@JaredBusch I had Windstream do this to me once. Such a stupid move on their part.

RE: What Are You Doing Right Now
Windows: "No, I will not allow you to delete these partitions because reason xyz!."
Me: "Oh really? Breaking out the big guns."
Me: (inserts ultimate boot CD USB stick with linux partition tools)
Linux: "oh you want to delete these partitions?
RE: DuoLingo Challenge
@scottalanmiller How are you liking Mango Languages? I started it and it is different from DuoLingo, but I like it. It provides variety.
I like it a lot. Totally different system. I use Drops, too.
Agreed. I use the same. I'm also looking for another way to talk with other natives. I have used Tandem before but it is only for iOS or Android. I wish they had a web app.
RE: Reconsidering ProxMox
following this thread. Time to test this out on a spare box. I've always steered clear of this due to the feedback on here, but initial research looks like it has some pretty awesome features. The builtin backup features are nice too. And it has an API for even more automation. I like that. Time to spin up a box.
RE: Greenfield HA environment choices
@fuznutz04 so what I'm thinking that I am hearing is, and correct me if I am wrong...
- You perceive platform updates as carrying risk and headache.
- You want to do platform updates at the riskiest times (prime production) rather than waiting on a greenzone. I assume because you work during prime production and sleep during what would be the greenzone.
- You run fragile applications that we generally would not consider production ready and don't care about uptime protection on them in general (but don't want unnecessary downtime, either.)
This is what I think that I am hearing, both in your descriptions of why you want this feature, as well as your perception that the other company's non-HA solution was "great". You are looking at it as a feature to make IT management easier, so the application availability isn't the factor of concern here.
To that I would say that...
- Platform updates on systems like KVM are trivially easy, insanely fast, and not a problem at all. You probably only see this as a concern at all because you were running Hyper-V (or VMware) where system updates are problematic. KVM and Xen aren't like this. So if you use them, I think your entire premise for this evaporates.
- I would simply not do this. Even if I have HA, I wouldn't do it because prime production time is never the time to test your failover systems. Everything fails and HA is a highly risky operation even under ideal conditions and there is no vendor that is completely reliable. Doing off hours maintenance isn't just trivially easy, but it is easily scripted during production hours. Why take on cost and risk that is unnecessary? Just do an update and reboot off hours.
- This is real and we can't easily work around it. But the decision that these would require off hours support for safety was made at the time of acquisition.
Also, the cost to have an MSP do this for you, if you didn't want to do it, would be far cheaper than the cost of HA. And fix the problems way more thoroughly because it would address everything, not just one piece.
All good points here.
- Platform updates being risky - I agree with that piece for Windows. We've all been in situations before where a simple update takes forever, and there is not progress on Windows. In all my cases with Windows, it always comes back, but compared to a KVM host update, it can sometimes be a night and day different.
- Updating during normal business hours - I must have misspoke here. I never do this. I always do update after hours as much as possible.
- Fragile applications - Yep, this is true in some cases. It's not what you want as the person supporting the ops piece of the puzzle, but sometimes that's what you are working with at the moment.
Taking time to think about this more, the real want for HA stems from fear of the unknown and time to resolution in case of disaster. Example:
I do an update to the host and it bombs for reason X. How fast can I get my backups restored on another host?
A host crashes - Same question. How fast can I restore to another host?
My team is small, can anyone restore properly in a timely fashion?
Would a simple failover system (let's not call it HA, just an automatic failover to another host) be a good solution to be able to keep the VMs running until the failed host is fixed?
All of the points brought up by you and others definitely make me pause and take a step back and really think about what the source of this post really stems from. So thanks for that. Time to think on this a bit more.
(also, now following the Proxmox thread as well )
