Centos 6.2 64bit. –  Emre Bozlak Dec 4 '12 at 13:44
    
Unless your machine support EFI (instead of BIOS) you wont be able to boot from a drive larger than 2.2TB. If you do have EFI, make sure your RAID HBA's firmware is completely up to date. Also, what RAID HBA are you using? –  Chris S Dec 4 '12 at 14:04

It is not recommended to make a RAID 5 partition of this size...unless you do not care about the data or may loose the data and do not care. Upon the loss of a disk in this system, it is likely you would encounter another unrecoverable error which would prevent the RAID from rebuilding correctly. You might want to do a search for problems with RAID 5 and array of this size. If I recall correctly, you may not even want a RAID 6 for such a device.
