    DELL PERC H700 RAID 5 can't crete partition larger than 2 TB

    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.

    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 (231 bytes). Currently all of our standard file systems have LFS (large file support), which gives a maximum file size of 263 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.


    Table 1.2. Maximum Sizes of Files and File Systems (On-Disk Format)
    File System (4 KiB Block Size) Maximum File Size Maximum File System Size
    BtrFS 16 EiB 16 EiB
    Ext2 or Ext3 2 TiB 16 TiB
    OCFS2 (available in the High Availability Extension) 4 PiB 4 PiB
    ReiserFS v3 2 TiB 16 TiB
    XFS 8 EiB 8 EiB
    NFSv2 (client side) 2 GiB 8 EiB
    NFSv3 (client side) 8 EiB 8 EiB

    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.
