OMV or Raspberry Pi 4b with 4 GB RAM

Robinson · May 7th 2023

Hello to All,

I am new here and new to NAS.

I have just bought a Raspberry Pi 4 b (with Retropie 4.8 image) and have learnt that I can have a centralized file server using OMV.

Is there perhaps an introduction to OMV for beginners like me?

I do not have a HDD yet but I am aiming at 4-6 TB. Can I install OMV before my target HDD is connected to Pi? Or is it better to first connect the external drive and then install OMV?

Is OMV 6 OK for Pi?

Thanks.

By the way, is there perhaps a list of recommended HDD's? Ad also, does anyone know if I need a separate active USB hub or can I connect my HDD directly to Pi?

Lots of people use raspberry to host OMV. It has its advantages and disadvantages, I'm not going to get into that discussion.

The precautions with a raspberry are fundamentally to be aware of possible power problems on the disks, so the answer is yes, a separate source for the disks is preferable. Unless there is only one disk and it is SSD.

You can install OMV without a disk, in fact it is recommended to do it that way and connect the disks later. Although without discs you won't be able to get much use out of it, but you can practice and learn.

There is no list of recommended drives, but I suggest you use a drive made specifically for NAS. They are somewhat more expensive than the others but there are reasons for this. And if it is CMR it will be better than SMR.

Welcome.

With its own power supply (it is essential to use the original power supply unit), the Raspi can supply a 2.5 inch hard drive and an SD card or a USB stick with power to some extent. If you hang more on the USB ports of the Raspi, undervoltage or inexplicable phenomena can occur. It is better to use a 3.5 inch hard drive in a Sata-USB3 housing with its own power supply. Not every Sata-USB3 adapter or not every USB3 hard drive housing (or the built-in converter chip) is compatible with the Raspi. In the German Raspi forum there is a list of compatible Sata-USB adapters (I would install the operating system (RasperryPi OS Light plus OMV on a good SD card and make backups of it from time to time with dd.

Thank you, both of you.

So before I buy an HDD I will install OMV to learn a bit.

First I thought of 3.5" WD Red HDD (CMR) with a USB-SATA converter. Or can I get a case for it?

Then I thought about a 2.5" USB HDD but they are probably not suitable for NAS, are they?

Can someone please recommend particular models to be used with Pi 4 and OMV?

mischka, can you copy and paste the list of compatible Sata-USB adapters or USB3 hard drive housings from that German forum?

Thanks.

BTW, what about Unitek Y-1039 adapter? Will it work fine with a HDD connected to Pi?

As for self-powered USB hubs, will UGREEN CM481 be OK?

If you can afford it, people often buy boxes of this type to connect to a raspberry. https://www.amazon.es/ICY-BOX-…s=electronics&sr=1-7&th=1

I'm not sure if that particular model is suitable, I don't use raspberry as a server.

You can look at the assembly forum section. My NAS Build

They have disabled All RAID, even Mirror using USB attached drives, so there is no point in installing it on a Rasbperry Pi.

And from where did you got that (wrong) information?

I used the box chente posted with RAID1 BTRFS for almost 2 years and OMV never complain or block anything.

OMV only blocks it on the GUI. Doesn't mean that you can't do it.

It is advised against do to the many issues it caused to many users, nopthing more.

Funny, I use my RPi with OMV on it as a backup to my primary NAS and it works great. Your view is very short sighted. You have posted this same comment in two threads now.

OK I have just ordered a 6 TB WD Red Plus with a self-powered housing to connect to RPi using USB.

For now it will be just one HDD, no RAID or mirroring.

I am just wondering if it is advisable to have several partitions or not necessarily. There will be 2-3 users and 5-6 different devices to back up on this HDD.

No need to partition. The GUI allows you to set separate resources with separate permissions for different users. Why do you think partitioning might be necessary?

Robinson · May 14th 2023

I just did not know.

It is probably naive for me to think that data on one partition could be copies to the other and be a bit safer in case of HDD failure.

mischka · May 15th 2023

If a hard disk fails, all partitions on that disk are gone. So duplicating the data to a second partition on the same disk is a pointless waste of space. A second hard drive is required to back up the data.

That isn't true. Disk failure is not the only thing you have to worry about. While I wouldn't use partitions (folders are good enough), you could share partition #1 or folder #1 to the network and borgbackup/rsnapshot to partition #2 or folder #2. If #2 is not shared to the network, there is little way it could be altered by a virus or other malicious things. If something bad happened to #1, you still have your backup on #2. Even if you accidentally deleted file(s), you would still be covered by #2.

Greetings, I have found this post from searching. I know it has been a long time but I would like to inquire about the items you purchased after your research and more importantly your experience so far. How has it been, any shortcomings and if you would change anything.
