Still preferred fallocate instead of dd to create a swap file?

dd if=/dev/zero of=/swapfile count=4096 bs=1MiB && chmod 600 /swapfile && mkswap /swapfile && swapon /swapfile && echo "/swapfile swap swap defaults 0 0">>/etc/fstab

Still using swap file? Memory is cheap. I don't recall a server where I created swap partition or swap file.

Memory is NOT cheap, not at all.

It is if you own it. If you rent your hardware, yeah, it adds up.

Even if I own it, throwing away 2-3GB of RAM makes no sense. Now, if I own it, I can easily assign 4GB of RAM then remove it once installed, by why? That's harder to script and still no benefit.

It's a bad habit to see resources as cheap and so waste them just because you can. Extra memory doesn't improve performance, it hurts it (just the tiniest bit). And it's not free, if you always apply twice as much RAM as you use (or four times, here), that gets costly one way or another. Either you wasted money overspeccing in the beginning, or you are stuck buying more now.

Can you reassign disks between VMs yet?

The hot add disks was a huge pain before. I couldn't believe I wasn't able to do that.

@scottalanmiller said in New Infrastructure to Replace Scale Cluster:

So if a VM dies, oVirt will provide non-FT failover, yes. And by having failover you might achieve HA. And oVirt is a critical part of making that possible. But it itself isn't HA, nor does it guarantee HA. It's just a failover component that you can use to "do" HA.

It's a component you buy (well, this one is opensource, but still), part of a solution that would cover other potential failure points. The solution in general is also something you can buy, in order to achieve a certain level of HA for those VMs

Way to go guys!

I have Ubuntu 18.04 and Deepin and it works great although Deeping uses a different UI.

What desktop environment are you using on ubuntu?

Gnome

I’ve got 18.04 with KDE.

Have you tried ubuntu Budgie 18.04?

No. I only have the one 18.04 instance.

Ubuntu Budgie 18.04 looks pretty nice.

That's a great looking desktop.

Doesn't look bad. What kind of RAM utilization does it have?

You actually get your SMB clients to plan ahead? /gasp!

We try!
