Lost Permissions on SMB share

[eseanq]

TrueNAS-12.0-U7
I was in the process of setting up a jail for Plex, and in doing so somehow the permissions on one of my datasets on a Pool got messed up.

When mounting to the share in macOS using the username/password created in the TrueNAS GUI, it shows 0 files, yet the available space shows that about 80% is used. The "bad" dataset is HD-Movies.

If I do a ls -l within shell it yields:

Code:

root@FreeNAS-Server[~]# ls -l /mnt/
total 223
drwxr-xr-x    4 root    wheel    4 Feb 26  2021 Data
drwxrwxr-x    3 eseanq  media    3 May 23 07:19 HD-Movies
drwxrwxr-x   6 eseanq  media    8 Oct 19  2020 HD-Movies_2
-rw-r--r--    1 root    wheel    5 Dec  8 13:20 md_size
drwxrwxr-x+   7 eseanq  staff    7 Oct 23  2020 Pool1
drwxrwxr-x+ 319 eseanq  media  322 May 22 15:08 TV-Shows

How can I reset(?) the permissions on the dataset so I can once again see my files?

find /mnt/HD-Movies -exec setfacl -b {} \; will whack the ACLs from HD-Movies and all contents. chmod -R u+rw,g+rw,o+r /mnt/HD-Movies; chown -R eseanq:media HD-Movies will set a reasonable permission set to HD-Movies and its contents.

 

[eseanq]

Hmm. Still not seeing anything, though I do have permissions to read/write.

 

[eseanq]

Not sure if it's a good thing or bad, but while poking around & noticed that if I try to set up a new SMB share using that dataset, I can't even see subfolders thru TrueNAS GUI that were made on the share

 

[Samuel Tai]

What do you see in the Shell under that directory?

 

[eseanq]

Code:

root@FreeNAS-Server[~]# ls -l /mnt/HD-Movies
total 217
drwxrwxrwx+ 2 eseanq  media  2 May 23 11:55 HD-Movies
root@FreeNAS-Server[~]# ls -l /mnt/HD-Movies/HD-Movies
total 0
root@FreeNAS-Server[~]#

 

[Samuel Tai]

What does ls -al /mnt/HD-Movies show?

 

[eseanq]

Code:

root@FreeNAS-Server[~]# ls -al /mnt/HD-Movies
total 217
drwxrwxr--  3 eseanq  media    3 May 23 14:13 .
drwxr-xr-x  7 root    wheel  384 May 23 12:53 ..
drwxrwxrwx  2 eseanq  media    2 May 23 11:55 HD-Movies

 

[Samuel Tai]

Hmm. Do you have a dataset named HD-Movies inside /mnt/HD-Movies? Was this intentional?

 

[eseanq]

Yeah, the pool is HD-Movies, the dataset is also HD-Movies. I didn't realize it would cause problems..

 

[Samuel Tai]

OK, then try find /mnt/HD-Movies/HD-Movies -exec setfacl -b {} \; to whack the ACLs from the HD-Movies dataset underneath the pool and all contents; and chmod -R u+rw,g+rw,o+r /mnt/HD-Movies/HD-Movies; chown -R eseanq:media /mnt/HD-Movies/HD-Movies to set reasonable permissions.

 

[eseanq]

As of right now I'm still seeing 0 files in Finder, and ls inside of /mnt/HD-Movies/HD-Movies yields zero results

 

[Samuel Tai]

OK, then what probably happened is you might've deleted the contents of that dataset. Do you have any snapshots of that dataset to which you could revert?

 

[eseanq]

That's kinda what I feared may have happened. It's just odd that in the web GUI under Storage/Pools it list the pool and dataset as being 14.04 TiB used and 3.96 TiB available.

But for snapshots, unfortunately I don't have one prior to having this all happen

 

[Samuel Tai]

Is there a .recycle directory under /mnt/HD-Movies/HD-Movies? You'll need to ls -al /mnt/HD-Movies/HD-Movies to see it.

 

[eseanq]

Code:

root@FreeNAS-Server[~]# ls -al /mnt/HD-Movies/HD-Movies
total 217
drwxrwxr-x  2 eseanq  media  2 May 23 11:55 .
drwxrwxr--  3 eseanq  media  3 May 23 14:13 ..
root@FreeNAS-Server[~]# 

 

[Samuel Tai]

What does zfs get all HD-Movies/HD-Movies show?

 

[eseanq]

Code:

root@FreeNAS-Server[/]# zfs get all HD-Movies/HD-Movies

OK, it does appear you have snapshots of this dataset you could use to recover your data. The usedbysnapshots property shows 14TB. Do you see snapshots available under Storage->Snapshots?

 

[eseanq]

Yeah, I did a manual snapshot yesterday at ~1200 for HD-Movies/HD-Movies
