Lol I didn't even know indeed had a dark mode page plus.

I think it does but being specifically titled 'system administrator' is getting smaller to me. It's moving more into specialized roles I feel as opposed to generalists but I think there will probably always be places that are looking for a system administrator.

Thank you for the share and your answer 🤝

Yeah we already had a call to start the migration process for our veeam licensing to move to VUL so we can just backup any type

Let me know what type of configuration and I'll try as well to see if I get similar results.

@@sysadminsean the main difference is the one that fails, is using an IDE type HD (attached to the VirtIO SCSI controller) and the one that succeeds uses a SCSI HD attached to the same controller. I'll make a second similar image of the failing system to see if that is indeed the issue, or it's coincidence.

@@bradgrandorff1058 I'll see if I can create something similar. We're still testing new proxmox backups and doing file level restores, and full restores but we won't have too many different types of controllers when we're done.

@@sysadminsean doesn't appear to be that, or at least, jst the controller. I backed up a running installation of windows (too lazy to do complete install) and with it in a running state it did back up fine with that controller combination. For the record, I would never use the IDE in reality, it's just that when I first installed the image, windows has a brilliant error "Windows can't install on that drive 0x80300001" when using the VirtIO drivers. It simply means to mount that Windows install ISO. Long story short, first time through that I just used the IDE driver, thus the reason I have it as an image.

I honestly think it's doing basically the same thing. But veeam allows us to send our backups to immutable cloud storage, and lets us utilize multiple different hypervisors if we so choose, and that's kind of big for us. If you are only needing to backup proxmox lxc's and vms then PBS is a perfectly fine way to go, that product is pretty nice.

In addition Veeam runs on WIndows "Veeam needs a Windows box but the database can be Postgresql so no need for MSSQL." Nothing wrong with that, just, mentioning the difference.

I'm really impressed with the implementation so far.

Sure! Just remember one machine needs to be the provisioning host/head node and others are compute

I do it's really not very expensive and a well developed tool I think. I've migrated a bit from it recently though as I move away from Windows more but it's still good. I'd suggest trying out this, mremoteng, and royalts, and see which one fits your needs most. For me it was MobaXTerm for years

If they can talk to each other it doesn't matter what their ip is but if they are geographically distant I wouldn't go with ceph the speeds would be too inconsistent.

@@sysadminsean they can talk to each other but the ceph monitors are not getting setup correctly

When you say three different public ips do you mean different public subsets? If so it just won't work properly with all the extra networking. Ceph really should only be used on an isolated 10gb or better network. I use it on 1gb but all on the same network switch and not for any production loads so I'm not too worried. I also would highly caution giving your hypervisor a public ip just for the sake of security.

@@sysadminsean well that public ip assigned for hypervisor is islated as they are nin diffrent regieons

@@mohammedfaisal6946 Thats not exactly what I mean. Your hypervisors should not have their management interfaces attached to public facing ips, they should have private networks that you would access via a VPN or other secure gateway access. If each proxmox host is in a different region CEPH is not going to function properly at all due to all the different networking and routing you will be dealing with. They need to all exist in their own network usually all attached to the same network switch or switches depending on how you do your config.

Considering how many placed were down all day. I'd say that's probably exactly what happened for many.

This was applied through crowdstrikes software if you are a customer. Their product is like a defender style tool to protect from exploits, threats, intrusion attempts etc.

What errors are you getting? Did you install the qemu tools? Are you running bitlocker, tpm, etc. ? I don't do much with desktop OSes these days but I can try to help

@@sysadminsean Hi, it work with BIOS(SeaBIOS). Many thanks

Yeah this was confusing on my machine it would be ens19 the 10.0.0.1 ip address. This is the flat network that talks between the headnode and the compute nodes.

Check the following stuff 1.) firewall on and ports open (80 for http, how pxe offers up the image) 2.) verify that httpd, and tftpd service is running 3.) verify that dhcpd.conf has the info for ipxe to tell the nodes where to go for their images.

this is pretty much just the surface of it all. It can get even wilder. So you can take software like spack, and let people deploy singularity for their jobs to basically run containers inside nodes so that its like nodes inside nodes to do even more complex jobs and job arrays, and even more stuff that we don't even begin to touch where I work because it's not really a focal point. Now I don't cover it in this series (cause I can't afford to have any) but you can do GPU based HPC or gpu pinned based HPC as well for doing al the AI, LLM, and even bigger computations.

@@sysadminsean Sounds like I need a bigger team. :)

So for me coding wasn't required but I started a very long time ago. If I was starting over now I'd want to know powershell, ansible, terraform, bash, and any other scripting language better than I do now only because tons of what I do these days benefits so greatly from it. I should probably do some code livestreams to give me more reason to practice hah

Thats why there's another video though some folks do have trouble with that esxi importer so they can at least attempt this method as well.

Sure thing I'll actually be going over a lot of this in the next video mainly because I really don't like openhpc's step of disabling the firewall so we'll discuss that and I'll show you everywhere you need to change ip's on the system and dig into the bones a bit more.

Thankyou ​@@sysadminsean👍

I got a few more vids to release but the docs are good

Gotta have a on call rotation if you absolutely have to have on call and your boss needs to enforce how the team does it otherwise the good folks just quit.

@@sysadminsean Gotta admit, I am looking elsewhere. The IT market is dead in this area though unless you want entry-level call center/help desk roles or are very experienced and can be a sysadmin (but at below-market pay). Thinking about getting out of this all together. I loved help desk at my current company, made above average pay, but it feels like the people at the top just want me out despite all the positive feedback and stellar reviews I got from my supervisor in that department. I think being a network engineer just doesn't suit me. I tried to apply to data center operations and had the requisite skills but they hired outside instead (when there were only two applicants).

By the way, could you make a final test in the final video with running an NWChem job on the nodes?

I could try, do you know of any test jobs I could run and expected result times? I promise my 'cluster' will be very subpar but I could absolutely show it 'working'

@@sysadminsean There must be many testjobs in the NWChem folders. Job time is not important but how i can get to the point where i can run jobs across nodes XD The machine comes next week. Initially i am thinking of making a simple LAN and the four machines will be individual units. Three will work with the best installation we can do currently and one will left for installation and HPC creation trials. It is really appreciated if you alter your plans by my request ;)

@@szbalogh I'll do what I can but can't make any promises.

Honestly I can't sat that I've even looked into anything like that. I'd have to do some research as I'm still fairly new to the ins and out of ceph
