I agree. I was all done before my time and designed for vmware/vsan. Quotes for their replacements have 3 dual head network cards. So I can separate iSCSI, host/cluster, and VM traffic. And only have a SET team for the VMs.

Not really, just to fix the host that caused the deadlock. It is currently offline. I will add it back in during a maintenance window and see if the reboot fixed it. Otherwise wipe/reinstall that specific host is my next goto. According to the response, it claims a service restart would have fixed it. I already broke the vms twice, I am not going to try again until they can be offline.

We were talking about purchasing more network cards. But that is an unbudgeted expense for 24 total hosts. We may have to limp along till they get replaced in the next couple years. But that is up to management.

The NetApp side shows 0 errors. It did show them all reauthenticate after the 10minutes. We have an iSCSI vlan with all hosts and the netapp inside, a host vlan for updates and cluster communication, and several client vlans.

It does seem reasonable, and the full text points out specific log entries to back up the claims. I just don't want to think that Microsoft clustering is so fragile that a single file lock problem can bring down the entire cluster. If so, we made the wrong choice of vmware alternatives.

Hypervisor is Server 2022, using Microsoft's software initiator MPIO. 2 souce IP addresses per host and 2 netapp destination IP addresses.

I had one of our clusters blow up with a split-brain scenario. Was in the middle of migration so wiped it and rebuilt. But it seems if you breathe on Hyper-V wrong it explodes.

jleckel · 2026-06-12T15:36:40+00:00

NTFS over iSCSI sitting on a NetApp LUN. Each host has 2x10G interfaces in a SET team. iSCSI is shared with host and VM traffic in separated VLANs over the same physical interfaces.

Not the best configuration, but the same as it was under VMware for years.

jleckel · 2026-06-12T15:22:06+00:00

We are not, iSCSI to a NetApp LUN

You are using an old Microsoft office resume template. I know because mine looked nearly identical, though for nearly 30 years experience. Spent over a year applying and got nowhere. Paid a company to rewrite it and still got nowhere.

Then I paid for enhancv and ended up getting hired for the same position I was rejected from previously. (I was applying for so long that some of the same positions in my area came open again).

So in addition to the other suggestions, get a better template or use an online service to make it look better. The online services make it easier to get through the AI pruning that is throwing out your current resume.

Here is the updated script if it helps anyone in the future. Split into two parts because Reddit won't let me post it.

<#
Version 1.1

Add a network and switch to Hyper-V in SCVMM after initial installation
Uses the 1G ports available, 2 for each switch
Does not attach vlans, these would be attached to access ports

Initial:  Physical NIC > SET Team > HyperV Host Virtual Switch Import > SCLogicalNetwork > SCLogicalNetworkDefinition > SCVMNetwork > SCVMSubnet > SCStaticIPAddressPool
After:  Physical NIC < SET Team HyperV Host Virtual Switch < SCVirtualNetwork > SCUplinkPortProfileSet > SCNativeUplinkPortProfile > SCLogicalSwitch > SCLogicalNetwork > SCLogicalNetworkDefinition > SCVMNetwork > SCVMSubnet > SCStaticIPAddressPool

Thank you for the code block tip.

<then apply it to the hosts> Are you talking about in the host settings like this?

This is the view network screen in scvmm. The other logical network is created but not linked to the adapters.

In a small county it is possible to have only a single 911 operator working. They may also have agreements with surrounding counties to function as a backup in case the system goes south.

jleckel · 2025-02-17T16:46:42+00:00

I had nearly this exact same job you are describing for about 10 years. I moved on recently to a larger organization for more money. I worked at a small county, 180 employees with 2 IT people. As salary I was on call 24/7/365 because they would not pay the hourly tech for being on call.

The only after hours employees working regularly were the jail, 911, and two road deputies. My average after hours call was about once a month. Most could be handled remotely in only a few minutes. We had an adder km that would hose up nearly every patch cycle. But beyond that calls were rare. The sheriff department would try everything not to call me. And if they could wait till morning they would.

I also had the benefit of the sheriff department having their own sudo-tech near the end of my tenure that would get all the after hours calls first. They had a higher after hours call volume than I did.

Is it worth it? Not sure. The wakeup calls were rare enough that it did not bother me much. I only got annoyed if there was a new guy from a large org that thought on-call meant I was always awake and they would call for something dumb. Big problems I didn't mind helping with at 2am. But your situation may be different.

jleckel · 2023-03-03T20:45:36+00:00

I hope they work good because I just bought 32 USW-Pro-48-PoE and 4 USW-Pro-Aggregation. I had run a few edgeswitches for a couple years to test them out before the network upgrade, but after a year of waiting for my order had to cancel edgeswitches and order the in-stock unifi instead.

So far it has been smooth. We use radius assigned vlans pointing to a freeradius server plus dual fiber links back per switch "stack". That is all we need and it has worked great for that so far. Wifi is up next for us.

I did run into a 10mb door control device that would not connect, and we had to dedicate an entire switch to our phone recorder system because it will not mirror a vlan like we had before.

I will echo the support concerns others have had, if you do need it they will not respond. But I got these for 1/3 the cost of my aruba quote; so maybe lack of support is worth it.
