BurntOC

I have two unraid servers, both have Intel quad NICs with lan and guest interfaces ("inner", and one also has an iot interface "outer". After originally running one on a 5900X (which ran great after some initial periodic hanging until I moved a few remaining items off br0), both now run on Intel 10/11th gen systems. Anyway, those worked pretty well, also, but after migrating many of the containers from the inner server to the outer one, the outer one has started becoming non-responsive periodically. I finally changed the Docker network type from ipvlan to macvlan yesterday because I hoped it would help with stability, though prior to the migration they had both worked really well on ipvlan and I think that option offers better security - so I'm hoping to revert back at some point. The only thought I had is that I still have a unifi-controller container that is running on a br0 sub interface and maybe the system doesn't like that any more, but it had worked fine that way on the very similar inner server. When it hangs, basically the gui becomes non-responsive first. Usually most/all the containers continue to work, at least for a while, but some recent network weirdness suggests to me that maybe things like swag stop fully passing traffic. Sometimes I can console in, but even trying to intitiate a reboot there doesn't seem to work. I have to do a rapid init shutdown or it never actually reboots. unraid-outer-diagnostics-20230503-0923.zip Anyway, hoping someone can help me figure out the cause. Thanks in advance for any help.

Got it. I thought it was just checking events since the last run. Good to know.

Okay, so I decided to just switch to ipvlan on one of my Unraid servers as a test. Today I wake up to find I am still getting macvlan call trace warnings from FCP. Any idea what's up with that? To be clear, it's not a timing of the message - I ran a check again manually and it is reporting the same thing, but I also checked my Docker settings and yup, ipvlan.

@bonienl I have been using macvlan since like day 1, and while I did have to move some things off br0 a couple of years ago due to crashes. I have br0, br2, and br3 now. I don't have any containers running on br0, just a couple on bridge and the others on br2 and br3, but I am getting the macvlan call traces error from FCP. Is that just something that can be ignored, or do I gain any sort of network benefits from ipvlan if things aren't crashing (e.g. fewer broadcasts or such)?

Yup, seeing the same here with 6.11.5 and FF.

Looks like a few others have seen this lately as well.

Just stopping in to say I encountered this issue out of the blue today as well. About to reboot to get back in.

Guess you have to add a lot of drive space for virtual memory or make your VM memory a lot larger than 8GB....

I have a 32GB 5900X system with a RTX 3070 passed through and 8GB for the Windows VM. Things were working fine for a long time but I rebuilt my server and VM and now I'm running into this and it is crashing Fortnite and other games shortly after I start playing them. Can anyone help me figure out why this would possibly be the case?

Did you have any luck figuring this out? I have a RTX 3070 and things were working fine for a long time but I rebuilt my server and VM and now I'm running into this. Grrr....

Cutting through a whole bunch of stuff, I ran into BIOS flickering and other issues recently so I switched from Legacy to UEFI on my tried and true Unraid server. Booted fine, but starting the VM now results in a black screen and filling my logs within seconds with device not ready errors. Had to add video=efifb:off to my boot options to fix that......anyway, everything else seemed fine, but my Windows guest can no longer find and pair with bluetooth devices though everything looks okay. I created another Windows VM from scratch - same thing. I've tried going back to legacy and just dealing with the flickering at boot but that didn't fix this strange issue. Can someone help me find the solution to why Unraid sees the bluetooth adapter just fine and Windows shows the wizards and devices okay, but it won't let me find and add a bluetooth device in the VM? Thanks.

