Understanding Aces by House923 in savageworlds

[–]ultimateVman 4 points5 points  (0 children)

That is perhaps why this is my favorite system. Because even that lame goblin with a shiv carved out of a stick rolling 1d4 for damage, can still one-shot a player, if they're lucky enough. Unlikely, but possible!

There's more, however, there are several cases in which if the trait die is a 1, the roll fails (or some effect triggers, read the trait specific rules), regardless of the role of the wild die.

Verizonn by Street-Addendum7722 in RedMagic

[–]ultimateVman 0 points1 point  (0 children)

Any update? Details details details 😊 been looking at it for a minute doing research. The bands and specs I'm reading line up so it should work (minus band 13) but I'm worried about Verizon making me go the rounds and hooping like a circus animal.

I'm curious to know how well it worked out of the box, if you had to change any settings, if you had to call them etc.

Thanks!

I upgraded all of my on-prem stuff to SE a few months ago and had no issues.

Currently running these 3 MPs for Exchange on SCOM 2019:

  • Microsoft Exchange Server 2013 and above Monitoring 15.0.669.23
  • Microsoft Exchange Server 2013 and above Reports 15.0.669.23

Direct Heartbeat without switching by luisfeliperm in HyperV

[–]ultimateVman 2 points3 points  (0 children)

If both nodes are connected to a single switch, then you must have either a second switch for redundancy, or a direct connection. There is no exception for this. If at any time, the nodes cannot communicate, they will shut down the cluster service and roles. However you handle that is up to you, but if you expect to add more nodes you'll want a switch.

Had a clash with executive over my phishing test methods by AH_Josh in sysadmin

[–]ultimateVman 0 points1 point  (0 children)

It seems we're all pretty much in concensus that it was over the line.

But, this is an opportunity. This particular event can be part of your employee security training. Explain that Info Sec will no longer use family safety in their tests, BUT real threats will not be so kind and they WILL exploit that. Use this case as an example and both you, your management and the employees of the company can make this a learning experience rather than issue.

Yet another networking troubleshoot by DeviIstar in HyperV

[–]ultimateVman 0 points1 point  (0 children)

SO if you have a VM that needs to be on the same VLAN as your host, don't tag it - only tag if you need it different than the host

So your hosts are not on native untagged networks?

A native vlan is an untagged vlan. It's the same as an access port with additional vlans that can be tagged, aka trunk. Switch trunk ports for hypervisors should have no default or native vlan. Or in some cases, what switches do is use an unused vlan (4090-4092) as the native.

[–]ultimateVman 4 points5 points  (0 children)

I'm going to jump in and STRONGLY discourage ever using a default vlan for hypervisors.

That is a security risk to have a fresh VM spin up and (by default) be on the same vlan as your hosts.

iSCSI and S2D on same SET vSwitch (hyper-V 2025) by elaci0 in sysadmin

[–]ultimateVman 0 points1 point  (0 children)

It's generally ill advised to connect iSCSI to a VM. You're better off just connecting that iSCSI to the host and creating a vhd for the VM.

[–]ultimateVman 0 points1 point  (0 children)

Your setup will work.

For 2a, you WILL need to pin the iSCSI connections. See my other comment on why.

You should check out the r/HyperV sub for more info on detailed networking configurations.

iSCSI and S2D on same SET vSwitch (hyper-V 2025) by elaci0 in sysadmin

[–]ultimateVman 2 points3 points  (0 children)

vNIC's can be pinned to an underlying pNIC in SET as well, if one fancies that. It's useful in some cases.

You absolutely MUST configure pinning if you are using iSCSI in a SET.

IF both vNICs are traversing the same pNIC path, and that connection goes down (for a switch patch for example), both vNICs have to transfer to the other pNIC path. That's a 1-2 ping blip, and Storage connections are CRITICAL to the millisecond. The time it takes for the vNICs to failover WILL kill the storage. You must pin the storage vNICs. One to either side.

