Well, at some point in mostly recent memory you were all about CentOS, CentOS, CentOS, all about CentOS.
Then at some point you changed to Fedora.
This is the thing I have a hard time wrapping my head around.
Like how we can tell someone that OptionA is the only option out there, and you'd be a moron to go with another option. Then people get behind OptionA, and implement OptionA. Then one day later, it's like yeah only morons use OptionA. OptionB is where it is at.
When can you ever really trust any of the options?
The way I see it is that Fedora is my go to unless some weird applications requires CentOS.
You can only go so long relying on EPEL to fulfill the need that Fedora can provide natively.
Same here. CentOS is fine, but I'm not going to choose it. Some things, like Zimbra, demand it, so I use it there. But when I have the choice, I'm on Fedora.
Have you ever install Zabbix successful on Fedora? It works flawlessly on CentOS.

I haven't done a recent Zabbix install, cannot say.

Scott with consideration for the total amount of ram, cache, cpu power etc, why is the world still stuck on "hardware raid" ?!?! Seems to me like it needs to die lol.

Because it solves a few important problems:
- It is large profits based off of people not understanding RAID systems. So it's not going anywhere for business reasons.
- It enables simple separation of duty between IT and bench staff. No IT needed for disk replacements.
- It allows systems like VMware ESXi, Citrix XenServer that lack software RAID and systems like Hyper-V that have no good software RAID to still work well.
- It allows simple cache mechanisms to be made available to staff that could not configure it safely in software.
- It allows for low cost work arounds to unreliable power systems.

Wish Google would fix this problem
but seriously, thanks for your help. I have clarity now on the matter. -

@scottalanmiller thats when i use the SATA spinning rust!!!! I almost cried!
Luckily the SSD got me better
Question should I use LVM or EXT ?

LVM and XFS most likely. The installers can be a little confusing if you don't know about how LVM works. https://mangolassi.it/topic/11302/travis-hershberger-linux-lvm-storage

@travisdh1 so XenServer will let me do that 3rd option?! Never heard of it and Iām about to google it.

Oh, XenServer? Yeah, you want EXT then. Only option that allows thing provisioning in XenServer, also one of the reasons XS has fallen out of favor around here.

Ok gonna nuke it and redo it as EXT
-
Hell im anxious to see how fast my work cluster is cause this is crazy at home
-
So when I first install XenServer and I "tick" thin provisioning, behind the scene it's making the drive ext, so I assume if I didn't choose thin provisioning it would have made it LVM?