I’ve been at this a long time, but in an attempt to cut down this long thread even a bit I’m going to try to get to the what I have and what I want to see if one of you experts can solve this. Here’s what I have: · Unraid server running 6.10.3 · I350-T4V2 for Unraid (eth0,eth1,eth2,eth3) · Realtek 2.5GB NIC – passed through to VM on GUEST VLAN · 3 VLANS: o MGMT (corresponds to 192.168.20.x/24) o GUEST (corresponds to 192.168.60.x/24) o IOT (corresponds to 192.168.70.x/24) · Unifi switches and APs with non-Unifi firewall Here are my goals: · Maximize security (especially keeping container traffic mostly in GUEST and IOT networks and segregated from management traffic whenever possible), and keep VMs in GUEST network · Single VLAN per interface I originally had eth0 with an address in the 192.168.10.x range, with the MGMT VLAN on it. · Eth1 was unused · Eth2 had no interface IP, but was on VLAN GUEST with an IP assigned to the VLAN interface. · Eth3 had no interface IP, but was on VLAN IOT with an IP assigned to the VLAN interface. That seemed to work well until recently, but I swapped some servers around and though it seems to be set this way my Unraid gui and SSH access is seeing all sort of slowness and drops. I spoke about it here, but I got no response: https://forums.unraid.net/topic/126512-recent-constant-disconnects-and-web-gui-extremely-slow-diagnostics-zip-attached/ As of right now I can ping from Unraid console and get DNS resolution, but it fails to get a response and things like Community Apps fail to populate. I’ve tried dozens of options including moving the MGMT VLAN to eth1, but I’m running into issues ranging from DNS resolution to continued slowness. Also, maybe I’m just being an idiot because I feel like my brain is broken, but with one VLAN per interface I’d think I could set the appropriate native VLANs on my Unifi switch ports with nothing else tagged and it would work, but it doesn’t seem to work unless I set those as tagged ports on those VLANs. I’ve read literally dozens of threads and web pages about this and I can’t see anyone who has clearly addressed this. I was hoping @bonienl@Vr2Io or one of the other gurus here could tell me how I SHOULD have this set up so that my switch ports are tagged or untagged as they should be, my interfaces are set properly, and maybe even if I have to change my interface rules to re-prioritize interfaces as the slow GUI and disconnects makes dealing with the whole setup unbearable. THANK YOU for any assistance.

Also adding that if I ssh, for example, into other devices off those same switches, I get zero reconnects, adding additional fuel to my theory this is an Unraid issue of some sort....

Just wanted to add that I'd seen the DNS hostname error in FCP and I'd fixed that but the problem remains.

I've been happily running Unraid on a couple of servers for about 2 years or so. Love it. Recently I "swapped" my two servers (one "private" and the other more "media server". Both have I350-T4 quad NICs with a VLAN on each interface, so in practice, what this basically meant was disabling/deleting the IOT interface on the media server, moving sensitive data and containers from one to the other, adding an IOT interface on the "new" media server, and firing things up. It all seems to work, but after doing all of this I am having lots of GUI page timeouts and slowness requiring refreshes to see updates and changes, SSH terminal windows and SFTP windows time out in seconds, and the entire SSH session seems to reconnect every 40 seconds or so. It's happening on both servers, and it did not happen before the move 10 days ago. I've tried deleting and rebuilding network.cfg, changing VLAN interfaces between auto and static, changing default gateways and metrics, and I'm just stumped. Unfortunately, I did also update my Unifi switch firmware around the same time period so I can't absolutely rule that out, but changing back to the previous version didn't seem to help. And I can say that my online gaming, Netflix streaming, Channels DVR container streams, etc. seem to play without any major issues so if there are hiccups being encountered there they are brief enough the buffers are handling it. Most games are FPS with low ping times showing so all of this leads me to believe the culprit is something with Unraid. I was hoping someone might see something screwed up - maybe it was all along and wasn't biting me before, or it could be new. I appreciate any help. unraid2-diagnostics-20220727-1036.zip

I started down this path but what's odd is that I got swag and unifi-controller working fine this way, but of course I'm having to go to Previous Apps to have it actually reinstall the containers and it's showing the apps from BEFORE the transfer, even though I'd deleted all that out of the appdata share, rebooted the server, etc. If I manually browse there it shows all the correct container appdata folders I want it to have, but it doesn't reflect that in the server....