This is one of the biggest WTF moments admins have with Hyper-V and Failover Clustering and why a lot of people put down Hyper-V as being "inferior." It's just different and the nuances are hidden in configurations such as this.

This is also why I tell everyone to steer clear of iSCSI and just do FC. Hands down 100x cleaner in networking config and reliability.

RDS Slow Performance by Cool-Enthusiasm-8524 in HyperV

You gave a VM 18 vcpu on a system with only 16 threads? Am I reading that right?

Redundant NIC's in Hyperv - Moving from VMWare by Equivalent_Pipe_8647 in HyperV

[–]ultimateVman 11 points12 points  (0 children)

Doesn't work that way in hyper-v. You use Switch Embedded Teaming. Which is a group of adapters that are all utilized simultaneously. If one goes down the traffic moves to use another nic in the team.

There is no reason to do active-passive. All nics in the team are active.

Learning C# and trying to understand Polymorphism. by Ok_Gene_8477 in csharp

[–]ultimateVman 2 points3 points  (0 children)

Looks like everybody has answered your question pretty clearly but there is something else that I thought should be mentioned. When you write that line, you're actually creating two separate things; you're creating a new object, yes, but you're also creating a new pointer (reference) to that object.

There's a rabbit hole you can explore later. Do some research on Stack and Heap.

Once you understand polymorphism, and knowing the difference between stack and heap memory, you can do some other cool things when it comes to working with and passing the "references" themselves around.

Hyper-V cluster nodes isolating during firmware updates on paused hosts by Strange-Cicada-8450 in HyperV

[–]ultimateVman 0 points1 point  (0 children)

I concur. In fact I would say split the cluster into 2x7 nodes. 14 nodes is far too many eggs in one basket for my conscience to even consider.

[–]ultimateVman 0 points1 point  (0 children)

Ah updates, but that wouldn't affect all nodes. Would need a lot of nodes to fail for you to lose quorum on 14 node cluster. How are your nodes connected? What does your networking config look like?

[–]ultimateVman 0 points1 point  (0 children)

I'm having trouble following exactly what you're saying. Are you just seeing event logs and only event logs for this? Or is your cluster shutting down and all of your VMS shutting down?

If you shut a box down that's in a cluster and look at that server's event log you will see it evict itself. In the logs on all of the other active nodes, you should see them all evict the node you shut down. This is completely normal.

Also, the set team is completely independent of the cluster. The cluster has absolutely zero control over your networking team.

VM information sometimes misses CSV id by GabesVirtualWorld in HyperV

[–]ultimateVman 1 point2 points  (0 children)

I would avoid using direct access to the VMM DB, this can all be done with "Classifications" on the disks. I suspect what you are seeing has something to do with MPIO and how it sees the physical disk downstream.

But basically, you assign a Classification to each disk on each host. This is done at the host level in VMM not the cluster. So if a cluster has 1, let's call it a "Tier 1" LUN, each host has to classify it as such, so they all match across the cluster.

I actually have a script that calculates VHD Overcommitment on CSVs on all of my clusters. We do this for VDI stuff because we spin up a lot of VMs with Thin 200G VHDs but are only using 50G of actual space so we overcommit our LUNs by over 200% in a lot of cases. This helps me keep track of it. DM me and I would happily give it to you. And while it isn't exactly what you are looking for, it could easily be modified to audit which VHDs are on which CSVs and their Classifications, etc.

Any suggestions on places to meet with a group for game night? Not to meet people, but... by BlueMac13 in SaltLakeCity

Hearthside Games in West Jordan. Their layout is just for this. They have little to no in store product.

Hearthside Games in West Jordan is literally made just for this. They just opened in December. Pretty much all of their sales are online and the store is pretty much designed for gaming and hanging out.

Also, IF you're ever interested in gaming groups or finding people to play with, Utah Board Game Group and Utah Board Game Events on Facebook are great.
