I have a server that had 4 x 1.5TB disks installed in a RAID5 configuration (except /boot is a 'RAID1' across all 4 disks). One of the disks failed recently and so was replaced with a 3TB disk, and the goal is to replace the remaining 3 disks with 3TB disks to get more storage (holds Bacula backups so more storage = more online backup history). Being a 3TB disk I had to make it a GUID Partition Table, and aside from a clean install I did once where Debian installer just did everything for me, I've never used gpt before. I believe I'm supposed to make a partition called the BIOS boot partition... can I store data on here or is it separate to my existing /boot partition? I created such a partition and did grub-install /dev/sda but then on boot from that disk all I get is "GRUB _" (where _ is the flashing cursor). Any hints or links to good online resources would be appreciated. I've googled and can find a bunch of information about it but it's not working for me so I'm missing something somewhere... Thanks James
