SFTP plugin

I get an error when trying to add shares to SFTP.

I have not the knowledge to understand the error.

Also I first had an error saying "The user does not have read-only or read-write permission" i fixed that but the share is completely empty. So somehow the content of the share was deleted. I have a back up which i keep offline until al problems are fixed then i copy back and start making backups again.

I am running OMV 6. Clean install. LVM to mirror 2 HDD's for data and 1 SSD for docker config.

Something weird are the /dev/dm-0 ... /dev/dm-5 they come from LVM but in the filesystem section in OMV gui /dev/dm-2 is listed as "FSData" where in the shared folders /dev/dm-5 is listed as "FSData". So the filesystem is not referenced according to the gui.

The LVM HDD's come from my raspberry to my new x86 device, so i just imported them.

Hope some can help! If i need to give more info just ask!

I do not like the weird things that are going on and I do not trust my NAS 100% at the moment.

The sftp plugin requires that you give permissions (NOT ACLs) to the shared folder at the OMV level. This has nothing to do with the files on the filesystem.

Does every user need these permissions or can I give the correct permissions to a group where they belong to?

My experience is that i need to set it correct for every user, which is in my case not a big deal ( 4 users), but a little weird.

Quote from ryecoaaron

OMV will not delete files. The content must have been deleted (or changed permissions?) by some other action you performed.

Probably. As i said not a big problem since i have a back up.

I would not use LVM for this. rsync is much better especially on an RPi (I know you moved away from it).

Let rsync sync to a second drive every night or couple of hours then, instead of the mirror? (Just interested)

If you click on the bell in the top right of the web interface, you can copy and paste the error instead of the screenshot which does not contain all of the error message.

Good to know!

I have a feeling it may be failing to bind mount to your LVM setup.

How can i check this? And or is this a big issue?

Thanks for helping! I know something but not everything.

Thanks for the info!

Quote from ryecoaaron

Compare the permissions you have given to the list of bind mounts in the output of mount

From the hole output of mount the only 3 interesting lines i have listed below. The permissions looks the same.

Is it possible you need to disable the SFTP plugin before changing the shares? when disabled i didn't got any errors.

Is this a problem?

Quote from ryecoaaron

If you disable the plugin, it does not create the shares. I'm not sure what change you are making.

Just adding or deleting shares from the SFTP plugin.

Is the shared folder you are using the root of the filesystem?

Output of lsblk.

It would be helpful to see the whole error from the bell in the top right.

I do not get any errors any more and i have the habit of clearing that section since the number stays next to the bell which i find distracting.

But i will try not to clear the bell section from now on.

I tried recreating the error, but i didn't get it any more.

Somehow happy its gone but on the other hand we do not know what caused it.

About the other thing, is that a problem? It is not related to SFPT I think

I also posted screenshots about it in post 8. Maybe i should have asked that in another thread.

Since I use this plugin a lot, I am quite sure it was something with the config you were trying to setup.

Probably

Quote from ryecoaaron

Seems like a visual problem

I expected something like that but wanted to be sure.

Thank you for helping!!
