Does my planned OMV Installation / setup make sense? [Help, i'm a beginner)

Dawei · Sep 16th 2023

Hi!

I am completely new to this whole scene.

This is my hardware:

- Raspberry Pi 4 (8gb version)

- Micro SD Card 64gb class 10

- 1TB external ssd

What i want:

- OMV (currently installed) for my first NAS to store private documents, pictures and videos

- Docker installed through OMV, to install containers like Home Assistant and such stuff

First Problem:

Currently i am struggling to install Docker inside of OMV, every guide i found tells me to use a omv-extras menu, which i am not able to get.

Second Problem:

I heard its not really smart to run docker on my ssd, because its current format is ntfs. But i also heard i won't be able to run docker containers through my micro sd card (currently the OMV OS) because OMV locks it away from usage? Is that true?

Would it make sense then to format my ssd into ext4 (which i even never heard of, because i am completely new regarding linux) and store both my nas files and docker containers there?

I would be very thankful for any advices. I also thought about installing Pimox, then creating a vm for OMV and another one for docker. Would this be better? I literally spent half of the day trying to install docker through OMV without success...

Thanks in Advance!

In the wiki you have the vast majority of your questions answered.

I don't remember if those links mention anything about NTFS, but in any case I advise you to reserve NTFS for Windows. Use native linux file systems in linux and you will gain health.

Ok, so i have one more question. How long should it take my device to shutdown? I did it through the web interface but the system is still running, i cant access it anymore but when trying to open the web interface, its stuck on "loading".

That's not normal. If it does not turn off in a reasonable time depending on the power of the server, there is a problem.

It would be necessary to know more details to be able to help.

Hi Dawei ,

Please check links provided by chente - I've same problems moving my very old OMV5 system from SBC to new install.

The problem (issue??) is that most of (video-)guides are showing old version of docker installation where it was located within "extras" menu.

Install extras with one CLI command and go into Services > Compose where you will find "Porteiner-like" menu with all necessary parts.

As for SBC and OMV - as I've mentioned I used my old OMV5 on SBC with only 2GB ram (RockPi 4) - first with SD card only (later with eMMC + USB3 to SATA SSD + NVME SSD on HAT). I have not run into any issues with docker and system on SD card. I've used rather simple containers like Pi-hole and Netdata etc. But not checked with OMV6 on SBC.

As for resources: 8GB should be plenty for OMV 6 and docker containers - right now my system is running on 8GB "mini-pc" and 6 containers (with the most memory consuming Omada-controller) is using all together approx 2.5GB (while CPU is on 3-5% most of the time). Rpi4 with 8GB should be OK.

In case you are planning to use only one SSD on USB3 port you may run system/OMV on USB3 stick - I'm using RPi4 this way (for other system) and have had no issues for about 1 year. This way you may avoid SD card corruption since this type of memory is not the best for long usage as "hdd". In case you have to use SD card for system you may try to install Dietpi first (light version) and install OMV on top of it. Dietpi (based on Debian) got some features for SD cards (as far as I remember it is using RAM for most "current" read-write processes to extend SD card lifetime).

NTFS - no reason to keep it on 1TB unless you are planning to connect this drive back to W10/11. It is possible to use it this way but no perfect solution.

Turning off system on Raspberry:

- please remember that web interface is showing "last known stage" so it is/may trying to connect anyway;

- all devices connected to RPi are still powered - so (for NAS) it is good to either use USB cable with switch or power-supply HAT to shut down power in all devices (and network) when RPi shut down system;

- otherwise there is no really good signal you RPi is shut-down - you may ssh to RPi and check

And last-not-least - using just one SSD as NAS you may consider to use server Debian (no GUI) on USB stick (like Dietpi) + SSD-SATA drive with SAMBA share + Docker with Portainer (if needed). I have some devices running happily with a such setup - e.g. running on PiNano with 1GB RAM with SAMBA shares and Docker for Pihole etc.

You should have no problem running OMV on a PI4 with 8GB of RAM, I personally don't like them but many people do it without problems.

Just follow this document (make sure you use a 64-bit image) and then format that SSD to EXT4. https://wiki.omv-extras.org/do…omv6:raspberry_pi_install

Can somebody help me?

I cant manage to format my ntfs ssd into ext4.

I wiped it at first through omv web gui. I created a new ext4 filesystem then. After that, when mounting it, i get this error when applying the changes:

The Following modules will be updated:

- collectd

- fstab

- monit

- quota

500 - Internal Server Error

There is no description how to format it to EXT4 as it seems.

You can see that here. https://wiki.omv-extras.org/doku.php?id=omv6:new_user_guide

There is a lot of information available on the wiki on many different topics. Browse a little, you can find useful documents for you.
