 |
|
Hello all!
I have RAID controler Areca ARC-1120. He has 8 HD per 400G. Total size bigger then 2T in RAID5. When I do #fdisk -l, fdisk can't show me available space of RAID. I compile drivers, load module, turn on 64bit LBA in RAID BIOS.
# fdisk -l
| Code: | Disk /dev/sdb: 0 MB, 0 bytes
255 heads, 63 sectors/track, 0 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdb doesn't contain a valid partition table |
# dmesg

There is a kernel option called "Support for Large Block Devices" in the "Block layer" section of the kernel configuration. Did you activate it?

And then initialized the RAID in the controller? |

You need to define a GPT disklabel on drives >2TB, or none at all, if your OS lives on another disk
want to use the disk as is, then you can just make an FS on it, mkfs.xfs /dev/sdb, or first throw it in an lvm2 VG and slice it up in LV's -> evms 'could' be your friend for this |
