Looks like the destination folder could not be empty. Try to clear it up for the mount point. Another thing, looks like you're using a pool filesystem, try to create the share in a branch disk not the pool. Try this last thing if clearing the folder doesn't help.

Hi, subzero79..Thanks for your answer...

Soo ... everything now again reconfigured, with the same resultsThe error message states, and I agree with you that I mount on my mhddfs pool.
But that is not so. My mount point is an empty and only hard drive with a single empty shared folder.the UUID is c9c36eb8-334c-4d7c-bc24-7be9140274a8.

Here my filesystems config:

Here my shared folders config:

the same error as above. I can see that again shows the mount point on Mhddfs pool.
Why?

Thank you for assistance

subzero79 · 21. September 2015

In the beginning it was complaining of mhdfs because I saw fuse. Does it say the same error now that your trying to mount to a single folder in single hdd or is a different error ?

mixmaster · 21. September 2015

Hi,
@subzero79..Thanks for your answer...

ohh..ich see that my answer has overlapped with yours.
Sorry for that.

it is the same error ... see above

Code

mhddfs: mount to: /media/c4e31f03-6327-4e23-86bb-871a1df07914

mhddfs: mount to: /media/c4e31f03-6327-4e23-86bb-871a1df07914 ---> Mhddfs pool

Thank you for assistance

subzero79 · 21. September 2015

Can you please not use the pool, use a member disk directly.

Create a share in one the filesystems that are member of the pool and use that one to mount the remote nfs

subzero79 · 21. September 2015

And don't use it in samba yet....let's check if it mounts first.

I don't understand? I do have an own empty harddrive. Not a pool.

Zitat

yes ... it works.

But only once, and now I can no longer delete the share.
The same error message.

Error above

Have now all want to clear, and the Mhddfs pool.
Got a message saying that the pool is in use.
All hard disks I had removed.
Now I still have the pool and get it not deleted from the file system.

Thank you for assistance

subzero79 · 21. September 2015

When you want to disassemble the pool you need to delete all shares connected to the pool from services (samba for example).

next to shared folders there is a tab that displays what service is using what share. Go to their respective service and delete the shares.

after that you can delete the sharrd folders in the shared folder section, be careful deleting because if you press the wrong button you can delete data.

finally with no shared folders from the pool you can delete the mhdfs fs.

Hi,@subzero79..Thanks for your answer...

Right ... I know.

No matter if i use a branch or a pool im always getting this error when im trying to create a smb share. (with drives in a pool share or a pool share)

seems that its currently not possible to use remote-fs plugin with a pool or drives (branches/leafs) in the pool.

my setup:
https://dl.dropboxusercontent.com/u/13344648/setup.PNG
https://dl.dropboxusercontent.com/u/13344648/setup2.PNG

Createing share-folder "backup_buffalo" in d6 to use it with remote-fs plugin. (d6 is member of poolshare)

error:
https://dl.dropboxusercontent.com/u/13344648/error.PNG

you cannot pass the error without to rollback witch deletes remote-fs entry and shared-folder from webui..
but:
-fstab entry created
-smb share is still successfully mounted to folder

mhh now i have to remove a drive from the pool to use remote-fs plugin? or should i mount cifs manually in fstab to poolshare?

whats the best option?

regards
firsttris

It must your setup on the remote box or omv. I have no problem using an aufs pool with a remote samba share. I guess I could add the option for non-empty but you really should have a dedicated, empty shared folder. Just make another one inside the pool.

And are you really trying to mount a samba share over the internet??? Please DON'T! Samba is not made for the internet.

firsttris · 11. Dezember 2015

hello,

not over the internet local area network. i use to often the word remote - sorry. (my fault).

i think this problem or lets say "warning" is cause by FUSE filesystem.

First i was using mhddfs now im using mergeFS.

remote-fs smb on mergeFs Poolshare (error): https://dl.dropboxusercontent.com/u/13344648/mergeFs.PNG
remote-fs ftp on single disk not in any poolshare (error): https://dl.dropboxusercontent.com/u/13344648/d1.PNG

fstab:
https://dl.dropboxusercontent.com/u/13344648/fstab

root@tvserv:/media/other# mount -a
fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the 'nonempty' mount option
fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the 'nonempty' mount option

on 2 different omv installs with FUSE filesystem (poolshare) i see this issue, i have another without FUSE filesystem in fstab and i dont have this issue in remote-fs plugin

ryecoaaron · 11. Dezember 2015

I didn't get internet from the word remote. I got it from the screenshot where the ip address started with 20.x.x.x. That isn't a local IP address.

You need to create a new shared folder using a new, empty folder. Otherwise, you need to add nonempty to the options in fstab. I really don't like mounting filesystems with nonempty because you don't know which filesystem the files are on and it may cause issues.

firsttris · 11. Dezember 2015

This LAN uses historically an IP range in 20.x.x.x i have no clue which specialist invented this

but i have left it like this because there are so many systems and clients with fixed adresses.. and for now i have no issue with any device in this ip-range.

how do they say: never change a running system.

But back to topic..

thats what i did - new freshly created empty shared folders, which i specially created to use as mountpoint with cifs/smb

ryecoaaron · 11. Dezember 2015

Is the shared folder the root of the drive?

firsttris · 11. Dezember 2015

yes the shared folder is in root of drive "d1"

ryecoaaron · 11. Dezember 2015

That is the problem. While you think it is empty, the lost&found directory always exists in the root of the drive. So, that folder will never be empty.

firsttris · 11. Dezember 2015

sure?
https://dl.dropboxusercontent.com/u/13344648/empty.PNG
https://dl.dropboxusercontent.com/u/13344648/empty2.PNG

(thats still the same usecase from all the screenshots settings/setup I postet above)...
