    Just as an FYI, this release adds in some shares vs cache pool settings.


    Getting this:



    Share appdata set to use pool , but files / folders exist on the cache pool

    Share domains set to use pool , but files / folders exist on the cache pool

    Share syslogs set to use pool , but files / folders exist on the cache pool

    Share system set to use pool , but files / folders exist on the cache pool


    I don't understand. They are all set to "Only : Cache" so files/folders should exist there? I have two pools (named cache and temp_hdd), 3 devices in total.

    After changing the Local TLD, I now get the same FCP error, but this time it's due to a case mismatch - the certificate uses all lower case domain name, but my Server Name setting uses an upper case letter. I'll change the server name setting, but as host and domain names are case insensitive, I suggest that FCP do a case insensitive match.


    Got the same warning. Invalid Certificate 1. Server.lan vs server.lan.

    Yeah I thought about that, but then again it used to work with the standard access settings so I figure I'm missing something else.


    Is there a way to learn about and test permission settings from within a docker?


    Something changed with permissions when Unraid got updated a while back.

    Anybody? I'm new to dockers and just don't understand why duplicati is now plagued with access restrictions.

    You could try setting both PUID and GUID to 0.
    Please note that this will give the container full access to the file system (everything).

  5. latest is v3 for me. I changed from preview to latest a couple of minutes after the docker build and page was updated. Sonarr was on version for preview and upgraded to when changed to latest. I did not remove the tag, I changed linuxserver/sonarr:preview to linuxserver/sonarr:latest and updated.

    Doesn't for me.  The "du" of /var/lib/docker under both an image and as a folder are roughly the same


    There must be some problem here. 

    My /mnt/cache/system/docker/dockerdata (docker in folder) is about 72-79GB if I check with du. My old docker.img had a max size of 30GB and was near half full. 

    If I check using the unraid gui and click calculate for the system share I get about 80GB used but when I use df -h i see that my cache drive only has 19GB used.

    Maybe a bit off topic, but do you use dockers for Home Assistant MQTT @Niklas? My power usage is now litterally showing in kind off encrypted style in the log. lol

    Only when I am not on the website it won't show anything.. xD


    Not using MQTT (yet).

    I think it has something to do with networking. I don't know if this bug report could help

    Rather than try and save the docker.img, just recreate it.  Less hassles.


    Also, far easier rather than doing Add Container to add them back in one at a time to instead Apps, Previous Apps and check off what you want then hit Install.  

    Far easier, yes. I knew I had that information somewhere locked away in my brain. Thanks for pointing that out!
    I just moved from docker.img to directory and added my 20 containers back using the add container button. Wasted some time there. ;)

    I might have found out that Home Assistant doesn't actually 'abuse' the docker image file as it's storage location. So I am more hopeful now. Will now shut dockers down and backup the image. Then need to have 1 docker online at 00:00 CET. After that upgrade time. I'll keep you updated lol.

    Thanks for the help so far though!!

    Also running home assistant. The most abuse I saw was writing to the home-assistant_v2.db (recorder/history). I moved home-assistant_v2.db from the btrfs cache to my unassigned hdd in 6.8.3. With the multiple cache pool support in 6.9, I removed unassigned devices and added the hdd as a second cache pool formatted as XFS. Just for use with stuff that writes lots of data to save some ssd life. No critical stuff.

    Here it's now 23:29. So I am trying to get this fixed before Monday morning. I will update Unraid asap.
    I will ofcourse backup the image and such.



    Is there a way to transport/move the dockers from the img to the 'new location'? Or is what you said the way to get the docker back with it's settings?

    Same time-zone as me.
    Yes, that what I said. You can try the "add container" button now before upgrading and you will probably see what I mean. Your dockers with settings will be in the "Template:" dropdown list (under "User templates").

    Has 6.9 been stable for you? Been waiting for the new big release, but if it stable and the docker can be fixed, that would be perfect!

    57 days uptime without any problems. I just moved from docker.img to directory like three hours ago, running fine.

