DietPi-Software | OMV 3 - Unable to create Shared Folders

[LexiconCode]

Under "Shared Folders" you cannot select a Device since there are no options shown.

Hardware
Odroid C2

Configuration
Dietpi 142

Steps to reproduce

1. Install OMV 3
2. attach a USB hard drive (I've tried both setting up through Dietpi and mounting through is the OS) (formatted as ext4 )
3. log into open media vault
4. check "Physical Devices" - verify external hard drive and OS medium
5. Go to "Shared Folders" and try to add a folder.

@LexiconCode

Thanks, i'll take a look.

Yep, looks like anything to do with:
"Select a device"

Results in no options.

Only error in log is (doesn't look related):

root@DietPi:~# cat /var/log/nginx/openmediavault-webgui_error.log
2017/01/22 13:38:39 [error] 1243#0: *28 open() "/var/www/openmediavault/omv" failed (2: No such file or directory), client: 192.168.0.22, server: openmediavault-webgui, request: "GET /omv HTTP/1.1", host: "192.168.0.112"

Ok, looks like OMV scraping of /etc/fstab is not compatible with DietPi-Drive_manager or any manual USB drive additions.

OMV adds headers/blocks which (i'am assuming) OMV web interface and code, requires to work with:

# >>> [openmediavault]
UUID=45aa4dad-dfd2-492b-917f-11fb0ff3e29b /media/45aa4dad-dfd2-492b-917f-11fb0ff3e29b ext4 defaults,nofail,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,acl 0 2
# <<< [openmediavault]

Basically, if you want to use OMV's features, only use OMV features:

• dietpi-drive_manager, unmount drive and eject
• exit
• Plug drive back in
• OMV > Physical Disks > Wipe
• OMV > File Systems > Create
• OMV > File Systems > Mount
• OMV > Shared folders > Add

Drive is now available.

@LexiconCode if you can confirm above working, please let me know and i'll close this ticket.

First, I really like OVM.
But my experience is, you have to run it on performant hardware, like i386 platforms.
On SBC it will have weak performance and stability for a NAS system (hardware limitation).
And OVM is a "all-in-one" system, like a complete OS witch system configuration tools.
If you need something more, you have to install a OVM plugin, if where is one for it.

Like I write up here ( http://dietpi.com/phpbb/viewtopic.php?f=12&t=1040&p=4478#p4478 ) I personally think it's not a good idea to use DietPi on the same device with OMV.
And please read @Fourdee https://github.com/Fourdee/DietPi/issues/495#issuecomment-271571863 here.

Hardware

Yep, may need to drop this one from dietpi-software, can see it causing no end of incompatibility issues with DietPi (and manual user) configurations.

In the case here (https://github.com/Fourdee/DietPi/issues/721#issuecomment-274332945) manual mount entries to /etc/fstab are not fully supported/recognized by all OMV's plugins (eg: device dropdown list). Unless the whole process of formatting, creating FS, mounting is completed in OMV.

Yes, OVM on DietPi is not more as an early beta. We can test it, but ...

Yes, many incompatibility issues with DietPi configurations and error messages while installing and in the logs.
I have not a huge promise to get this fixed.

The web UI is clunky and slow. The huge draw for this type of software for me is the ability to configure nearly everything from the web user interface. Hopefully there is an alternative.

yes, a user has started to create one, see https://github.com/Fourdee/DietPi/issues/448#issuecomment-242536278

but he has decided to deleted all his work ... 👎

You can test if Webmin do what you are looking for, but I not a big fan to do this on DietPi.

Ok, added a notice to OMV online doc: http://dietpi.com/phpbb/viewtopic.php?f=8&t=5&p=4859#p4859

Will mark this as closed.

Thanks for looking into it. @Fourdee

@k-plan
I've considered using Webmin. I've decided against because of outstanding security concerns and I found it to be unreliable with setting configurations. In addition its plug-in system is atrocious and not well-maintained for ARM.

Anyway I will continue seeking alternatives but this does bring in question how any software like Webmin would interact with DietPi.

DietPi has various methods for installing software and then applying its configuration. Basically we need a web admin panel that's robust enough to handle DietPi use cases. If you guys think it's worth it I'll open a separate ticket to carry on this discussion.

Already have one open, and yes, all we need is a web interface for DietPi, would be a great addition.
