Mounting SMB share CIFS - permission denied

TrueNAS General
21

Ooh interesting. So I just checked the dataset > permissions on the folder and group users have read and write permissions.

the user I added is in the group folder

22

i posted it in the OP but will reshare here and yes i followed that guide

//IP Address/books /mnt/books cifs credentials=/home/USERNAME/.smbcredentials 0 0

the folder path in truenas as displayed under Path in the data set is

data/fs1/books

double checked and all users on the group users have read and execute access. the user in question is in the users group.

and just to reiterate i manually made the directory on the ubuntu machine already

Can you post the format of the fstab entry? You can change/hide sensitive info if desired, but > keep the syntax and format in place.

I posted it above.

What are the permissions and ownership for the file /home/USERNAME/.smbcredentials ?

Does the password contain any special characters?

It does actually, is that incompatible? that did cross my mind.

Is the share name really “books”, and the path on the server is /mnt/data/fs1/books ?

it’s not books, name is private but the rest of the path is 100% accurate, copied and pasted directly from truenas expect truenas doesn’t use mnt in the data set path like you did above

Can you temporarily mount the share without fstab?

mkdir /mnt/smbtest
mount -t cifs -o ro,file_mode=0444,dir_mode=0555,uid=1000,gid=1000,username=truenasuser //192.168.0.100/share /mnt/smbtest

EDIT: Change the values accordingly, such as the IP address.

I try now

no clue why my text is big here lol

Yes it does. TrueNAS imports pools with -R /mnt, so that all paths start with /mnt/<poolname>.

Unless you circumvented the web UI when importing this pool.

Can you confirm the permissions for this file?

If the manual mount command doesn’t work, you can try again, but this time change the TrueNAS user’s password to something simple like password1234. This way we can rule out special characters.

I just used the GUI, and have no knowledge of the truenas shell.

so were on the same page im using the latest truenas community and when clicking datasets > datasets name > books > dataset details the Path shows exactly Path: data/fs1/books in that exact format. There is not mnt in the path and i still can’t share screenshots to prove my innocence here.

my bad forgot to mention above, my .smbcredentials file permission are 600 just like that article stated.

changed it what you wrote. still producing the same error as in my OP

That’s the dataset layout.

For the actual filesystem path (folders), it is /mnt/data/fs1/books/, which is also what the SMB shares are concerned with.

Did you try it with a simple password, like password1234? You’ll have to make your TrueNAS user’s password temporarily password1234.

are you saying that I should try with //192.168.1.200/mnt/data/fs1/books/ instead?

yes that’s what i did, i changed the password in truenas and made it password1234 then placed that in the command you shared.

That produced the same error as in my OP

I’m a dummy. I missed the other part of your post.

Please don’t ban my account, TrueNAS Forum Owner. I’ll try better. :pray:

You’re on Ubuntu…

Can you double check:

apt install cifs-utils
32

you want me to reinstall it?

34

I had an incident on Pop!_OS where an update removed cifs-utils without me noticing it. My SMB shares stopped working.

I had to manually reinstall the package.

Doesn’t hurt to try.

35 
cifs-utils is already the newest version (2:7.0-2build1).
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

im sure this is user error on my end regarding truenas. im just have a gut feeling since I’m not new to linux but just truenas

37

No. The first way was correct:
//192.168.1.200/books

Assuming that “books” is the Share Name as configured in TrueNAS.

38

So how about we just start from scratch with a new dataset and i’ll make a test user.

I can’t find a link to documentation so someone drop one if you know the right way to create > setup > grants permissions to a new dataset.

Just use a preset for “Open” permissions.

only options in the dataset preset are:

  • SMB
  • generic
  • apps
  • multiprotocol
