How do I add the second hard drive to the server

LnxNeophyte · 09-23-2012, 11:13 PM

If this is a newbie post please move to that forum

I have a dedicated server that has 2 1TB hard drives, but I only see one 1 TB hard drive, customer support tells me this

"Note because you have installed a non raid system the second drive might be mounted to a different mointpoint."

I want the second 1 Tb hard drive to be extra space
becasue the one 1tb hard drive is at 90%

I have Plesk 10.3.1 but do I have to add the second hard drive on the shell command line? or where in plesk can I add the extra HD.

Plesk gives me this
-----------------------------------------------------
Disk Needs attention
Partition "/" utilization 89.5% used (819 GB of 914 GB) (?)

Partition "/boot" utilization 7.8% used (39.4 MB of 504 MB) (?)

Partition "sda" data transfer 10 B 1.02

Partition "sdb" data transfer 0 B
---------------------------------------------------

what commands do I need to add the second hard drive as extra space to the server, I dont want anything to happen to the main hardrive with 1 tb of content like acidentaly delete it.

Thanks

--->Check out the /etc/fstab file on the server and the man page ( man fstab in the teminal ) . You need to configure the drive for use .

I would also look at permisions and ownership to ensure the only the correct people get access. ( man chmod , usermod ) .

Sample -->

There are a number of ways to configure both from dive indentification ( UID , Dive Connection , Label ) and mounting options. This is my home personal system so it is a very plane jane. You may want to dig in on the subject as it sounds like there are multiple users.

Code:

# 
# /etc/fstab: static file system information
#
# <file system>	<dir>	<type>	<options>	<dump>	<pass>
tmpfs		/tmp	tmpfs	nodev,nosuid,size=4G	0	0

# OCZ : SSD -- /dev/sda
LABEL="Arch" 	/	ext4	defaults	0	1 
LABEL="Home" 	/home	ext4	defaults	0	1 

LABEL="swapfs" 	none	swap	defaults	0	1

# Main Storage

LABEL="E-Space"	/media/E-Space	ext4	defaults	0	1
LABEL="K-9"	/media/K-9	ext4	defaults	0	1  
LABEL="N-Space"	/media/N-Space	ext4	defaults	0	1 


# Back Up
LABEL="Archive-I"	/media/Archive-I	ext4	defaults	0	1
LABEL="Archive-II"	/media/Archive-II	ext4	defaults	0	1

Could you post the output of fdisk -l? Looks like all you need is to configure the mount point.

You also need to format the drive first before it can be mount

I would like to know what are the commands to make sdb1 extra space on my website I just have one website on a dedicated server, sda1 is the boot one that is used right?

Also would like to know at what moment those the second hard drive begin to work, I dont want the main hard drive to get 100% full so I dont get errors, I would like the second hard drive to begin storing data at 94% capacity of the main hard drive.
I hope I can do that.

You need to install, format then edit the /etc/fstab configuration to be able to use.

Here is a link to a fstab tutorial.

Useful tool for formating hard disks is gparted, i noticed your sdb drive has been set under GPT you might want to take a look at this. As jv2112 mentioned you will need to add to the file fstab the command to mount your drive/partitions on boot.

The mount point can be a new folder or directory under your website directory, this is just an idea, i dunno what exactly do you have there, but this is basically what you need. The fstab file is under etc folder, remember to make a backup of that file before you do any changes.
