Hi All,

I am new to the UnRaid OS. I installed the Community Addon and this was followed by installing the Unassigned Devices app.

 

I have two Samsung optical drives.  Each one is connected directly to the motherboard SATA ports.  When I insert a 4.36GB DVD disk into the optical drive tray and close it my Unassigned Devices app does not recognize the data on the 4.36GB DVD disk.  It's as though the optical drive is invisible to my Unassigned Devices app.

 

Can someone please confirm to me if the Unassigned Devices app is designed to support Optical Drives?  Currently, on my system it seems Unassigned Devices only recognizes a Thumb Drive Stick or a MyBook external hard drive if either one is connected to the USB 3.0 port.

 

I would be very grateful  if anybody in the community could give me some advice on how I can get my Unassigned Devices app to recognize my Samsung Optical drive connected to my motherboard SATA port.  Thank you for your time.

UD does not support optical drives.  You can mount the drive in a VM or Docker depending on your use case, or create an iso file from the DVD and mount that with UD.

Dlandon,

Thank you for your post.  Just as a hypothetical idea. What if I buy a portable optical drive that connects via a USB 3.0 male connector to the female USB 3.0 port on my UnRaid NAS, will Unassigned Devices work with such a USB 3.0 connection? My hunch is UD might look at the portable optical drive as if it were an external hard drive or thumb drive connected to the USB 3.0 port.

 

You mention dockers. Could you please name a docker app that supports an Optical Drive ?   As for virtual machines, that is my last option because it seems to be the most complicated one.

UD specifically ignores optical drives, no matter how they are connected to Unraid.

It's very easy.  Look at this:

 

Hi folks

When I swap over external backup HDD drives and I click the UNMOUNT button on the main tab, Unraid doesn't always unmount said drive correctly and, while the system still seems to work without issue, I get multiple (2-4/minute) errors in the syslog (EXT4-fs error (device sda1): ext4_find_entry:1455: inode #2: comm pool-16-thread-: reading directory lblock 0), which rapidly fills up; this is probably because the backup docker is still continuously trying to access the disk. Running the umount command in terminal fixes this, but I really would like a fix for this. Can anyone suggest anything?

Are you unmounting the drive before you remove it?  You can't remove the drive until it is successfully unmounted.

 

Post diagnostics.

Yes, I unmount by pressing the UNMOUNT button in the main page of Unraid. It's a bit hit and miss tbh, as it sometimes unmounts correctly and other times not

It doesn't appear to be related solely to unmounting of the disk.  I recommend the following:

• Remove the preclear plugin.
• Set the drive in question to not automount.
• Remove the drive in question.  USB drives should be unmounted and removed from the system when you reboot.
• Reboot the server.
• Plug the USB disk back in and mount it manually.
• Check the log for errors before unmounting it.

I suspect that the drive has some issues.  Post diagnostics again if the log has errors.

 

Why are you using EXT4 on the disk?

Hey lovely community,

i installed 'Unassigned Devices' but my storage doesn't mount automatically.
i tried it with fstab, but fstab delete after every reboot.

and under assigned devices isn't found there

so what is the best way ?

You have put your UD devices in the pool.  Stop the array and remove them from the pool.  You will then see them in the Unassigned Devices.

thank you, i stopped the array, did a new configuration (via tools).

 

if i use lsblk, my storage isn't still mounted.

Click the 'Mount' button on the UD disk.

The disk has no file system.  You'll need to format it.  You'll need to install the Unassigned Devices plus plugin to format it.

I've been using the plugin and it works very well.

 

I have 6 disks connected as UD. 3 NVME and 1 internal disk connect well and can be mounted.

I'd also like to connect one disk via USB. Unfortunately, this does not work and the "mount" button is greyed out. It used to work before, but stopped some days ago. I connected the disk to a notebook to eliminate a disk error. The notebook can identify the disk in the USB enclosure without problem.

 

Below info from the disk log information:

Log snippets are not very useful in troubleshooting problems.  Please post diagnostics for better support.

• Set the drive in question to not automount. All UD disks showing as Automount on when hovering over settings button, but when clicking on button, it shows as off. It doesn't matter if the setting is set to off or on, the disk mounts automatically

Why are you using EXT4 on the disk? No particular reason, it was just convenient. Would I be better off using another fs, disks are used for backup.

Go to the settings and then turn on and back off the automount.  That should clear it up.

Sorry, I should've been clearer. I did that already and the automount is showing as off in the settings, but on when I hover the mouse over it. The drive automounts regardless of the position in settings.

Delete the /flash/config/plugins/unassigned.disks/unassigned.devices.cfg file, then click on the 'Refresh Disks and Configuration" icon (double arrows in the upper right) and see if it doesn't clear up the automount.

I just looked through the diagnostics and it appears you have assigned USB disks to the array.  If that's true, that's not a good idea.  I suspect you are also using external drive bays.  That might also be a problem.

That seems to have sorted it. Hopefully this will resolve the issue of the ext drives not unmounting when they should; time will tell over the over the next couple of weeks when I do the backup disk swap out.  Thanks for your assistance and persistence 🙂
