And a follow-up here: I received my low-end server (Dell T30) last night, and I've finally got it configured and testing. I think you need to reinstall and choose a better disk layout. I installed and told Proxmox to configure my 2 drives as a ZFS mirror, did some testing, and added a Samsung...

I'm not familiar with Macrium. The system I'm referring to runs a on the VM itself and requires a dedicated backup computer to initiate the backups according to the schedule you set, then store them. In my case I've got one backup server in the data center, and another here (actually, this...

I'm doing a build on a Dell T30 - I know it's low end, but there are reasons (like trying to get the entire cluster to run on a 15amp circuit, and only needing 2 machines to migrate my VMs to the new location so I can bring datacenter boxes home and re-purpose them...) My goal was to put a...

Well, let's think it through using normal RAID levels and keeping ZFS out of it. Let's say you're writing a 100 megabyte file: With RAID1 each device is writing the whole file, so you'll have 100MB written per device. With RAID0 each device gets ~ half of the file because it's striped, so in...

I've been using R1Soft Servernbackup solution for a few years. It works well, but I'm not sure what the current pricing looks like - they were bought, now I think they've been spun off again. https://www.r1soft.com/product-features Basically, their backup agent runs inside your VM, and it...

You know what? Never mind. I figured it out. :) This is the advantage of buying a $31 Kindle Technical Book, kids: they contain useful information if you're wise enough to keep reading before asking questions of others on public forums. :p

Thanks, ti. Once I have shut down the datacenter I've got a bunch of boxes I can add to the cluster instead - supermicros with dual E5 CPUs and 128-144GB RAM, though they all run hardware RAID. I can migrate that to the home office as well and maybe save some money, but if the T30's are enough...

I read somewhere that you can dynamically increase resources, but decreasing them would require a reboot.

It's been a while since I looked into ZFS and I'm inexperienced, but here's what jumps out at me: Performance on ZFS is driven by caching. There's the ARC which is system RAM devoted to caching recently used data so access is nearly instantaneous. There's L2ARC, which is used for...

My Situation: I've got 3 Xenserver hosts in a datacenter that's overkill for my needs, and I'm tired of paying for a full rack. So I'm going to host out of my house - gigabit fiber and generator backup are already here, so it just makes sense. It'll be a step down as far as uptime, but for the...

Nicko, I'm new here but I'm going to try and help out. You're seeing really slow disk performance with the mirror you've set up. If you change that to a stripe then you'll get maybe double the performance, but the new number will still suck, plus you'll be something like 4x more likely to...

Actually, I bought Mastering Proxmox last night on Kindle, so I'll take this down, find what answers I can, and come back with more later. :)
