Perhaps you are confused and talking about the 2TB limit of any single partition in an msdos disklabel?

GPT disklabels have no such limit, and you can create a gpt disklabel in parted manually at the command line from the opensuse installer, but the grub 0.97 in opensuse won't boot from it (neither do some motherboard bios's so you better try with ubuntu or something first.)

Grub2 understands GPT, but I have found no convenient way to get opensuse installed wirth a GPT disklabel and grub2. Ubuntu can.

I have an Adaptec card with 8 1TB drives set as raid 50 = 5.4 TB. Setting the disk label to GPT looks interesting; how do I accomplish that?

The OS (Suse 10.3) is on a separate system drive so I don't need to boot from the raid.

Thank you,

Have a look at this article. http://www.unixgods.org/~tilo/linux_larger_2TB.html succes, Hans

Thanks Hans, excellent article. Did the following;

parted /dev/sdb GNU Parted 1.8.7 Using /dev/sdb Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) mklabel gpt (parted) print Model: Adaptec RAID50 (scsi) Disk /dev/sdb: 6000GB Sector size (logical/physical): 512B/512B Partition Table: gpt

Number Start End Size File system Name Flags

(parted) mkpart primary xfs 0 6000GB (parted) print Model: Adaptec RAID50 (scsi) Disk /dev/sdb: 6000GB Sector size (logical/physical): 512B/512B Partition Table: gpt

Number Start End Size File system Name Flags 1 17.4kB 6000GB 6000GB primary , , , , , , , , , , , <snip>

At this point from Yast I formatted the partition with XFS;

(parted) parted /dev/sdb print Model: Adaptec RAID50 (scsi) Disk /dev/sdb: 6000GB Sector size (logical/physical): 512B/512B Partition Table: gpt

Number Start End Size File system Name Flags 1 17.4kB 6000GB 6000GB xfs primary , , , , , , , , , , , <snip>

Does this look right? "df -s" shows the partition as;

Filesystem Size Used Avail Use% Mounted on /dev/sdb1 5.5T 1.1M 5.5T 1% /data

Thanks again,

Looks correct, but, why did you even bother with a disklabel or a partition at all in this case? -- Brian K.
