    • RE: Why Do Vendors Use MAP Pricing?

      Disclaimer: I own a retail gift shop in a major tourist destination in Florida. Our local economy is 100% tourism based. I’m brick and mortar only. No online sales.

      I carry a few lines of brand name apparel that have MAP policies. I also can’t sell these items online via eBay, Amazon, Aliexpress, etc... Essentially no online marketplace is allowed for these brands. I can sell them at my own business website if I choose.

      I’m actually ok with their MAP policy. It levels the playing field with other retailers around me that may also carry the same brand. Everyone has to abide by the policy for external advertising. Some retailers who have larger purchasing power than me might get those goods at discounted prices from what I can buy them for (i.e. they are buying 2x or more than what im buying in a given year). It’s nice that they can’t advertise a retail price less than the MAP even since their wholesale costs are lower.

      It also prevents “loss leader” sale that is very common with larger box store retailers. I don’t have to worry about a store down the street advertising the same brand for $15 less than wholesale on an item just to get people in the door.

      The third reason I like it is the psychological effect of “perceived value”. I’ve done non-scientific tests in my store where I’ll price two very similar items at two very different prices. People seem to be drawn first to the higher priced items most of the time. It’s quite the thing to witness to be honest. Keeping the MAP price higher keeps its perceived value higher.

      So anyway that’s my two cents working in retail for 25+ years now. I, as a retailer and business owner, don’t mind MAP at all. Take it with a grain of salt. I understand this all doesn’t translate to IT which is what Scott was referring to in the OP. But I wanted to give a side of MAP that perhaps wasn’t considered.

    • Older Axis IP cams & SMB1 issues...

      Anyone have any experience with older Axis cams running firmware that only allows you to mount shares via SMB1?

      I can't seem to get any of my old Axis cameras to mount shares on my SAMBA server running Ubuntu 18.04. I found this little tidbit from Axis: https://www.axis.com/support/faq/FAQ116392

      The cameras in question are indeed running firmware that is before 5.90. So according to that Axis FAQ, they should only support SMB1. But they do not connect to a default smb.conf file. Did SAMBA remove support for SMB1 by default?

      I've tried adding to the smb.conf file

      server min protocol = NT1
      client min protocol = NT1
      

      However, the cameras still won't connect. The errors I'm getting for on the camera logs themselves are:

      <CRITICAL> Nov 10 16:55:04 axis-00408cdbbd05 kernel: [72008.090000] CIFS VFS: Send error in SessSetup = -13
      <CRITICAL> Nov 10 16:55:04 axis-00408cdbbd05 kernel: [72008.210000] CIFS VFS: Send error in SessSetup = -13
      <WARNING > Nov 10 16:55:04 axis-00408cdbbd05 disks[1133]: mount_disks.c : Disk 'NetworkShare0' NOT mounted (due to error) (4)
      

      I'm wondering if its the SAMBA server itself that simply isn't honoring a SMB1 connection. Is there a trick to making sure that SMB1 is still being supported on Linux/SAMBA for legacy devices?

    • RE: Older Axis IP cams & SMB1 issues...

      So I think I "may" have fixed it. I upped the logging level in Samba and noticed that it was a NTLM auth problem.

      So I added ntlm auth = yes which allows NTLMv1 clients to connect in the smb.conf file.

      SAMBA 4.5 changed the default method of NTLM to NTLMv2 clients only. Older clients that don't use NTLMv2 can't connect without changing this setting.

      What a PITA that was to diagnose.

    • RE: Do I need to run AD if I install Server 2019?

      Just as an update to this thread, I upgraded the host to an i9 9900 CPU (8c/16t). There is now plenty of horsepower to chew through the H.264 decoding without having to use Quick Sync.

      I'm happy I was able to keep it virtualized. I've been playing with XCP-NG and blown away how easy it is to use. I think I've found my new love...

      @biggen said in No way to create larger than 2TB virtual disk with Xen or XCP-NG?:

      @scottalanmiller Ok and that's fine. That's what I need to do then. For the camera server VM I'm working on i want it to record to a couple 12TB Exos X drives. So I have to figure out how to pass them through directly. I think Pete S. had a tutorial I need to hunt dkwn.

      Why stay with XCP-NG? why not move over to KVM?

      I've used KVM and really like it. Been running it on a Debian host for yeras. For the new host build, I wanted to try something different mainly. I was impressed with Xen and when I found out about xcp-ng I had to give it a spin.

      @olivier Great! I think I will just pass through the disks and be done with it. I could have gone the NAS route, but I have enough local storage to not have to use that option.

      Frankly, @Obsolesce might be the rightest here. Perhaps don't virtualize. Your storage requirement makes migrating to another platform more challenging - not saying not doable. and you plan to have a dedicated machine - with, now, likely directly provisioned storage due to the hypervisor of choice limitations.

      It's one thing to want to get more experience at something - but at the cost of an enterprise implementation seems foolish at best. Making the the most sound IT decision for the job at hand should be the goal - not furthering your education (that's what labs are really for).

