Request: guide for NAS OMV setup ROCK 5 ITX

#1

Hello,

I just got the new Rock 5 ITX board and would like to create a RAID Nas setup (using Openmediavault OMV). The documentation on Radxa’s website is very sparse, so I wanted to suggest collecting informaton in this thread, as I believe most people would like to use a setuplike this.

I installed the recommened OS image (https://docs.radxa.com/en/rock5/rock5itx/getting-started/install-os) but this is only Debian Version 11 and OMV requires 12 (https://docs.openmediavault.org/en/latest/releases.html)

Booting from ROOBI OS setting a custom OS download link (from Armbian for instance or local file server) did not work for me.

has anyone tried using the armbian image (https://www.armbian.com/radxa-rock-5-itx/) yet?

Press maskrom button to enter maskrom mode and flash armbian to emmc.

Same situation here. I managed to install the ubuntu by Joshua Riek on my nvme drive, but when I tried to install armbian there, it just started roobi OS from the emmc

I successfully installed latest Armbian to SD Card.
followed this guide to install OMV.
Power draw with SFX (85+) 350 watt power supply.

  • operational + 2x HDDS: ~ 25 watt
  • idle + 2x HDDS spindown: ~ 14 watt
  • operational + 2x SSD: ~ 17 Watt
  • idle + 2x SSD: ~ 12 watt

I created a Raid using the OMV md plugin but struggling to add that device (md0) to a LVM volume group (device not available to select, single drive can be). will investigate further

here some transfer speed tests with two SSDs and md0 as Raid1
unfortunately I cannot replicate the md0 speeds anymore, now tops out at 445MB/s. not sure what changed…

sudo hdparm -Tt /dev/md0

/dev/md0:

@rock-5-itx:~$ sudo hdparm -Tt /dev/md0
