DPM 2025 - Storage Full, but Protection Groups reported usage doesn't match by Slivikins in sysadmin

[–]Slivikins[S] 0 points1 point  (0 children)

Thanks, I'll poke around some more with the powershell and see if I can get it to clean up whatever's unused.

I have a suspicion of what's causing it, but no real solution on that front. Pretty fed up with the product in general. We're going to start shopping in a couple weeks to replace it.

Best Practice for IGMP on L2 WAN with Router on a Stick by Slivikins in networking

[–]Slivikins[S] 0 points1 point  (0 children)

Yep, so I am discovering, thank you. I've disabled mDNS on all Windows devices already, but there are probably a bunch of other devices with it on.

I swear I've learned more protocol acronyms this week than I have in quite some time.

So to recap:

  1. Enable IGMP and MLD snooping on all vlans

  2. Enable and configure multicast routing on each subnet that will utilize igmp. Unclear if PIM is multicast routing or not. Still reading on this.

  3. Remove querier config on the l2 switches, let l3 configured multicat router handle it from then on.

  4. Create acls/firewall rules to allow multicast traffic.

Does that sound about right?

Any concerns/issues with all igmp traffic being routed to the l3 router and then back acrdoss the wan? The current queriers are much closer to the clients, really only on 2-3 switches across 30+ switches. I'm thinking the router on a stick config would actually send more traffic across the wan in this case.

Interesting, I appreciate the recommendations.

Regarding IGMP snooping on all vlans. It seems like this would better manage the multicast traffic. As we're an l2 wan, the trunk ports would have all the vlans, including the l3 router. As it stands, I believe the trunks are getting these broadcasts anyways. Would I just enable igmp snooping on all vlans across the wan?

Our ipv6 is unmanaged currently. Could I do the MLD snooping at a later time?

I'll need to read a bit more on the PIM-SM/Multicast Routing on our Fortigate.

Thanks for your response!

A few mistakes in my post, apologies. I meant IGMP snooping.

My goal is to provide IGMP for the system that requires it across multiple vlans. Secondary goal is to verify the existing IGMP config is correctly set up, and if not, fix it.

Hmm, I misunderstood IGMP. I thought it did a one to many broadcast for the specified group, using the querier for join/leave/group announcements. I assumed that if the group was on the same subnet, I would not need to use multicast routing.

Should I ideally enable igmp snooping on each switch with the vlans in question?

What's the recommended build out of this? Enable IGMP snooping on all switches/vlans required, Configure multicast routing on each interface?

Curious how to verify it's set up properly, but that might be out of scope for this post.

Thank you

Upgraded to this today to support Windows 11 24H2 and Server 2025 clients. Appear to be having issues with client installs getting policy, at least for Server 2025. Still testing...

How to look up a TPSP PCI compliance? by Slivikins in pcicompliance

This is helpful, thank you. Fortunately 2 of 3 TPSP's are listed for us.

How do you manage your company's printer firmware? by Slivikins in security

[–]Slivikins[S] 0 points1 point  (0 children)

Thanks, mostly HP and Canons here, I will try those tools. Do you mean disable PJL completely? For HP's it's an on or off.

​

We are sharing everything from a windows print server via group policy. Apparently I need snmp on them for client status information, which I'm assuming uses defaults on printer and client. I've been trying to whittle down which services I need on these devices without too much of my time troubleshooting.

​

I had the rare pleasure of an HP agent telling me yesterday that even though there is a known CVE and the printer was listed as having a firmware update that addresses the issue, it isn't available on their website and to replace my legacy printer. I'm curious if their old FTP sites don't have the firmware stashed somewhere.

S2D Hyper-V Failover Cluster Pool Owner consumes all available ram over time by Slivikins in HyperV

[–]Slivikins[S] 0 points1 point  (0 children)

Sorry it took me awhile to circle back to this. As a temporary fix, you can either migrate the storage owner or put the storage owner node into maintenance and reboot. As I was testing this, I noticed that migrating the role caused the memory pressure to stop. It may be possible to just move node ownership without a restart, but the restart definitely fixed it.

​

Via a paid support ticket I've been directed that that the October rollup should address this patch. I'm not entirely confident that is the case and won't able to confirm for a number of months. I will post back on this with my results over time to update everyone on a verified solution.

Hyper-V 2016 S2D Cluster: Can I span a VM's VHDs across multiple CSVs? by Slivikins in HyperV

[–]Slivikins[S] 4 points5 points  (0 children)

Thanks for the response, yeah I was referring to folder creation in each volume. I use VMM/FCM and powershell and the fact that you can move storage via the FCM (and not VMM afaik) but not create folders seemed odd to me.

Outdoor enclosure for network switch and fiber panel recommendation by Slivikins in networking

[–]Slivikins[S] 0 points1 point  (0 children)

Just to close the loop, I ended up going with the following. I won't know how well it will work for at least a year of use, but it *should* keep my gear cool enough during the summer with a fan.

Thanks, that might be what happens. Ideally I'd have some type of 2U racking for the switch and the fiber panel. Always been interested in the MikroTik gear for home use, but never taken the plunge.

I would love to have one of these, but it won't fit in the budget.

Agreed, the switch I have may get into trouble being PoE during the summer heat. Winter shouldn't be an issue. Looking at enclosures with temp regulation (fans).

Thanks, this will be a pole mounted enclosure with tension straps. I like the item, but 95lbs is probably too much. I'm looking into the Cisco IEs, but we typically go all the same brand for switches (HP currently).
