1. Format the entire drive with a file system, without partitioning the drive.
2. Create partitions smaller that 2 TB, and add them to an Logical Volume Manager (LVM) volume group, then create a logical LVM volume greater than 2 TB. Once the logical volume is created, you can format it with a file system of your choice.
3. You can use the Enterprise Volume Management System (EVMS) volume manager in a similar way as described in step 2 above.
The parted tool can be used to change the partition labeling scheme of a disk.
WARNING: The following procedure will erase all data and partitioning on the block device!
- Open the block device for the disk in parted:
- Create the GPT partition label:
- Set the label to GPT:
- Leave parted:
- Check that the label of the partition is now set to "EFI GPT" by using
fdisk -l /dev/sdaorparted /dev/sdaand press "p".
This problem is caused by the limitations of the disk label (partitioning scheme).
For disks partitioned using fdisk or partitioned as part of a default yast2 installation, the disk label will be ms-dos (the traditional PC disk labeling scheme). With this disk label, the maximum size of a partition is limited to 2 TB.
GPT - GUID Partition Table - is a more recent partitioning scheme which does not have the 2 TB limit for individual partitions.
As of this writing, parted version 1.7.1 can only create ext2, FAT32, FAT16, and linux-swap filesystems. For other filesystem (reiserfs, ext3, OCFS2 etc.), the appropriate mkfs tool needs to be used, e.g.
Status (Last updated: 2009-06-23)
YaST2 in SLE11 has an option to change the disk label and to boot from GPT disks. A feature request for SLE10 SP3 functionality has been logged with Engineering.Additional Reading
The wikipedia article GUID Partition Table provides background on GPT.
