    hello everybody,

    I run an old dell server (t320) with a dell h310 raid card which i crossed flashed to IT mode.

    OMV runs as a virtual machine in proxmox. i passed through some disks to OMV but i did not do PCIe passthrough.

    so far i'm happy: backups to OMV seem fast enough and everything seems to be working smoothly except smart of course.

    i have read that on a virtualized freenas with disks passed in such a way scrubbing would do more harm than benefit because zfs is not talking to the controller directly, so i started to wonder if this could be the case with snapraid too, although i use ext4 and not zfs.

    So is it safe for snapraid to scrub on a passedthrough disk in a OMV Virtual Machine?

    Thanks in advance..

    thanks for your help.

    i'll give proxmox another go. i'll install it on the sdd then and i'll use 1 500 gb for Vms and Dockers and the other for their backup. I'll pass the two 3tb drives to OMV and see what happens.

    Since i'm still at the very beginning i'll give proxmox another go. what will be the benefits of passing the controller instead of the single drives? SMART monitoring?

    I have a perc h310 not flashed which can pass through drives as non raid. i was thinking of creating a hardware raid 1 array with the two 500gb drives for proxmox plus VMs and containers and pass through the two 3tb drives to OMV to take care of the nas side. this way i could still recover the data on the drives and reinstall proxmox and virtual machines ig somethong goes wrong. but it seems that i can not have different kinds of drives on the controller: either all as non raid or all raid ready.

    i know that flashing the controller is the recommended setup but i'm not really convinced to face the risk of bricking it...

    I don't know... OMV 4 would imstall without any issues. Proxmox (or athore virtualizing software) n was the first thing I thought. But I found it of difficult implementation.

    I guess I should pass through the hard disks to omv

    I was stuck on two things. First what would happen in case of losing the os disk. I did some testing and recovering the VMs is difficult

    Second I couldn't manage to get a fixed ip address for omv. On bare metal I can force the dhcp to assign it the same address.....


    i couldn't install OMV Iso; it hangs on detecting network connection. i had to go the debian minimal install first route.

    i installed and reinstalled OMV (and ubuntu; and proxmox and whatnot) many times, encountering difficulties that i had to solve sometimes creatively.

    I can connect to the server through a console via Idrac and is like being connected directly. the only problem is that this way my keyboard is not recognised properly so i cannot press some keys. the first time i sshed (is that a word?) the code needed to instal OMV through terminal everything seemed going fine untill the very end when it didn't recognise the last instruction (omv-confdbabmd populate) and the server crashed.

    so the first solution i had thought was to install via idrac (the console) debian with a desktop enviroment so i could copy/paste the code with the help of the browser. and it worked perfectly. but is adviced against the installation of OMV with a desktop enviroment. (although i read that someone use it for rdb).

    So i tried again via ssh and as expected at the very end error and crash. this time I rebooted and entered the last command on the console and it seems to have worked so i can get in OMV.

    Now i will follow some guides on how to configure it properly (techno dad videos look great). but before going all in i would like to share the thoughts of people more experienced if this is the right path for my needs (back up for data in other computers, home assistant for some automation, a minecraft server for the kids to play with their friends...) or should i follow another route....

    As I said i had to go the debian install route. Ssh at the very end (OMV-something populate) gave me an error. Couldn't follow the instructions on idrac because my keyboard layout is Italian and debian installer didn't recognise the keyboard properly.

    So I installed xfce so I could copy/paste the instructions. I liked the idea to have a DE so to access the file system more easily. but I know that is not recommended with OMV. Just wondering if for my case scenario would be better have debian with xfce without OMV...

    Thanks for your replies. I know that parity disk has to be as large as the larger. I read that I could setup the two 500 gb plus one of the 3tb and 1 3tb for parity. But to me doesn't sum up unless it stops backing up at some point.

    In reality I wanted to build a rig with an Intel j5005 and 16 gb of ram at most. But in the meantime I was reading about freenas... and zfs... and it's need of ram and that should have been ecc ram... So I bid over this dell t320 for joke and it turned out I won the auction (211 euros)...

