I need to install Centos on a machine with 3tb raid disk. (3 ware raid card) Could someone in the list suggest a utility for partition this disk. I would like to have the whole disk in 1 partition and format it for ext3. The default partitioning utility doesn't do this. The OS sits on another SATA disk and each time during the installation it doesn't format the full disk which is 3TB. Could someone suggest another disk partitioning utility (other than fdisk) please?

Most *ix systems will work fine with raw dvices. Then in your fstab, use /dev/hda or sda, etc. instead of had1, sda1, ... I've not tried it, but I think LVM might be comfy with this too. But I don't know if they have put code demanding partition information into their software.> > > Could someone suggest another disk partitioning utility (other than > fdisk) please?I've seen gparted recommended on this list. Use google with the "site:centos.org" argument and you'll probably find the details.> <snip sig stuff>HTH -- Bill
As William mentioned the easiest way is to format the drive after the fact. Create an LVM and write it directly onto the drive. Things work great that way. I haven't tried formatting a raw device.

I didn't do it myself so I don't recall all the details, but the gist of it was that in any other partition the tools would not increase the block size above 512, so it was not possible to allocate enough cylinders to fill the disk. (The size could be set to > 512 but then when the partition was created it always ignored the setting and used 512, or something to that effect.) fdisk -l output: Disk /dev/sdc: 2494.9 GB, 2494992220160 bytes 255 heads, 63 sectors/track, 151666 cylinders Units = cylinders of 16065 * 1024 = 16450560 bytes Disk /dev/sdc doesn't contain a valid partition table I don't know whether gparted would have enabled some different magic, I'm not sure anyone here tried using it.
I had this same issue with 'fdisk' when I installed it on a server with 12TB of space RAID'd down to 6TB. Just use 'parted' and it will solve your problems. <http://www.gnu.org/software/parted/manual/> On Sep 23, 2007, at 1:43 PM, Rajeev R Veedu wrote:> I need to install Centos on a machine with 3tb raid disk.
