Remote Mount File System Issues

McDuff · 26. September 2017

I can't seem to find a solution to this on the forum.

I wanted to use Remote Mount to mount a folder on my windows box, but after trying several different things I couldn't get it to work and it kept saying "connection timeout." I decided to leave it for now and use Syncthing instead, but when I went to delete the share I got this error.

Code

Failed to execute XPath query '//system/fstab/mntent[uuid='8f787116-ea53-41a2-bf2e-7f2b9446baca']'.

When I go into the file systems tab it throws the same error. When I ask for more details it gives me this.

Code

Error #0:

I see that some people have had issues booting after similar sounding problems. Do I need to manually edit Fstab or something?

I think I've solved the issue by uninstalling the plugin, but it would be nice to have some advice as to what caused that and to see if I can get it to work.

Do I need to manually edit Fstab or something?

NO. You can specify all the options in the plugin. It is hard to help without seeing the settings/details about the remote mount.

McDuff · 26. September 2017

I just kept the defaults.

I just kept the defaults.

There are no defaults for the server, share name, etc. Lots of people enter these fields incorrectly.

People also have incorrect permissions on the target server which the plugin cannot fix.

There are too many details missing to help. I don't know what kind of system OMV is installed on. I don't even know what kind of share you are trying to connect to.

I use this plugin myself. I know nfs and samba are working for me. So, I doubt there is a plugin code problem.

McDuff · 26. September 2017

The share is hosted on a windows 10 machine and set up to allow guest access.

There was no documentation for syntax for the share names, so I tried a whole bunch of things. I tried the server name by itself, and with preceding slashes. I tried changing the name of the share so it didn't have spaces in it. I tried logging in as a guest and as my windows user. I tried putting the share name in full (//Server/Sharename) and without, changing to all uppercase, changing to all lowercase. I couldn't find any examples of what a "correct" configuration actually looked like on line and I ran out of permutations I thought were likely.

I tried the server name by itself

That is what it should be. That doesn't mean your OMV server is resolving the windows name though. As for documentation, what else do you want? For the server name, it tells you exactly what should be there - FQDN, hostname, or IP address. It doesn't say anything about slashes (since that is a windows explorer thing). The sharename says use the sharename only or export path for nfs. I don't know how to describe that any clearer.

Correct on my setup may not be correct on your setup. Attached are two pics of working configs. It sounds like you probably already tried these configs though. Which would tell me you need to change something on the Windows side. Is it a Win10 Pro machine?
