No. Does you OMV4 system only have one drive? I think doing a p2v move is going to be messy if you have lots of drives.

I am short before going to bed…

No, it has a bunch of drives (8x WD Red 10TB Raid-Z2). But I don’t want to passthrough the disks at the moment.

I am going to do it the following way on the new omv6 machine:

1. install the proxmox kernel
2. install openmediavault-zfs
3. import the zfs pool / filesystems
4. configure the nfs and smb shares
5. configure the users and groups
6. install and configure portainer (Do we have a better tool nowadays?)
7. configure my docker containers (maybe via backups or completely new)
8. create a omv4 vm, where only FHEM and it’s different modules and Homebridge services run (have to deactivate smb/nfs/docker/zfs to not confuse the system)
9. when I find the time, migrate FHEM to a new structure

What do you think about it?

Thanks Hoppel

Hi BernH

so I installed openmediavault6 on a new disk, updated the system to the latest and greatest, installed omv-extras and executed the command you named. There was one little issue with the argument -o. It needs to be -O.

@omv6:/data# qemu-img convert -o qcow2 /dev/sda /data/vms/omv4.qcow2
qemu-img: Invalid parameter 'qcow2'

@omv6:/data# qemu-img convert -O qcow2 /dev/sda /data/vms/omv4.qcow2

Now I have the following file:

@omv6:~# du -h /data/vms/omv4.qcow2
124G    /data/vms/omv4.qcow2

Any idea about the ideal vm configuration?

Thank you so much!

Hoppel

Thanks for this hint.

I googled your command and found the following thread:

[solved] Migrating physical drive to QEMU image / partition of another drive

I have been using an old, beat up HDD for my virtualized machine, which I pass to QEMU with the option -drive file=/dev/sda,format=raw. I just got a new HDD…

forum.level1techs.com

The first answer acknowledges what you wrote. Seemingly it’s that easy to convert a physical disk to a qcow2 file.

But the opening post of that thread describes what I planned to do and see the following:

-drive file=/dev/sda,format=raw

Is this configurable in the openmediavault-kvm gui? What do you think about it?

I don’t have openmediavault6 installed at the moment. I will do that the next days.

Thanks again

Hi,

maybe someone here can help me with this?

Thread

Boot OMV4 on a physical disk in a kvm guest

Hi,

was away for a long time and didn’t have the time for omv. I am still using omv4.

I am in a stuck situation because of my home automation software (FHEM). I installed a lot of custom FHEM modules via apt/curl/npm/git.

Now I want to get out of this situation and am thinking about how to proceed.

OMV now has a KVM module. Great! With this I can go the route without Proxmox now.

I will not be able to do the migration in one step, so I have the following idea:

1. Install omv6 to a new SSD
2. Install

I will not be able to do the migration in one step, so I have the following idea:

1. Install omv6 to a new SSD
2. Install omv-extras and openmediavault-kvm
3. Passthrough the old SSD with my omv4 installation to a newly generated kvm guest on omv6 and boot it
4. Migrate service after service from my old omv4 installation to a new docker container or an own kvm guest

What do you think about it? Is this a possible and working way? Any idea, what I have to do to get step 3. working?

Thanks Hoppel

Ok, thank you for the information. I will be patient.

Regards Hoppel

Any idea, when openmediavault-zfs will be ported?

No stress at all. My omv is absolutely stable. I only want to understand the priority of this plugin in the big picture.

Thanks and regards Hoppel

I will not install any external plugins anymore because of security issues.

Ok, I understand. What do you think about WSC-Connect which you can find in the woltlab pluginstore as an alternative to tapatalk?

Is this an external plugin?

Hi guys, I recognized that Tapatalk isn‘t working anymore.

Will the Tapatalk support get back?

Another solution may be the WSC-Connect (as a supplement to Tapatalk or alone) for woltlab forum software:

I am already using WSC-Connect for three forums.

What do you think about it?

Thanks and regards Hoppel

Nobody else here interested in Tapatalk or WSC-Connect?

votdev Any plans to implement at least one of them?

Yeah, that’s fantastic! I think, I would also go the Ubuntu path, because of the official zfs support.

Would any mod please close this thing? Thanks!

Why? This is a good starting point for people migrating from omv4 to omv5.

I am still using omv4. I don’t have much time at the moment. In my opinion this thread solves a lot of typical problems while migrating or directly starting with omv5.

Please don’t close this thread until omv5 is marked stable.

Thanks and regards

Good idea!

Thank you so much!

Hast du mal darüber nachgedacht, den config-Ordner auf eine HD auszulagern, die immer läuft, bspw. die Systemplatte. Die schläft normalerweise nicht...

Wenn die Systemplatte abraucht, wäre der config-Ordner allerdings auch weg. Ein regelmäßiges Backup wäre also nicht schlecht...

Gruß Hoppel

Thanks guys! I do not plan to upgrade.

Regards Hoppel

Can you describe the trouble with zfs in more detail please?

Thanks Hoppel

Ok, und was hast du unternommen, um es zu lösen?

Gruß Hoppel

Welche Festplatte geht nicht in den Standby? Hast du eine Extra-Festplatte für deine Aufnahmen oder zeichnest du auf die Systemplatte auf?

/dev/dvb liegt auf der Systemplatte. Ich habe keine Ahnung wie oft TVH den EPG aktualisiert und damit auf /dev/dvb zugreift. Evtl. hängt es damit zusammen.

Problem is: I can't boot the VM with the LSI Passthough... something weird going on booting the LSI Bios... I need to better investigate how to do it.

What is th error message?

Quote from magnosantos

Anyway it would be nice to have KVM inside OMV, this could open another scenarios...

Did you already try cockpit?