    Hey guys. I had this issue and moved to the newest beta and it was fixed. You can also use the below command but its not persistant after boot.


    mount -o remount -o space_cache=v2 /mnt/cache



    I hope this helps

    As i understand, that command is not needed anymore with the 6.9-rc2. It only mitigates some of the writing amplifications but it's a start. :)

    I do worry a bit about the solution as this guy 'lost' his dockers. Which would in my case mean I lose most of the Home Assistant configuration (not configuration files, but things like built-in integrations, internal user settings etc.)


    You don't need the solution mentioned there if running 6.9-rc2. In 6.9 you can select a dir to store your docker data instead of the docker.img (in the gui).

    You will lose all of your dockers but you can easily add them back with all your settings intact by using the "ADD CONTAINER" button. Select your docker from the "Template:" dropdown box and click apply.

    It's been a long time since start of this post. I actually am having the same issue right here. Whilst checking at the report, I am scrolling trough pages and found only 1 solution from @S1dney (listed onto page 2). This big writing started when I started using MariaDB docker, but I've seen before that the cache has always been very busy.

    My SSD's are running RAID 5 unencrypted with a total of 300 million writes in 41 days (started using mariadb docker since last 5 days).


    Any suggestion how to fix? Or is the method listed on page 2 still the workaround to go with?



    Look in this report thread:

    The rebase was forced by not being able to compile domoticz anymore on alpine. Unfortunately we can't do anything with custom scripts.

    If the packages you add would benefit others also, you can make a docker mod so more people can benefit from it. There should be more info about docker mods in the readme on GitHub.


    I will add a script that fixes permissions on usb devices in the container. If anyone have devices named other than ttyACMx, then please tell me so I can add it to the script.


    I have one ttyUSB0 also



    And three ttyACMx

    My domoticz was updated to 2020.2 today and it broke my zwave. I'm getting 'Failed to open serial port /dev/ttyACM0'. This was working fine until this morning update.

    Same here. Broke all connections to my USB devices. You could try doing chmod 777 /dev/ttyACM0 in the server terminal and restart Domoticz. If it works, add the command to your go file.

  16. I add some trackers using the "Automatically add these trackers to new downloads" but that setting and field reset when restarting the container. 


    In qBittorrent.conf:


    After container restart



    This could of course be a problem with qbittorrent itself. hmm.

    You're saying you're moving the mariadb location between the array, the cache location (/mnt/user/appdata) and directly onto the mountpoint (/mnt/cache).

    The screenshots seem to point out that the loop device your docker image is using is still the source of a lot of writes though (loop2)?

    Yes. I tried three different locations. /mnt/cache/appdata, /mnt/user/appdata (set to cache only) and /mnt/user/arraydata (array only).

    The two first locations generate that crazy 12-20GB/h. On array, it was like 10x+ less writing.

    The loop device also does some writing I find strange, yes. Wrote about this before noticing the high mariadb usage..

    I will read your bug report and answers.

    Edit: this is just by keeping an eye on mariadb specifically. Other containers writing to the appdata dir will probably also generate lots of waste data including the loopback docker.img.

    One way to avoid this behavior would be to have docker mount on the cache directly, bypassing the loop device approach.

    I had similar issues and I'm running directly on the BTRFS cache now for quite some time. Still really happy with it.

    I wrote about my approach in the bug report I did here: 


    Note that in order to have it working on boot automatically I modified the start_docker() function and copied the entire /etc/rc.d/rc.docker file to /boot/config/docker-service-mod/rc.docker. My go file copies that back over the original rc.docker file so that when the docker deamon is started, the script sets up docker to use the cache directly.

    Haven't got any issues so far 🙂


    My /boot/config/go file looks like this now (just the cp command to rc.docker is relevant here, the other lines before are for hardware acceleration on Plex)

    # Load the i915 driver and set the right permissions on the Quick Sync device so Plex can use it
    modprobe i915
    chmod -R 777 /dev/dri
    # Put the modified docker service file over the original one to make it not use the docker.img
    cp /boot/config/docker-service-mod/rc.docker /etc/rc.d/rc.docker
    # Start the Management Utility
    /usr/local/sbin/emhttp &



    loop2 is the mounted docker.img, right? I have it pointed to /mnt/cache/system/docker/docker.img
    What did you change in your rc.docker?
