@johnhooks The difference is 6 compared to a half dozen (at least in this case.)

I used to know a reason why you would use less or more in certain cases, but it's been so long that I no longer remember what caused a difference.

I know of no case where you use more. I always used it because I learned it first, but less is the only one you would actually want to use.

That's a good question... when does chrooting make more sense than containers today?

Storage is one. Lots of people use chroot jails for storage purposes. Containers are heavier than chrooting which has effectively no impact on any resources.

Looks like there is quite a bit included in the free version for up to 10 premium users, and 10 basic users. Interesting.

Yes, it is quite extensive.

Thought I'd take a quick look at this. I like how the output looks, but agree that I wouldn't want to leave it running. The loadavg jumped just from starting to look at the output.

it would have to, that is a LOT of output!

Wow, you're not kidding about that. Even gives you the current available entropy from /proc/sys/kernel/random/entropy_avail. I've never seen something give you this much information and be so easy to get running.

As of CentOS 7, DNF isn't even an option. Yum is the only thing to use.

Correct. But it has been in fedora for a while now.

Is dnf the default in Fedora now?

Yes

@scottalanmiller Thanks for this post and answering all my questions. @travisdh1 Thanks for answering all my questions as well. Good Thread!

Scott, you mentioned that this is all at the kernel level - could you roll your own version of this?

Sure, you'd have to write your own storage layer, though. So it's not trivial in any way.

OH.. that's where I was confused I guess... I thought the storage layer was part of KVM (that's the hypervisor they use, right?)

Not part of KVM itself. The Scale HC3 is unique, there is no software version available on the market.

So they wrote the storage layer? Cool - good to know/understand that.

Yes, Scale is primarily a storage vendor. Before they made their Hyperconverged product, they made scale out storage only. That was before KVM was mature enough to make the HC3 product. They no longer sell the storage layer, it is now developed purely and designed solely around the needs of the HC3 product so is completely unique to that. It's the storage layer and the storage integration (and support) that are their selling points. That's what makes them special and unique. KVM and the hardware on its own you could do yourself and you could easily make due with a different interface.

We need some latency numbers from around the world. Anyone want to collect some for us?

Here is the first IP address. A long running ping (hundreds or thousands of pings) would be good, we need the final stats from that:

104.236.119.59 108.61.151.173 172.99.75.133

We have a good idea on bandwidth, IO, CPU and memory. Network latency is pretty huge.

As a matter of correctness... Do you have EPEL /REMI or any other repos installed in your CentOS 7 image?

The script is connecting the Gitlab RPM, that is all. The base image he uses for all of these is CentOS 7 minimal, release 1511 unless he has changed the base template on his scale cluster.

Right. I'm just curious if he has added the epel-release or any other repos to it.

Definitely no EPEL. I often use it, but avoid it in the base image.

@scottalanmiller said:

Just tested and working great for me.

It makes the warning go away. No clue if it helps performance any.

If you want to enable PHP 7 you need to edit a different repo file to find the remi-php70 repo to enable.

nano /etc/yum.repos.d/remi-php70.repo

Are you using an extra app that is not part of ownCloud itself? What is the exact app?

no, users access OC using a browser

I don't mean an app for the users. i mean an app installed on ownCloud to provide the encryption.

0_1457640037846_Capture.PNG

Could that encryption application be what is blocking the file sharing?

maybe, but it wont let me disable it

That's not good. Perhaps because the content is already encrypted?

i disabled the module in the apps menu

I have to look up SSL certification on CentOS 7 now. I've only ever done it on our Barracuda SSL VPN which was just an upload. Here we go

I think you need to look up SSL for Apache if you are trying to encrypt ownCloud. I think someone has a guide on here somewhere about it.

I think @JaredBusch has it in his 8.2 guide. I think he did self signed though. I'm unsure of how to do this on linux with digicert or something similar

It was a self signed for the example. but I use letsencrypt myself. Some clients using ownCloud have StartSSL certs.

I just used this myself to make a new block device in a single line. Awesome 🙂

While I have never made a how to with a port range, the basic firewalld syntax is used all over the place on this forum by me and every system that I have ever seen that accepts a port range does so with the range hyphenated from lower boundary to upper boundary.

I would have thought that this was a colon, though, not a hyphen.

I have never seen it commonly used with a colon to represent a range

Native IPTables. 🙂

I rarely work with native IPTables. That would explain a difference in point of view.

Yeah, and for me I pretty much have done raw edits on /etc/sysconfig/iptables and never used external tools. Now with FirewallD I'm relearning the syntax for everything on Linux firewalls.

Well, at least I'm not the only one then. Learning how to use firewall-cmd still feels a bit odd.

In case anyone else runs across this same issue, I got this resolved with a simple command:

dracut --regenerate-all -f && grub2-mkconfig -o /boot/grub2/grub.cfg

After doing this, everything booted up properly.

I then installed hyperv-daemons, rebooted, and everything works great.

@scottalanmiller Didn't Red Hat take Centos back in house?

That's a weird way to say it. "Back" would imply that they used to be in house. CentOS was a third party and Red Hat bought them.

At the moment I can access the NFS Share using WinSCP, and copy from the NFS Share to my windows PC without issue, but I don't believe I can schedule this.

With PuTTY you can.

Care to elaborate?

PuTTY comes with a command line SCP client.

I never noticed / knew that!

Took me like a decade or so before someone pointed it out to me recently too 🙂

it's robocopy all over again 😛