      I have no desire to migrate this VM. It's just running a camera recording software suite for my business. Honestly, it's nice to have but not a necessity. I used to run it virtualized via KVM as well and also passed through the disks to make managing that much storage easier.

      At any rate, disk pass through was successful for xcp-ng. I appreciate everyone's input.

    • RE: Reconsidering ProxMox

      I've been playing with Proxmox quite a bit. Still love xcp-ng but Proxmox does somethings that xcp-ng doesn't. A built in host management interface for instance is wonderful.

      I do wish Proxmox supported MD. I know I can easily configure it but don't really want to do that.

    • RE: NVMe and RAID?

      @travisdh1 Yeah it would be a Debian VM providing the SMB share (via Proxmox or xcp-ng) so MD RAID isn't an issue. Proxmox can use ZFS Raid 1 whilst xcp-ng can do standard MD RAID.

      Edit: Dell even has that BOSS add-in system that allows for a RAID 1 bootable volume just for the OS. The NVMe drives could be VM storage only if I go that route.

      @PhlipElder Excellent! Bookmarking your blog as well.

      On a side note, I really really like Mangolassi.it Actual realife sys admins who you can bounce stuff off and ask questions. Glad this site is doing well. Its always my first search for something technical that I know someone in here will have dealt with at some point in their career.

    • RE: XCP-ng 8.0 is available

      @scottalanmiller Ok, thanks for that Scott. I'm going to try running that camera software I made another thread about in a VM via XCP-NG. I upgraded the host to a 6C/12T I7 8600. If I can't do it with that much horsepower, I'll just go back to my original plan of a single host (Win 10) system for the cam system.

      So far loving XCP-NG with XO and XenCenter. What an amazing piece of software. I wish I had seen this years ago before I shelled out money for an ESXi Essentials license.

    • Xen and Mdadm?

      I currently run ESXi in my business for production. However, I'd like to try out Xen at home as I have heard so many good things about it.

      I currently have a physical Ubuntu Plex/Nas server at home. Ubuntu is installed on a single SSD while my media for the NAS is installed on a 6TB mirror being managed and run by mdadm. This box has no hardware RAID and I'd like to keep it that way.

      What's my path here to virtualize this host via Xen whilst using mdadm? I'd like to get an additional SSD so that I can run a mirror for the VM datastores and a mirror for my actual media. From what I have read, one seems to kind of have to hack Xen in order for it to play nice with Mdadm. Was Xen only designed to be run via Hardware Raid?

      I'm also confused on what I would need to download. Is Xenserver the proper download or is it just "Xen"?

    • RE: Xen and Mdadm?

      Wow I got a crash course in the finer naming art of Xen. Very cool. BTW, I should have kept my same username name from Spiceworks when I joined here. I recognize both Dustin and SAM from over there.

      I'll check out that tut you linked to Dustin. Would I be correct in saying that while Mdadm works just fine it isn't really "supported" in this configuration with Xen? In other words, is this not something you would do on a production machine?

      Thanks Scott that is very helpful. I've enjoyed playing around with MD on my Ubuntu Server. Learned a ton. I think moving it to a VM via XenServer sounds like another good learning expierence.

    • RE: KVM Snapshot/Backup Script

      @stacksofplates Ah ok. I misread the script last night when I was looking it over. I thought since it was renaming it “snapshot” that it wasn’t copying the base image. I missed the $diskpath variable at the top of the script. Thanks for clearing that up!

      This is a handy little script. I ended up installing the QEMU guest agent in my VM so I’ll add the “—quiesce” switch to the backup command line. Thanks for sharing this!

    • RE: Do I need to run AD if I install Server 2019?

      Ok wow. Well that clears up that I DONT WANT to run Win Server...

      The issue is really Blue Iris. It decodes the H.264 byte stream. It doesn’t play well with Nvidia so it’s recommended to run it bare metal and let the Intel CPU and Quick Sync handle that. The folks that are running Win 10 or Server bare metal and then connected all their cameras to that I guess aren’t in proper licensing.

      I guess I can look at some other VMS options. I know that NX Witness can run on Ubuntu so I could install Hyper-V core and run an Ubuntu VM for that. It’s just costly since NX Witness chargers per camera for licensing.

      Having to think about it some more... Thanks for the suggestions guys. I knew I could count on advice here.

    • RE: Do I need to run AD if I install Server 2019?

      So I think I’m going to stick with Blue Iris but just build out a separate machine just for that. I’ve got plenty of parts lying around to white box it. It’s features and GUI are just too good and other competing surveillance software wants licensing PER CAM while Blue Iris is a flat fee.

      Seems silly to have a physical host for one specific application in 2019 but unless I want to pony up $$$ for another type of software, I guess this is it.

      I’ll run it on Win 10. Reading on the intertubes, that seems to be working for the populace. It’s a shame it’s not designed for a more “production ready” environment. Maybe I need to bitch and moan on their forums for an “updated” VM ready version.

      Pete, I actually found your post (at least I think it was from you, I was tired last night) from a year ago or so on here about doing exactly that. I may test that method out as well.

      Yeah its strange that Xen's base file system is still ext3. I mean, that is very very old. Wonder what the holdup is to move it to at the very least ext4?
