CentOS raid 10 disk partitioning tutorial

After the CentOS5.5 system is installed, you are ready to partition the remaining space for iscsi sharing. you can use the fdisk-l command to find that four complete disks are displayed! [Root @ file2 ~] # Fdisk-lDisk/dev/sda: 1000.2 GB, 1000204886016bytes255heads, 63 sectors/track, 121601 cylinde

[Root @ file2 ~] # Fdisk-l

Disk/dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065*512 = 8225280 bytes

Disk/dev/sdc doesn' t contain a valid partition table

Disk/dev/sdd: 1000.2 GB, 1000204886016 bytes

Units = cylinders of 16065*512 = 8225280 bytes

Disk/dev/sdd doesn't contain a valid partition table

Use df-h to view the following information:

[Root @ file2 ~] # Df-h
File system capacity used available % mount point
/Dev/mapper/isw_ihhcieff_file2p1
237 GB 3.3G 222G 2%/
Tmpfs 1.9G 0 1.9G 0%/dev/shm

This/dev/mapper should be the entire partition of RAID 10? Remember to display/dev/mapper/isw_ihhcieff_file2 on the disk when installing the system partition. Take this as an example:

[Root @ file2 ~] # Fdisk/dev/mapper/isw_ihhcieff_file2

The number of cylinders for this disk is set to 243201.
There is nothing wrong with that, but this is larger than 1024,
And coshould in certain setups cause problems:
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 ):

You can also partition it! If anything is wrong, should raid partitions be like this?
