Hi everyone,

one of the disk that was used with the MergeFS plugin failed and now i'm stuck in emergency mode.

I tried both "exit" and "systemctl default" but nothing works.

How can I boot into OMV now?

I had some issues with usb keys and sd cards regardless of this plugin, maybe because some software like plex still write too much.

I would rather suggest a cheap SSD connected via usb.

Got it! Thanks to everyone!

You should look at techodadlife videos or DB tech. They have many guides that are really straight forward.

Also if you look at other platforms, you would see that basically everyone use docker for everything when it comes to homelabs. It's easy to use and manage and doesn't require the OMV/freenas/unraid developer to waste time in a plugin.

Hi everyone, can someone explain the difference between those two plugins to me?

They seems the same thing and I don't know which should I use

I cleared the errors and launched a new scrub. I don't get why the file is indicated as corrputed. I opened it and it worked.

Hi everyone,

because of some blackout I had in the last few days I now have some checksum errors on my ZFS raidz1 .

This is the message that I got tonight.

What should I do now? Do I need to backup everything and recreate the pool?

SMART seems fine. I run a long test this morning to be sure.

Also I'll run a backup tomorrow just to be sure.

Hi everyone,

tonight I recieved this notification:

What doesit mean? Do I have to replace sde? How can I know which file is affected? By this error?

I know that TrueNAS and OMV aren't really competitors. they aim for different targets of users.

The biggest question is if with both Canonical and TrueNAS shipping a distro with ZFS included it means that everyone will be able to do that.

Hi everyone,

I just read this news about TrueNAS. They're making a new version based on Debian that it will natively support ZFS!

https://www.ixsystems.com/comm…ject-truenas-scale.85203/

Now my question is: since they are able to do that, do you think that the licences issues of linux and ZFS are solved thanks to OpenZFS 2.0 ? In that case, there is any hope to see ZFS natively supported by OMV?

Why not remove the normal kernel? There is a button to do that in omv-extras.

Because I totally missed it! I removed it now!

Did you lost your share configuration or was it still available after the import of the pool?

The root cause for the problem may be explained here: Shared folders going N/A for device corrupts USB Backup

All the sharedfolderst stopped working and I had to recreat them.

Everything else was still working.

Up, there is some way to avoid this issue?

Honest suggestion after having usb key or SD cards dieing: install OMV on the cheapest SSD you can find (64/128GB) and stop worring about it.

There is the wake up plugin. I also use WoL packets sometimes.

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
