I am working on my CompTIA Linux+ cert. Watched all the videos on this site. I created CentOS and Ubuntu server to practice on both flavors. I decided to play with Wordpress, PHP, and MySQL along the way.
I am considering getting some HP 7.2K 4TB drives and doing SAS Hardware RAID 10 of 8TB. It would cost about $600 for 4 of them. I have a DL320e Gen8 server with hardware RAID and a SD card with VMWare 6 U3 on it.
I moved everything off my Ubuntu web server into Wordpress on a CentOS 7 server. Ubuntu 16.04.5 was 580GB thick provisioned taking up a lot of space. Backed it all up. It will go away and be recreated as a Ubuntu thin provisioned Word Press server with the latest PHP, MySQL and WordPress on it. I will get another SSL cert for it.
I see I can get plugins for Wordpress that migrate sites to other servers. Yes, they work. Even the pro ones are not expensive.
My VMWare 6 U3 server can create virtual hard drives. How about 4 separate hard drives installed as thin provisioned drives.
1.) /boot 30 GB, probably overkill but I don't always cleanup the old stuff.
2.) / 50GB, My CentOS 7 server with all the LAMP components uses 4.7 GB.
3.) swap of 10 GB. I will give it 6GB of RAM. I doubt I will ever need a swap partition but 10GB isn't that much space to worry about
4.) /var of 500GB. I other CentOS 7 Wordpress server has my 4 websites on it. 308GB out of 500GB. I can create another website and split off my parents and siblings stuff from my wife and children.
What do you think? I can expand each drive as needed. Thin provisioning doesn't use the space like thick. I have never done multiple hard drives in Linux installs. I will go back to my old RAID method of installing separate RAID volumes for each partition. I don't need to screw around trying to move stuff off CentOS 7 to expand a single drive install. I have room to do this 4 drive setup in VMWare.
