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.
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:
