Why USB disks are not shown in a RAID configuration option?

tetxi · Sep 16th 2020

Hi I've installed OMV in a raspberry PI with an Geekworm Raspberry Pi 4 NAS Dual SATA, X829 card, with two 2,5 hdd.

This Geekworm card is connected to the raspberry pi through the USB port.

Why can't I create a raid volume? The two discs don't appear on the available disks to create the RAID 1 volume I want to create.

Is there any option I forgot to apply?

Thanks.

The ability of using USB connected disks in a RAID in the OMV GUI was deprecated due to the practice causing too many problems.

It may still be possible to set this up by hand in the shell, bit I do not know for sure.

You have to create such RAIDs manually via CLI because we experienced too much data loss of users that used a RAID on USB.

raid on usb is terrible idea. Use rsync if you want a mirror of the other drive.
