I have just finished creating an array on our new enclosure and our CentOS 5 server has recognized it. It shows as the full 6tb in the LSI configuration utility as well as when I ran fdisk:
[root@HOST sbin]# fdisk /dev/sdb Note: sector size is 2048 (not 512)
The number of cylinders for this disk is set to 182292. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
Disk /dev/sdb: 5997.6 GB, 5997628227584 bytes 255 heads, 63 sectors/track, 182292 cylinders Units = cylinders of 16065 * 2048 = 32901120 bytes
Device Boot Start End Blocks Id System
I was then created a parition in fdisk and it appeared to work until I formated it (here is the output of the formating)
[root@HOST ~]# mkfs -t ext2 -j /dev/sdb1 mke2fs 1.39 (29-May-2006) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 195264512 inodes, 390518634 blocks 19525931 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=4294967296 11918 block groups 32768 blocks per group, 32768 fragments per group 16384 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968, 102400000, 214990848

When I did a df I got the following (only included the array entry)
[root@HOST etc]# df -h Filesystem Size Used Avail Use% Mounted on ... /dev/sdb1 1.5T 198M 1.5T 1% /home1
I then tried removing it and working with parted.
[root@HOST etc]# parted /dev/sdb Warning: Device /dev/sdb has a logical sector size of 2048. Not all parts of GNU Parted support this at the moment, and the working code is HIGHLY EXPERIMENTAL.

Any suggestions or direction would be appreciated.
