I have an Infortrend RAID box I'd like to see as one big 6TB partition, but I only can get 2.2TB partitions to work. I was trying to do this with an Adaptec controller but apparently they are only (any of them) 48 bits wide. Does anybody have a working system for SCSI/Centos over 2.2TB?

The last infortrend systems I used supported exporting logical drives of smaller sizes which worked for me. Last I heard you couldn't boot off of drives larger than 2TB with a normal bios(with Intel's EFI I think you can?). nate

I'll second that... we recently put a system online with over 3TB of storage. The only way to create a storage medium that large was to use a gpt disk label and use parted to do the partitioning. mkfs had no problems formatting the partition and it's been working properly for quite some time now.

There is another way too, make the disk a raw PV (no partition table) and use LVM. LVM can handle PVs up to 2^64 in size. Then when creating LVs you only have to worry about what the max file system size is. -Ross ----- Original Message ----- From: centos-bounces at centos.org <centos-bounces at centos.org> To: CentOS mailing list <centos at centos.org> Sent: Thu Jul 24 22:04:42 2008 Subject: Re: [CentOS] Re: 6TB SCSI RAID vs. Centos I'll second that... we recently put a system online with over 3TB of storage.

I'm using a Dell PERC 5/i with the drives configured as simple volumes (aka no hardware RAID). I beleive the PERCs are based on an LSI MegaRAID chipset/controller...
