    Unraid instance becoming wildly unreliable

    in General Support

    Posted

    Hello All

     

    For months/years Unraid was rock-solid for me.  But over the last ~4 months, it has become increasingly unstable.  By this I mean the entire system becomes unresponsive and I must pull power to get it to respond.  Initially it was maybe once a month this would happen.  Then it became weekly.  Now it is daily & the system is no longer reliable at all.  There is no rhyme or reason to when it decides to hang -- sometimes in the middle of the day, sometimes in the middle of the night. Sometimes the system is dead as a door nail.  Other times I can get some limited response from the web UI, but this usually hangs hard within a minute or two of clicking around trying to figure out what is going on.

     

    I've tried looking at logs, but the system logs only seem to exist from when the server is restarted -- meaning I can't see logs from the hang, only starting from the reboot.  Surely there must be older logs than that, but I can't find them.

     

    Any suggestions on how to diagnose this would be appreciated!

    New Remote Vulnerability for Samba (CVE-2021-44142 & CVE-2022-44142)

    in Security

    Posted

    Am I the only one troubled by the seemingly non-existent cadence for security patch releases on unRaid? Don't get me wrong - I love me some UnRaid and talk it up every chance I get.  But I'm wondering whether I should be heaping quite so many praises Limetech's way.

     

    We are now 10 months since 6.9.2 stable was released.  That's a long time.  Lots of CVEs posted since then.  CVE-2021-44142 (the one being talked about above) is only the latest high severity issue (a 9.9 out of 10).

     

    6.9 was followed a month later by 6.9.1 (CVE-2021-23841, CVE-2021-23840) and then a month after that by 6.9.2 (CVE-2020-27840, CVE-2020-27840).  That's the kind of cadence I can feel confident in.  But after April 2021?  Nothing.

     

    I would like to see what published policy Limetech has for security patching.  I'm not aware of any (please correct me if this is wrong).  Assuming no security patching policy exists, we should be pushing for one, and then help make sure they live up to it.

    Converting Docker Run commands to UnRaid

    in Docker Engine

    Posted

    Hi All-

     

    I've been struggling with creating custom docker containers on UnRaid -- specifically figuring out which elements on a docker run command belong where when it comes to UnRaid.

     

    To cut to the chase, I'm trying to follow the quickstart guide for Cassandra DB (https://cassandra.apache.org/_/quickstart.html) and there are a number of docker run commands for establishing the dockerized instance and then interacting with it.  The area where I'm particularly having issues is with the --network option.  Here are two examples:

      

    docker run --rm -d --name cassandra --hostname cassandra --network cassandra cassandra

docker run --rm --network cassandra -v "$(pwd)/data.cql:/scripts/data.cql" -e CQLSH_HOST=cassandra -e CQLSH_PORT=9042 nuvo/docker-cqlsh

     

    In both cases I remove elements which are handled differently by unraid (e.g., the rm, setting the name etc) but the network option has me baffled.

     

    Any pointers for this?  The docs and other posts I've found don't really help.

     

    Thanks,

    Using a physical KVM switch with Unraid 6.9 destabilizes system

    in VM Engine (KVM)

    Posted

    Still seeing a few messages in the logs.  I also ran into some issues this morning that seemed to be associated with the built-in hub of a dell keyboard.  USB manager really did not like the hub, especially if I plugged the mouse into it.  When I connected the mouse directly to the KVM switch, USB Manager was much happier.  

     

    Here's the latest log with a few errors in it -- not sure if these are anything to be concerned about:

    Using a physical KVM switch with Unraid 6.9 destabilizes system

    in VM Engine (KVM)

    Posted

    My KVM does have dedicated mouse and kdb ports.  It also allegedly does EDID.  I've never had an issue with monitors not being in the "right place" when switching between devices.  That all being said, this is hardly the creme-de-la-creme of KVM devices.

     

    I ran several tests and captured diagnostics.  I also made a timeline of what I was doing at what time.  Finally, I have a diagram of how things are physically connected up.

     

    Hopefully this helps identify if I'm doing something wrong, or if there is an issue inside unraid usb handling.

    Using a physical KVM switch with Unraid 6.9 destabilizes system

    in VM Engine (KVM)

    Posted

    Hello-

     

    I've been trying to use a physical KVM switch to move between both physical PCs and VMs running under UnRaid 6.9.  This has not proved to be successful (for the Unraid VM portion) -- to the point where simply trying to switch to an Unraid VM with the KVM can destabilize the entire system.

     

    In the most innocuous case, the VM simply does not recognize the mouse and keyboard when the KVM switch is used.  To clear this problem, I must unmap and then remap USB devices from the VM for them to be recognized.  Sometimes I have to restart the VM to clear the issue.  Once cleared, the mouse and keyboard behave normally.

     

    A more significant issue is when switching to the VM not only results in the keyboard and mouse not being recognized by the VM, but also the webgui of the Unraid server becoming unresponsive for 60-120 seconds.

     

    The most significant issue is when switching to the VM not only results in the keyboard and mouse not being recognized by the VM, but the webgui reports it is no longer able to access the unraid OS thumb drive and the server must be either manually rebooted, or crashes.  This has occurred 3 times over the last 2 days of testing this.

     

    Clearly, the KVM switch is causing something bad to happen within the USB management aspects of UnRaid.  Whether the KVM switch is uncleanly attaching/detaching the USB devices is not clear.  Weirdly, other USB devices (e.g., USB headset, USB Webcam) switch fine every time.  It's only the keyboard and mouse which seem to cause mischief.

     

    I would be happy to help troubleshoot this more.

    Using a KVM switch with an unraid virtual machine

    in VM Engine (KVM)

    Posted

    I'm in the same boat as others above - need to use my physical KVM switch to move between unraid VMs with my single keyboard and mouse.  As other have said, when the kvm switches to a different unraid VM, things lock up.  Right now I'm just trying to switch between my laptop and a single unraid VM.  So I have mapped the USB devices for mouse and kbd to that vm.  When I first save the config, it works great.  I switch the physical KVM to my laptop, and that works great.  I switch back to the VM and the KBD and Mouse are dead.  I have to unmap them and remap them in unraid control panel to get them to work again.

     

    I'll try the suggested solution to see if that works.  If not, I'm eager to work with someone to figure out whats going on & what to do about it.

     

     

    [Support] GitLab-CE

    in Docker Containers

    Posted

    I am tearing my hair out trying to actually access the GitLab CE instance from a development workstation.  Accessing the WebUI via unraid works fine - I can peruse the settings the live long day.  As I mentioned above, I even have emails being sent for new users now.  But actually trying to connect via a git command line, as it shows for the project I set up in the WebUI just isn't happening for me.  I follow the command lines to the letter, but always get a login failure when I try to push to master:

     

    git@unraid: Permission denied (publickey,password,keyboard-interactive).
    fatal: Could not read from remote repository.

     

    I am completely baffled why this is not working for me.  Any can set me straight?

    Does anyone out there have email support working?

    I just got gmail based SMTP working today.  If you check the production.log for your install you will likely find password failures in there from Gmail.  The trick is that you need to understand that Gmail considers GitLab-CE to be a "less secure app" and will automatically block any login attempts from it *unless* you configure your gmail account to allow "less secure apps" to connect.  In my case, I'd created a new gmail account for it but had not enabled less secure apps.  As soon as I did, email started flowing normally.
