If you man fdisk fdisk doesn’t understand GUID Partition Table (GPT) and it is not designed for large partitions. In particular case use more advanced GNU parted(8). try parted and let use know if that works.. im coming up on a large BOD setup soon Message: 3 Date: Sat, 9 Feb 2008 23:42:46 +1300 From: "Geofrey Rainey" <Geofrey.Rainey@xxxxxxxxxx> Subject: RE: Disk partitions and LVM limits To: "General Red Hat Linux discussion list" <redhat-list@xxxxxxxxxx> Message-ID: <FCFF2EC7A020964FBC98B17F17A88AC453D246@xxxxxxxxxxxxxxxxxxxxxxxxxx> Content-Type: text/plain; charset="us-ascii" You could change the sizing of the 5.4TB logical partition into smaller logical partitions Of 2TB in size, make each of these a physical volume and add them to a volume group, then create a logical volume from that volume group. I don't know if this 2TB limit will affect this procedure though. -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Peter Blajev Sent: Saturday, 9 February 2008 7:59 a.m. To: Red Hat List Subject: Disk partitions and LVM limits Hi, I've got a DAS DELL MD1000 with a bunch of SATA drives in RAID 5 configuration with total space of 5.4TB. This box is attached to a CentOS5 system (kernel 2.6.18-53.1.6.el5). Any idea how to make this space usable? Is there a limit how big a partition can be? What is the work around? Is there a limit how big a file system ca be? I've tried to partition it but no matter how bug partition I create fdisk spits out these messages on the console: --- sdb: very big device. try to use READ CAPACITY(16). SCSI device sdb: 10248519680 512-byte hdwr sectors (5247242 MB) sdb: Write Protect is off --- I decided to not partition the drive and use LVM but the physical volume stopped at 2TB. So, right now I can't use LVM because of this 2TB limit and I'm not sure if I partition the drive how good these partitions are because of the the message from fdisk. Any help or idea is highly appreciated.
