I'm trying to add another RAID array into my Fedora 17 installation.
Here is my partition layout:
Yet when I try to built my array, partition 5 on either disk cannot by found
This is my first forray using a GPT disk rather than an MBR disk.
Do I still need an extended partition after 3 primary partitions? I though GPT did away with that.
Any help would be super.
Here is my partition layout:
Code:
[root@firewall ~]# gdisk -l /dev/sda
GPT fdisk (gdisk) version 0.8.5
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Disk /dev/sda: 3907029168 sectors, 1.8 TiB
Logical sector size: 512 bytes
Disk identifier (GUID): AAD0F319-0A3B-4741-9C09-EF93334781A8
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 3907029134
Partitions will be aligned on 2048-sector boundaries
Total free space is 3268468845 sectors (1.5 TiB)
