If you are seeing unexplained disk or remote share activity, it may be due to cache dirs caching all folders.  For those of you using the Cache Dirs plugin, you need to specify folders to be included so UD mounted disks and shares do not get included automatically.  This can also apply to pool disks.  It's really the best practice to specify the included folders so you control what is actually being cached.

Major new release of UD: "Where are the switches?"  The "Pass Through", "Read Only", "Automount", and "Share" switches have been moved to a new Edit Settings dialog.  This is also where the script is modified.  This saves some real estate on the UD page and keeps the page refresh smooth. A "Show Partitions" switch has been added to set showing all partitions by specific hard drive device and not generically as before.  The option to show all partitions has been removed from the UD

New release of UD.  The changes are: - Add ability to spin down a disk by sdX.  You don't have to spin down disks by name= any more.  This is still available for spinning down a disk from a User Script because you won't know the correct sdX as it changes on reboot. - Add the ability to detach a disk when a UD script is finished using 'rc.unassigned'.  This detaches the disk from Unraid and should provide a potentially safer way to remove a USB device.  Applies to USB disks only. -

There is a new feature in UD to help with plugins that need a mount point folder.  UD now creates a mount folder '/mnt/addons'.  This folder should be used to mount your plugin devices to prevent FCP warnings and keep your mounts separated from UD.  It is recommended you switch to this new folder for your addon and custom mounts.  You are welcome to leave the mounts at '/mnt/disks' or '/mnt/remotes'.  Things will still work, but if you request support for UD issues, you will be asked to remove t

It's that self healing feature I built into UD.  It just fixes itself.

New release of UD.  Changes: When changing the mount point (which is also the share name), the mount point is checked for a duplicate of a user share or another UD device.  Samba cannot handle

Hello forum...  This is a great plugin and i've been using it for years.  However, recently I've been having trouble keeping a specific share mounted using the SMB option, as it will unmount itself after some time.  All other SMB shares mounted work perfectly.  I see the unRAID syslog entry when the share is mounted, but no syslog entry when the share unmounts itself.   The UD log button to the right of my affected share shows no entries.  

 

I did see this in the guidance in the OP, but I dont see the same option in the most recent version of UD (2019.10.18):

 

"There is a log file available that will log any errors from running your script file.  It is located at /tmp/ and is by the serial number or label of your drive/SMB Mount point.  You can test your disk script in a window.  Click on the Identification (serial number) when the disk is mounted and you'll see a lightning bolt.  Click on the lightning bolt and a window will open and run your drive script.  You'll then see any errors in your script and can make changes to fix the errors."

 

I'd like assistance with this issue, but not quite sure which log(s) to provide.  Please assist if possible, thanks!

Is this an external USB drive? Sometimes they will put themselves to sleep due to inactivity.

 

Actually no!  I'm using UD in this case to mount a share from my 2nd unRAID NAS.  Specifically so I can backup my VM vdisks with the unraid-autovmbackup script.   I plug the UD mount point (/mnt/disks/TOWERII_backupshare) into the "backup_location" script variable.  But every 1-2 days the share keeps un-mounting. 

 

My primary request at this point is for assistance finding out how to run the script file for errors per the guidance in the OP.  I see this option next to the physical disks I have mounted with UD, but not for the SMB shares I have mounted.  I know i'm missing something simple here....

You won't see anything logged for a SMB share, just a physical disk.  Your remote share is probably going off-line.

 

Post your diagnostics.

Sure thing! I can grab diagnostics from the remote server as well, if needed.

Several issues:

 

This message occurs when you have left an open browser session when rebooting the server: 

Oct 24 18:41:59 Tower root: error: /plugins/unassigned.devices/UnassignedDevices.php: wrong csrf_token
### [PREVIOUS LINE REPEATED 41 TIMES] ###

Be sure to close all browser sessions when you reboot the server.

 

You need to look at these FCP warnings and fix them: 

Oct 24 18:47:00 Tower root: Fix Common Problems Version 2018.10.21
Oct 24 18:47:00 Tower root: Fix Common Problems: Warning: Share domains set to not use the cache, but files / folders exist on the cache drive

It looks like CIFS VFS is having a problem.  It also appears that you are unmounting and re-mounting the shares constantly manually.

 

Fix the FCP issues, reboot the server, mount the shares and then capture the diagnostics right after the shares disconnect.  Your constant mounting and unmounting the shares makes it hard for me to see what is happening.

Understood!  Thanks a bunch for helping on this.  FCP issues cleared, except for Driver Controller error.  I have the standard SUPERMICRO AOC-SASLP-MV8 raid controller recommended when I first built my system back in 2012.  I will follow up with diagnostics once the share disconnects.

ROFL! That would make sense! Why didn't I think of that? (No seriously?)

 

Nov 2 14:08:02 Maximus unassigned.devices: Share '//MEDIA-CENTRE/ChildrensTV$' contains a '$' character.#011It cannot be mounted.

Are hidden shares not mountable?

The '$' is not allowed in the share name.

It is possible to mount, but I believe the '$' character caused some issues in the share name with UD, so It is not allowed by UD.  I don't intend to make any changes to accommodate the '$' character.  Rename the share.

This is a shame. Thanks for the help though. I've got it working, but don't like the fact that the shares are now not only visible on my media server, but also on unraid too. I don't like shares "easily visible" it's just too easy for my 7/10/11 year olds to stumble across them.

Thanks.

In samba settings for a share, if your add: 

browseable = No

Then the share will not show up in windows Explorer.  Not sure if UD can make this happen, but that's the way to solve it.

Set the Settings->Unassigned Devices->SMB Security to 'Yes (Hidden)' and the Unraid shares will be hidden and not browseable.

Thanks. using these settings I can hide the Unraid shares like this, but the windows shares are still "browseable", but the windows shares are now visible.

 

Never mind. Really appreciate the help.

Linux really isn't something I'm familiar with.
