Suddenly nearly all Users gone after Shutdown

[sausagewaterson]

A wonderful good day my friends,

 

Yesterday I briefly shut down the Unraid server and unscrewed the feet on the housing.

 

When I booted the system up again, no network share was functional anywhere.

 

Then I saw this on the Dashboard:

Even after several reboots, the appropriate users no longer appeared.

 

I was able to recreate all users again.

The Unraid still knew all permissions of the other users..

 

Sadly, I can no longer delete this weirdo. I have changed his permissions. Had access on my "share"-share, which was set in public...

 

Now to the question:

1. how could I find out what happened?
2. is it possible to delete users created in Unraid via CLI?

 

Thanks in advance and have a good start into the new year.

Please post the diagnostics.

[sausagewaterson]

Thanks for your time.

There it is.

Nothing obvious that I can see, if you go to /boot/config/shares do you see that garbled backup share cfg?

 

Do you have a recent flash drive backup?

[sausagewaterson]

The last backup is a bit older, sadly.

 

root@Tower2:~# ls -alh /boot/config/shares/
total 152K
drwx------  2 root root 8.0K Sep  3 13:36 ./
drwx------ 11 root root 8.0K Dec 31 12:09 ../
-rw-------  1 root root  436 Dec 30 21:40 Share.cfg
...

 

root@Tower2:~# cat /boot/config/shares/Share.cfg
# Generated settings:

What you mean by garbled?

[JorgeB]

I meant for the backup share, so backup.cfg, do you only have that one starting with a b?

[sausagewaterson]

It's the only one starting with a b, yes.

-rw------- 1 root root 457 Mar 13  2022 /boot/config/shares/backup.cfg

Sorry, my bad, the problem was with users not shares, try this:

 

https://wiki.unraid.net/Manual/Troubleshooting#Lost_root_Password

 

Note that you'll need to recreate the users after doing that.

[sausagewaterson]

Root is and was working.

Recreated the users already.

Cant delete the weird user in picture 4.

 

When i hit delete nothings happens.

 

Therefore the question, if you could delete an Unraid-User through CLI.

Deleting those files will delete all the users, technically you only need to delete one, but not sure which one stores the users, I believe it's config/passwd if you want to try just that one.

[sausagewaterson]

Iam still not talking about files.

A User, that randomly - out of nothing - appeared.

 

Which sadly cant be removed through the Users Tab within Unraid.

 

So it is not possible to delete a Unraid User other the with Unraid it self?

 

 

[JorgeB]

Again, if you delete those files it should delete all the users.
