Setting up disk space centos 7

davejones · 06-27-2017, 06:10 AM

Hi all, I've managed to setup an old pc as a dev server but totally new to Linux so looking for some help. The system has 2 disks (2 x 350gb 1 SDD).

Before I go any further I want to allow as much space as possible for webpages but don't have a clue how to do this.

sda
sda1 279.5g
sdb
sdb1 200m /boot/efi
sdb2 1g /boot
sdb3 58.3g
cl -root /
cl -swap [SWAP]
cl -home /home
sdc
sdc1 279.5

Post this output - use [code] ... [/code] tags like I have - it maintains readable layout

Code:

lsblk -f

I can't it's not on a network yet. I've typed the basics of it there is that now good enough? I'm at the point of only just installed Centos 7 so done nothing else. I thought I would investigate getting the Wireless network up while waiting for an answer to this ;-) sorry !

Are you willing to learn&use LVM? IF so, THEN you don't have to decide!
'Toss' a pv drive or 2 (or partitions) (can add more at ANY time!)
into the vg 'pool', then *adjust* lv=fs size(s), 'dynamically'!

What's the model of the PC (&maybe wifi card)?
(spend some time searching LQ/www, to find out 'how to find wifi card model'!)

Do you have -wired- ethernet available? Welcome back & best wishes (aka good luck)

p.s. If&When you can ping 8.8.8.8, http://termbin.com is COOL

The short answer is to ensure you have the disks defined to LVM - this allows you to have a filesystem span across multiple disks (think dynamic disk in Win). Centos should setup like that by default.

Jjanel is right, creating an LVM for the space is the way to go. Allocate it all, but allow for growth so you can extend your LVM if needed. I suggest {mkfs -t ext4} when doing so, so that you can extend when needed. Much more flexibility and what you're looking for.

I think I'll get it connected then come back, some of that I understand but most is going over my head. I do see lvm in the print out though so perhaps it's going to be a easy thing.

I hope you pin that to your cubicle wall ...

Nothing is as easy as it first seems.

Looks legit. I would do an fdisk -l to verify size, then use as needed... What you want to do, depends on how you're going to set up your LVM... What did you have in mind?

I don't know what this means, could you clarify? Whose webpages? Are you a web developer and need to run a site? You'd need to tell us how much space you need for that. Or are you referring to web browser cache? That only needs a few hundred MB or a GB max, you shouldn't concern yourself with browser cache when coming up with your partitioning scheme.

I run web sites that although only simple wordpress sites do hold lots of data in the form of hi-quality images. I currently have have ten of these sites but will look to add more. The server won't be used for anything else so I want all the disk space available to store these images and make the site run as fast as possible. May use Varnish I don't need to worry about regular backups.

Arggghhh - XFS.
Do you only plan on using /dev/sdb for your project ?. What about all that space occupied by NTFS on the other disks ?. Run this and post in [code] tags again pls.

Code:

for i in a b c ; do sudo parted /dev/sd$i "print free" ; done
