creating share - cant select device

1st Official Post

    when creating a share, in the webUI i cannot select a device, as the list is empty


    OMV 5 (new build), Pi 4, jmicron 4disk sata controller

    finally got all disks seen by OMV, but couldn't create the RAID un the webUI, so i did that in Raspian using mdadm.

    i didnt go back to check the ui, and proceeded to create the filesystem from the shell and updated fstab.


    I include all of that because im wondering if that is the reason i cannot device?

    please let me know if this is a common issue i wasnt able to find when searching, or more logs/screenshots, etc would be needed to get more info

    Creating filesystems (formatting) in the shell does not populate the areas within OMV required to have those filesystems appear in the WebGUI drop-down lists for selection.


    Manual edits to fstab can also be problematic if later changes to the system force a rewrite of that file - your manually made changes can be lost unless properly delimited.

    A backup strategy is worthless unless you have a verified to work by testing restore strategy.

    Filesystems mounted manually are not usable in OMV. Filesystems have to be mounted from the GUI of OMV in order to be usable.

    Creation of RAID is disabled for USB devices for a reason. Many users had issues and even lost their data.

    So, strong suggestion: do not use RAID. There are better options like rsync.

    ok thanks, i had a feeling it might have been that, i will revisit my setup and decide what i might do here.

    I may keep the USB current jmicron controller, but im am aware of the potential risks.

    yea that was one of the things i was thinking about.. maybe ways to get some speed improvements from multiple disks. i have a couple external USB disks (4tb, 8tb and 10tb) that i might be able to use the rsync with for backup purposes. Are you talking about something that would actually be used in place of RAID?


    i have 4x 2TB 5400RPM rust disk, this is just for home storage. most of my stuff is currently on one the 3 external drives i have now, and anything that is of any real importance is also backed up using Acronis to their cloud storage as well. so i am doing multiple things to manage data loss. Another thing im interested in, is ways of using OMV's container services and plugins. im doing a lot of that already on a few other Pi's so im just looking at this to explore new self hosted options.

    Right. I used to have RAID1. But now I switched to individual disks. One disk is my main disk. The other disk is a backup disk. I run rsnapshot to create snapshots of my main disk to the backup disk. With rsnapshot you have the possibility to go back in time. So you can restore files as they were one day, one week, one month or one year ago. Depending on your setup.

    Also deleted files can be restored easily. Try that with RAID after data are synced ;)

    If the main disk gets encrypted only the snapshots created after that will be encrypted, but not the ones before.

    ok thanks, maybe i will setup a raid1 and then do an rsync over the network to one of the two disks that are part of my WDMyCloud device.


    I have never looked at it for ARM before, but can something similar be done with BTRfs? or so you have the same issues that you do with ZFS where you dont have the memory or CPU to deal with that type filesystem
