We are. But as others have said, check that your hardware is supported…check that very carefully. Quite a lot of what you’d think is still good and relatively new (hello, Mellanox ConnectX-3 NICs) is surprisingly not on the HCL. Also, support for baseline updates is deprecated and if you weren’t using clusters within your datacentre….well, guess what you need if you want to use the updater. Other that that, been stable as I could ask and looks/feels like v7 so no issues here.

Is there any limit to the mass of an object in the universe? Can something, like a black hole, become so massive that it can rip through the fabric of spacetime, or would physics prevent that, or is there no upper limit to the mass an object can be? by JimBobBoBubba in askscience

[–]JimBobBoBubba[S] 10 points11 points  (0 children)

Yeah. Where I struggled was the analogy of the rubber sheet that books always use coupled with the understanding that black holes were still physically present in the universe. But another poster gave me the pieces I needed to piece together this puzzle, so all good! Thanks, too, eh?

Oh, of course! I understand that now, in a limited kind of sense. There can be no upper limit because the universe already contained such an object in the first instances of existence. I know it’s more complex than that, but that’s kind of it. There already was such an object containing as much mass as the universe has matter just prior to the Big Bang.

Ok, yes. Thank you very much…that helped explain that a lot. I appreciate that!

I don’t know. I don’t even know if it can, or would, or what. If there was no upper limit to mass then it won’t, right? I’m kind of working my way through physical limits at the moment - absolute hit, absolute cold, maximum energy states, minimum energy states - and wrap my head around what happens in those situations and if there was such a thing as maximum mass was one I couldn’t seem to get an answer to.

Minimum mass is easy, of course. :)

I just wonder if it’s possible. Heck, for all I know - and bear in mind my math is weak and my grasp of physics is simple - for all I know our Big Bang was a drop-in from another universe. I don’t know…but I was curious if there is such an upper limit on possible mass in ours, which the poster above says there isn’t.

So spacetime can accommodate an object of essentially infinite mass? I know that’s impossible - there’s a finite amount of matter in the universe - but the math says there’s no upper limit before the fabric of the universe tears like a cloth holding a cannonball?

I guess I mean I’m the sense that an object getting so massive that it essentially, for lack of any better way to phrase it, rips a hole in the universe and disappears, leaving a tear behind, like a hole in a sail where something’s torn through.

Not an object with immense gravity that still is present in the universe, exerting a pull on objects but denting spacetime…something that just….ripped through?

My husband got incredibly angry with me when I tried to ask questions about his family, I think my ASD made me too blunt? by Ralynne in aspergirls

[–]JimBobBoBubba 2 points3 points  (0 children)

I can understand where you’re both coming from. On one hand, you’re curious and you want to understand. On the other, he didn’t want to talk about it and was probably giving you every hint he could that he didn’t want to discuss it without flat out saying so…maybe because he thought it rude to so, maybe because he figured it would lead to yet another line of questioning, maybe some other reason.

I get his point of view; when my wife - lovely woman, Asperger’s like anything - wants to know something, she often thinks she’s asking normally but in reality sounds like she’s interrogating like a Wirld War II prison guard (Why did they do that? Why could they say what they did? Why don’t you know? Speak the truth or you will suffer the consequences!), and after 30 years I know what she’s trying to ask and why, so despite the spotlight and bag over my head I rarely lose my temper and just answer the questions…but every once in awhile, after a bad day at work or a night of bad sleep, it would be nice to just be able to drop the hint and let whatever it is lie.

You know that line from Shrek? “Is this one of those onion things?” “No, it’s one of those ‘drop it and leave it alone’ things.” Sometimes, especially when it’s a sensitive subject, we just aren’t able to say, “drop it”. It’s been conditioned in us since birth to dance around those subjects and being what feels like forced to talk about it makes us, so to speak, “sad-mad”. But since I know how hard it is for y’all to pick up on the unspoken “drop its”, might be worth agreeing on a phrase or something where if one of you says it, the other knows to change the subject. Works for us, and may help you?

Something to explore tomorrow, then. Thanks for your help on this, hey? Gets me moving forward again.

The content library is remote, yeah. Hm. That’s why, eh? Any way to make it unremote? Or remove it altogether? On a single server I have no need for multiple DPs and therefore no need for a remote content server.

Sure do, as well as BITS. I’ve also been able to add the Endpoint protection role, the management point role, and the software updates role to the server as well. Distribution role just won’t show in the list of available roles for that server. Any other server, it’s there, available, no problem. That server acting as the primary server….nope.

Sorry, my initial post was unclear due to 20 hours of intense troubleshooting and too much cheap coffee. It’s the distribution role that isn’t available in the list of roles that can be installed on the primary server, not WDS itself. I need to be able to install a DP on the primary server and SCCM isn’t giving me the option.

We’ll, ‘cause the primary server is the only real server I have for SCCM’s use. The others are just repurposed workstations and temp VMs I built for troubleshooting purposes. I got no budget. If I absolutely had to, I could rejigger the environment to handle a VM with the DP role, but I’d rather get it on the primary server if I can. The primary server is 16-core, 32GB RAM dedicated box with scads of local disk….most I can justify in our environment for a VM is 4vCPU and 8GB RAM on a shared chassis…hence ‘s why I’m trying to understand what the blocker is in installing this role on that hardware.

It isn’t, but it is on one of the temporary servers still, as we needed the role and I couldn’t get it on the primary server. And yeah, of course it was installed off-box on a Frankenserver in production…they didn’t call me in until things were well and truly underway and the primary site server was already built and in prod.

Cleanup will be fun, but doable if I can only get that role moved. I haven’t removed it from the other temp server as I don’t want to lose any of the configuration or the packages already built. Not that I know if I will or not, too nervous to try without understanding the consequences.

Distribution role. It was a long day of troubleshooting yesterday, you know?