That was going to be my next question when I realized at least part of the issue is I didn't move or swap the docker.img files first. I did just complete another backup of each with the plugin, and everything is shut down at the moment, including Docker services. Can just use the appdata backup plugin and just have each restore from the other's backups? Do I have to do any other prep, like delete docker.img and delete existing appdata folders so they don't "merge"?

So I have 2 Unraid servers, one of which (UnraidA) has containers on custom bridges associated with my management and guest networks. The other has an additional bridge associated with my IOT network, and this one (UnraidB) is my media server. I run about 20 containers on each, but the ones that I'd like to secure a bit more, e.g. unifi-controller, vaultwarden, etc. have been on UnraidA, which has an i7-6700. UnraidB has more of the media-server-related containers as you'd expect, but that server is running on an AMD 5900X with a RTX3070 I have passed through to a VM I use mainly for gaming. At times I need to support transcoding and I don't want to run Plex or Jellyfin in the VM, so I can't support it because the 5900X doesn't have an igpu. I realized I really could just "swap" the servers and then Plex or Jellyfin can use the Intel igpu and I can still use the other box for gaming. I took the step of shutting my containers down and making sure I added or removed shares to keep my sensitive information in a similar posture as to what it is now, and that seemed to go okay. I tried copying appdata for a couple of containers (unifi-controller and swag) from UnraidA to UnraidB and installing them using the same options as I'd used before and firing them up as a test, but I'm failing pretty hard here. Both test containers start just fine, but swag reports it successfully retrieved a certificate then a couple of lines later says ERROR: Cert does not exist. It tells me to check the validation credentials in my cloudflare.ini file but this matches the original, I've confirmed. The unifi-controller won't even accept my username and password. So it seems that due to file locks, permissions, or something else these haven't been transferring properly. Any ideas how to fix this or an easier way to move containers between Unraid servers? They have identical network configurations so at least I don't have to deal with that being different. Thanks for any help from the gurus.

Digging up this old post to see if @baccula or somebody else may have an answer to this? I pass through a drive to my VM, but if I've encountered this message before it was so long ago I've forgotten. I added another SSD to my system yesterday - just to use for Windows boot testing and not defined in the array or otherwise used for VM purposes, but now I'm getting messages with the same error: unsupported configuration: source for disk 'hdd' is not a regular file; refusing to generate external snapshot name

Hi, did you ever sort this out? I'm facing the same thing at this time. Can no longer make form changes after my update to 6.10.

I'm not sure if my issue is exactly the same but I just upgraded one of my two servers to 6.10 just now as well and I'm now getting the certificate is untrusted message, too. Before they both showed secure, and the one on 6.9.2 remains to be fine. Hopefully we can resolve this so I don't have to roll back. EDIT - to be clear, I don't use a custom cert, either. I use Let's Encrypt, mainly wildcard for most everything. My 6.9.2 is still showing LE cert and working as I haven't touched it. EDIT2 - I thought maybe this had to do with not having updated the cert via the MyServers plugin, or whatever it is called. I thought I recalled on one of the early RCs I recalled being told I had to do that at least once. In any case, I tried that and "upgraded my cert" which did appear to generate a new cert, but it didn't fix the issue and I would prefer to use the LE certs anyway.... EDIT3 - Looks like we're getting bitten by the changes noted here https://unraid.net/blog/6-10-stable. I may need to roll back until I understand it better. I know I should read the release notes before upgrading, but this server is my most basic install and I'm not doing anything particularly special. I also ran the Update Assistant and FCP beforehand as well as applied all updates. I think things like this that will affect the vast majority of users probably ought to be copied to an acknowledgement popup in the upgrade workflow.

Awesome. Time to try again it seems.

Anyone know if 6.10-rc3 fixed this issue?

I didn't see this info in the FAQ unless I missed it. Just wondering as 20.10.5 has been out for a long time.

Thanks for reporting this - and for the workaround. Wish I had seen this before I started messing with vfio and messed up my server - triggering a reload and me screwing up lots of other stuff, LOL. In any case, this is still an issue on 6.10rc2.
