Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

Look into the servers smb log, (not the system journal about broken service invocation) but I guess a symlink link to / along the "follow symlinks = yes" policy is just enough to pull the breaks.

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

All logs under /var/log/samba are empty except smb.log and nmb.log which show no errors.
Is there a different log directory?

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

Raise the log level. Remove the symlink (and restart smb) - it should absofuckinglutely not be there.

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

To what should I change my log level? this is the current output:

kernel.printk = 1       4       1       4

As for the symlink, I cant remove it:

rm: refusing to remove '.' or '..' directory: skipping '../'

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

Symlinks look like this "lrwxrwxrwx"
I'd suggest post the damn thing with all filenames "ls -lah /Red-Vol"

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

In that case, no symlinks. These are all directories:

ls -lah /Red-Vol/
total 20K
drwxrwxr-x  1 shmick shmick   94 Jun  9 12:05  .
drwxr-xr-x 22 root   root   4.0K Jun  8 12:15  ..
drwx------  1 shmick shmick   46 Jun  9 12:05  .Trash-1000
drwxr-xr-x  1 shmick shmick  144 Jun  3 18:41  Backups
drwxr-xr-x  1 shmick shmick   16 Jun  3 19:01  Torrents

drwxr-xr-x  1 shmick shmick  212 Jun  9 12:05  btrfs

I don't think that is the issue, though - these are all inside 'Red-Vol'. I can't access 'Red-Vol' itself.

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

Put "log level = 3" in [global] and restart smb, nmb.  Try again to access the share and paste the new logs here

I've tried this before, but trying again now it shows new output:

It still isn't working though.

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

try log level = 10, you'll probably need to use a pastebin service to post the logs

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

Hi,
I've just tried recreating the share on a live Arch enviroment, and a Clear Linux environment, and the error persists. Whatever the error is, it's within the drive.
Any idea on what it could be? I'm quite clueless...

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

I would try getting rid of  ".Trash-1000" folder

And also what is that btrfs folder?

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

I've tried getting rid of the Trash-1000. It reappears after being deleted almost immediately.
The btrfs folder is a simple file backup.
I'll try creating a copy on ZFS or XFS and see if the problem persists.
No idea what else can cause this...

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

A stab in the dark...
remove these from your conf

        dns proxy = No
        unix extensions = No
        wide links = Yes

Edit: as a sanity check can you mount your share manually? https://wiki.archlinux.org/index.php/sa … l_mounting

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

Same result.
Mounting the share manually also throws an 'access denied':

ls: reading directory '/mnt/': Permission denied

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

Do you have the level 10 log?

So, it fails on various server OS and also sharing from other FS.
Is there a firewall in the network?

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

Have you enabled apparmor?

I just had this same problem and the cause was, me enabling apparmor for snaps. Fix was this

edit + it does show up in syslog

Re: SMB share suddenly denies access - need help troubleshooting [SOLVED]

That was it! the share is working again.
I enabled apparmor when first installing (about a year back) and forgot it's even there.
Thank you all for taking the time to help!
