  • rrdcachd graphs not working after motherboard change

    Hello omv users


    I've replaced my motherboard due to instability (Intel H170 to Intel W680) and now some of my rrdcached graphs are not working correctly.


    The broken ones are disk usage, load average, memory usage and uptime. The old data is there since before the motherboard change but no new data is being shown. The last hour graph just says -nan.


    I presume something about these graphs are specific to the old hardware. Is there a way to reset them or get them going again?


    Thanks

  • Borgbackup temporary files location

    I'm giving borgbackup a try using the plugin after being unsatisified with various other backup options (duplicati, duplicacy and rsnapshot). Duplicati took 28 hours to backup 525GB on my i5 7500 with 24GB RAM and 7200 rpm disks and absolutely hammered it during. Borgbackup seems really good, and is an order of magnitude faster.


    My concern is where the temporary files are stored. My boot device is an SSD (which is quite old and has a lot of writes already), and I backup a lot of data and I don't want that all written to the flash before it is moved to the repo. It's not clear from the documentation where the files are put.


    Does anyone know?


    Thanks.

  • CUPS docker problem "Internal server error"

    Zitat von geaves

    No it's not!! If you deploy cups as in apt install cups from the cli then yes there is and there are log files, how do I know that because I tried deploying cups as per apt install and the configuration of the cups config file is a BIG PIA.


    The installation of the above docker has a preconfigured cups config and it's accessible and can be edited within the cups WebUI :)


    I know that. The log output was from by connecting to the docker console. The log was there before cups was installed via apt, cups was never installed on the server itself until just now. The web console was only loading when the docker container was running, cups was definitely running in docker. But as I said, it was broken and I was getting those errors in the web console. I'm an IT professional (cyber security currently and previously 10 years of sys admin) so you can trust that I have a rough idea what I'm doing :)


    Here's the diff output, showing the container writes those files



    I just deleted the cups docker container and installed it's directly on server, edited the config file, and now it's working correctly. So, there might be a misconfiguration in my docker instance as I tried four of those cups dockers available on docker hub and they all produced the same error. Docker is not something I have experience with, and every other container I've configured over the last two has works perfectly, so I'm stumped.

  • CUPS docker problem "Internal server error"

    I've decided to install cups directly on the server using apt. I configured the config file to allow access to the web console remotely and it's working perfectly.


    Don't know why docker wouldn't behave for me, but doesn't matter now.


    Thanks for your help geaves.

  • CUPS docker problem "Internal server error"

    I've just redployed that docker with the command you pasted above and the config file is /etc/cups/cupsd.conf.


    Logs are also in /var/log/cups


    Output from logs when I access admin page right now

    Code
    oot@367d923f0fc7:/etc/cups# cat /var/log/cups/error_log

    Interestingly there is a log entry from yesterday but I literally just deleted the container and created it again.

  • CUPS docker problem "Internal server error"

    Running docker container diff I can see which files are modified, some logs are created:

    Code
    C /var/log
C /var/log/cups
C /var/log/cups/error_log

    Among other things, I tried copying a default cups config file and it had the same error.


    It's running on an x86 (Intel Skylake) machine.

  • CUPS docker problem "Internal server error"

    I've just freshly reinstalled OMV5 on my server (previously running 3 and 4 for many years) and have tried to get CUPS back up and running in docker. I've tried four different docker images, including the suggested olbat/cupsd, but they all give me "internal server error" when I go to the administration page. Since they all do it I suspect there is an configuration issue on my OMV docker instance, but it is default running as omv-extras installs it. I've not been able to find any resolution elsewhere on the net.


    I've already got OpenVPN, Plex, Transmission and Kerberos.io running in docker without issue.


    Any assistance would be much appreciated.

  • debian-transmission unable to write to UnionFS volume

    I have Transmission configured to save files to a UinionFS, suddenly it's unable to write to the downloads share anymore. I've reapplied ACLs but that made no difference. There is free space on all disks in the pool.


    If I create a share on a different mount point (e.g. mdraid mirror) it works again, so it's just UnionFS. I can copy files to the downloads share over SMB as my own user account too, the UnionFS is writable.


    Is someone please able to assist in getting this working again?


    Thanks!


    Edit: I've got it working by doing a chmod 777 on the downloads folder. Don't know why reapplying the ACLs didn't fix the problem so still curious if anyone has ideas about that. I wonder if somehow Transmission is running under a different user context, but not sure how to tell.

  • Transmission not working after update

    I updated my OMV 3 with latest patches in update management, one patch was for Tranmission. Since then Transmission isn't working.


    The issue appears to be with the RPC part of it. The web server still serves up the Tranmission page but it gives me an error saying cannot connect to server. Remote GUIs do not work at all.


    Not sure where to look. Anyone struck this? Thanks.

  • Connection to OMV remotely -- Data & Media

    I have OpenVPN configured on my OMV NAS for access to my home network and anything connected to my home network. It's very easy to setup with an OMV plugin and has an Android app, Windows client and native support in most Linux distros. I connect from all three and it works perfectly.


    I don't access my media remotely (although it would work over OpenVPN if I'm connected via a sufficiently fast connection) but I have the Plex port open so my parents can stream media from my house. Plex just needs the port open, remote access enabled on the server side and then you can grant access to an email address associated with a plex.tv account. You don't need sub for their premium service if you are streaming to Chromecast, smart TV or PC, I think only for phone. I have two accounts setup and both allow for unlimited streaming from TV/PC devices.
