I recommend using Linux software raid instead, it is far more mature.

What is your disk layout like?

sudo parted -l

In order to boot the boot partition must be in a raid 1 array, the rest of the system can be in any other array it likes.

It is typical to separate the boot partition in raid system to do this and have a 1GB partition for a raid 1 array at the start of the disk for /boot and what ever other configuration you wanted after that. Then raid the partition rather then the whole disk.

You still install grub to the device (/dev/sda) not the partition, and I would recommend installing grub to all the disks in the raid array then if one fails you can still boot of the other.

I advise against raid 0 for a server, it is a bit risk storing all that data in a raid 0 configuration as if one drive fails you will lose everything. I would recommend getting another disk and using raid 5 instead, that way you will gain 4TB of usable space and still able to cope with one disk failing without losing data (you could even get 2 additional disks for a total of 4 2TB disks and have 6TB of usable space).

As for RAID config, RAID0 is fine. There is nothing overly important stored on the server. That doesn't mean I would just up and wipe the server, but if it happens., it happens.
