Hi everyone.

I'm using proxmox kernel since I use ZFS. Recently I updated the normal kernel by mistake and so I didn't set the proxmox kernel as default one.

Of course ZFS plugin was't able to work so I had to restart the NAS with the correct kernel.

After that, ZFS correctly imported the pool, but OMV was't able to use it. In the file system section it had "n/a" in every section.

I had to uninstall zfs plugin, delete the zfs folder (it was empty of course), install zfs again and import the pool.

There is some way to avoid the initial issue? Should I switch to normal kernel instead of proxmox?

Hi everyone,

a while ago I followed this guide from TDL:

Soon after I encauntered a problem: during night I suspend my nas and at startup the vpn client is unhealthy and all the containers that use it as network interface won't be able to connect to internet.

So I made a script that will check the vpn status and restart it until it's healthy and then restart every container depending on it.

I hope it will help someone

#!/usr/bin/env bash
if [ $(docker ps --filter "name=vpn" | grep -c "(healthy)") -eq 0 ]
        then
                echo "vpn is unhealthy :< "
                #c is the time to wait before before starting again the container in case it will be stuck in the "starting" state. 
                #Since seelp is 30s, with c=10 it will wait 5 minutes.
                c=10
                while [ $(docker ps --filter "name=[INSERT vpn CONTAINER NAME HERE]" | grep -c "(healthy)") -eq 0 ]
                do
                        if [[ ($(docker ps --filter "name=[INSERT vpn CONTAINER NAME HERE]" | grep -c "starting") -eq 0) || ($c -eq 10 )]]
                        then
                                echo "Restarting vpn"
                                docker restart vpn
                        fi
                        sleep 30
                        c=$(( $c - 1 ))
                        if [ $c -eq 0 ]
                                then
                                        c=10
                        fi
                        echo "Countdown to next restart - $c"
                done
                echo "vpn is healthy now :D"
                docker restart [INSERT depending CONTAINER NAME HERE]
                ....
                docker restart [INSERT depending CONTAINER NAME HERE]
        else
                echo "vpn is healthy"
fi

Scripts are run in a shell environment.

It is possible that, unless you specified in the shebang what shell to use, the script is using another shell than the one you are using when you run the script from the cli. I am not sure what script scheduled tasks use by defalut? Possibly the default for the user that the script runs as? I have never tried to use scheduled tasks, so I don't know. I use crontab from the cli.

For example, this shebang as the first line in the script make sure it runs in bash:

#!/usr/bin/env bash

...and this in sh:

#!/usr/bin/env sh

And the syntax can vary a little between different shells. That might be why the script riuns OK from the cli but not as a scheduled job?

In my experience some shells are not correctly setup in OMV. At least that was the case in OMV4. But it seems that bash was correctly setup. Try to set bash as the shell to use both for the user and in the script, unless you have good reasons to use some other shell and verify that it is correctly setup.

#!/usr/bin/env bash

Thanks! That line worked!!

Tonight I'll prepare a post

Hi everyone!

I created a script that I will soon post in the guide section as soon as I finished all testing

My latest issue is running it throught scheduled jobs.

If I run it from cli using

/home/Script/test.sh

it works fine.

If I run it from scheduled jobs I recieve this error:

This is how I created the job:

I don't get why if I run the script from cli it work while if I run it from cronjob I recieve an error.

OMV\ExecException: Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export SHELL=/bin/sh; sudo --shell --non-interactive --user=root -- /home/Script/Restart_downloader.sh 2>&1' with exit code '2': /home/Script/Restart_downloader.sh: 7: /home/Script/Restart_downloader.sh: Syntax error: word unexpected (expecting ")") in /usr/share/openmediavault/engined/rpc/cron.inc:177Is this a OMV bug?

Hi everyone!

I need some help for my configuration. I followed the guide from TDL to use NordVPN container with other container and it's working great.

The issue is that at night I put my server on suspend, and when I wake it up the vpn container is in "unhealthy" mode and because of that all other containers won't work.

Now I need to do this with a script but I don;t know how to write it

c=0;
docker restart vpn;

While ([container "vpn" status] = unhealthy) {
if c=6
then{ c=0
docker restart vpn}
else { c=c+1
wait 1 minute}
}
docker restart XXX 

Basically it will restart the vpn container, check every minute if it's healthy, if it waits more than 6 minutes it will restart it again. when it's healthy it will restart all the other containers depending on it.

Suspend. I don't shutdown because otherwise wake on lan wouldn't work

Hi everyone,

during night I usually suspend my NAS using autoshutdown.

The issue is that after resuming it some container won't work correctly. Is it possible to set up a script that automatically restart them in some way after I resume my NAS?

Update: solved.

I didn't know that I had to remove the ports from the torrent client configuration. I found the error in the portainer logs .

Run All Your Dockers through a VPN

My VPN

First of all: thanks a lot for this video!

I tried multiple times but everytime qBittorrent/Trasmission won't start. NordVPN is starting fine, nginx too, but then I don't have the torrent client running

Also I noticed that in the video the ownership is "public" while in my case it's administrator:

Do you know how can I solve this?

My bad, didn't see the link about how to limit how much RAM ZFS will use.

So I jusu should run this 3 commands from cli right?

echo "options zfs zfs_arc_max=1073741824" >> /etc/modprobe.d/zfs.conf
echo 1073741824 > /sys/module/zfs/parameters/zfs_arc_max
update-initramfs -u

I don't really think I need more than 1/2GB of RAM since most of my file are media files.

I'm not really sure what will improve if I give 1/2/4GB of RAM to ZFS.

tried to edit the file, but after rebooting it will return to 0.

For now I only edited the file zfs_arc_max, then rebooted. Lets see

exactly. the only thing is that plex won't work while nordvpn is up

After editing it, do I need to restart my server?

right now it's using nearly 4GB. For my usage is a little too much since I only have 8GB of ram.

Hi, is it possible to lower how much RAM ZFS will use? In zfs_arc_max I have "0". Can I change that value so that ZFS will use no more than 2/3GB?

Considering that with OMV 4 I had an average usage of 25% and now it's nearly 60% I wondered if I did something wrong, maybe with ZFS.

Hi everyone,

I don't get why my RAM is nearl full even ifall my containers combined use around 1,5GB.

As you can see I only have 900GB free even if I should have only 20/25% of RAM occupied.

How can i check what it's using all this ram?

Update: not sure what happen but now I can see Data in the Device list

Maybe I wasn't clear:

1) I created the pool Data

2) I created 4 sharefolder using Data

3) Now I need to add a 5° sharedfolder but I can't select Data from the Device list, I can only see the backup disk.

I don't get why Data and the already created sharefolders are working even if

- I can't find Data in the device list to create a new sharefolder

- The 4 sharefolder instead of /Data or /Data/anime have n/a and I can't edit them. If I try to edit them I get the error of the preview post.
