I'm trying to install ubuntu Server to a RAID5 array. I have three, 3Tb disks, each with a GPT partition table. I have set up my partitions as follows:
/dev/sda 1. 512 Mb physical RAID volume 2. 3 Tb pysical RAID volume /dev/sdb 1. 512 Mb physical RAID volume 2. 3 Tb physical RAID volume /dev/sdc 1. 512 Mb physical RAID volume 2. 3 Tb physical RAID volume
The raid volumes are grouped into two
1. 1.5 Gb RAID5 (mount point: swap) 2. 6.0 Tb RAID5 (mount point: /)
Installation proceeds normally until it is time to install GRUB2. I get an error that reads:
Unable to install GRUB in /dev/sda Executing `grub-install /dev/sda` failed. This is a fatal error.
Why is this happening and what can I do to fix it?
