Hi,
I trying to install SLES 11 SP2 in a PowerEdge DELL T310. The server has 3 x 2TB HD’s with PERC H700 RAID 5 witch give me working 4TB of drive.

But I can’t create a partition larger than 2TB. Is there a way to create a partition larger than 2TB?

Hi
Are you using 4K sectors?

Have a read through here as well;

The abstraction of choice for me is to use LVM.

So… if the drive were, let’s say /dev/sdb…

pvcreate /dev/sdb

vgcreate myvg /dev/sdb

lvcreate -l 100%VG -n mylv myvg

and then put your filesystem on /dev/myvg/mylv

No partitions needed.

I’m using the normal DELL PERC H700 RAID 5 sectors.
I read the link you sent but didn’t solve.

I can’t use LVM.
I just need to create a partition larger than 2TB for /home
The problem I described is in the suse installation screen when creating partitions…

I had to create the partitions using ubuntu live CD and choosing GPT format partitions.
Is there a way to do that using SLES 11 SP2 installation? I don’t think so.

Work creating partitions with ubuntu live CD but didn’t work the SUSE linux.

Have you checked the Documentation?
https://www.suse.com/documentation/sles11/

This is from the Linux Enterprise Server 11 SP2 Storage Administration Guide:

1.4. Large File Support in Linux¶

Originally, Linux supported a maximum file size of 2 GB (2[SUP]31[/SUP] bytes). Currently all of our standard file systems have LFS (large file support), which gives a maximum file size of 2[SUP]63[/SUP] bytes in theory. The numbers given in the following table assume that the file systems are using 4 KiB block size. When using different block sizes, the results are different, but 4 KiB reflects the most common standard.

So, the short answer to your question is yes! I don’t know what you are doing that is causing this issue for you but perhaps you can find out from the documentation.
