Performance testing RAID

So after I setup the big RAID I ran some tests on the storage. Here are some commands, make sure you have at least 17GB space available for testing this. Once you run the command look at the time and throughput.

WRITE FILE
dd if=/dev/zero of=/mnt/<mount point>/testfile bs=4194304 count=4096
READ FILE
dd of=/dev/null if=/mnt/<mount point>/testfile bs=4194304 count=4096

linux parted formatting

I am using a very large disk for data and fdisk doesn't work for anything over 2TB in size. This is where parted is need. Here are the command I used to get it partitioned and formatted.

I first ran fdisk -l to figure out the device name. In my case it was sdb
fdisk -l
Then once I got the device name I ran:
parted /dev/sdb
In the parted controls
(parted) mklabel
New disk label type? gpt
Then I ran:
(parted) mkpart                                                           
Partition name?  []?                                                      
File system type?  [ext2]? ext3                                           
Start? 0                                                                  
End? 5997.9GB
Then I exited:
(parted) quit
Now I formatted the new RAID device:
mkfs.ext3 -b 4096 /dev/sdb1
That is all, it takes a while to format large devices, have fun

Apple HFS Support for Linux

I needed to transfer some stuff off of a Mac OS X HFS+ drive from a SATA drive. So in order to do this I install the HFSplus package for Linux
apt-get install hfsplus
I did not try out the Write capabilities but the reading worked like a charm.