    So what can you tell me? as far as I am concerned OMV will tick all the boxes. or should I go some other route maybe just plain debian with xfce? Clrearos?...

    Hello everybody I was finally able to install OMV on top of debian net install because for some reason OMV installer would hang on networking.

    Making a long story short I have bought an used dell t320 which I'll primarily use as a backup for data that will be stored on various pcs on my home lan.

    As it would be a pity to use a full blown server only as a NaS I spent the last couple of weeks studying and trying to figure the best configuration to accomplish the primary goal but being able to experiment and learn other things (pihole, home assistant, minecraft server) .

    I must admit is a tough and confusing job for a complete noob like me so bare with me. Please.

    I've tried proxmox but I'm not comfortable on virtualizing a Nas. I've tried debian with xfce which I find reassuring since it has a GUI but i think that OMV would be easier in many tasks storage related.

    I came to the conclusion that for my level of knowledge (low) OMV coupled with cockpit would give me a solid performance for my primary goal permitting me also, to tinker and learn new things via docker and VMs without risking too much. For my use case scenario is my reasoning sound or should I follow another path.

    I don't really need redundancy as most of the data would be in other disks too but I'm inclined to a setup with mergerfs+ snap raid (or even without mergerfs).

    I will have a 120 gb ssd as boot disk and another 4 disks (2 500gb and 2 3tb) but there is something I don't understand: how can 1 single parity disk protect an array of multiple disks that are more than double its size?

    What happens if the os disk or some other hardware fails? would I be able to reinstall OMV and recover all the data in the disks?

    Lastly, I have 48 gb of Ram do I really need 48 GB of swap (os disk is only 120bgb)?

    Thanks for you help

    Hello everyone. I fell in the rabbit hole and I'm lost....

    I was looking to replace my old netgear nas that died on me. Fortunately I mostly used the nas as a backup so I could recover 95% of my data but that's another story.

    Since I was burned by a ready made solution I was on the market to build my own nas. I wanted to build something small, efficient and possibly cheap. i was looking for a pentium silver or gold build but couldn't find a consumer motherboard that supported ecc ram.

    In the meantime I placed an offer (211 euros) for an used dell t320 which I didn't think I could win... But I did:):(:) so here I am.

    Unfortunately I've come across many problems or doubts that I'll try to explain.

    1st. Raid Controller - the raid controller in my setup is the dell h310. I understand that is recommended to flash it with an IT firmware so to disable the Raid Functionality. I'm not really keen to do that first of all I wouldn't know how to do it on the dell server. And secondly the controller Is deeply intertwined in the machines bios and I'm afraid it could effect the server's functionality. That said the controller can set up a raid array or can also set the disks as non raid. OMV 4 can see both configurations. For now I'm keen to pass to OMV the non raid disks and install the os on a thumb drive (I had problems installling on a 32 gb drive by it seems is because I have 48 gb of ram and I've read the solution).

    2nd) broadcom drivers. I can install omv4 without any problems (except to install it on a thumb drive) OMV 5 installation hangs on setting the lan. It seems the issue is due to the broadcom drivers (5720). I tried to put the omv4 drivers present in pool and firmware in the same folders of the OMV 5 installation with no success is there a way to solve the problem?

    3d)the server came with 2 500 gb drives. Since I would like to use some VMs and containers and a plex server (and, if possible a minecraft server) i was thinking a possible alternative strategy would be to make through bios 2 virtual disks set in raid 1. one (120 gb) to install OMV (4 or 5) and the remaining space for the VM disks. Other physical drives for data storage could be attached as non raid.

    4th) if I couldn't install OMV5 but Only OMV5 would i miss something useful?

    5th) for my use case scenario would it be better to install proxmox (which installs flawlessly) and virtualize OMV?

    Sorry for the noobs questions. I did my homework but can't go further.
