Weird share issue between QNAP and Ubuntu

Post by RichJacot » Tue Mar 23, 2021 4:27 am

Hello,

I'm having a weird issues an my Ubuntu 20.04 VM (running on the QNAP I'm discussing here)

I have several shares on the QNAP but the one I'm having issues with is a Media share.

In the shared folder permissions rjacot has Read/Write to the Media share.

On the QNAP itself:

[rjacot@TVS-672N Media]$ pwd
/share/CACHEDEV1_DATA/Media
[rjacot@TVS-672N Media]$ ll

The Ubuntu fstab looks like:

rjacot@ubuntu:/mnt/Media$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#

# / was on /dev/vda5 during installation

# /boot/efi was on /dev/vda1 during installation

//192.168.1.11/Music /mnt/Music cifs credentials=/home/rjacot/.smbcredentials5,uid=rjacot 0 0
rjacot@ubuntu:/mnt/Media$

The .smbcredentials1 file: (btw all of them are the same. Yes, I could have used the same file but I'm learning)

rjacot@ubuntu:~$ sudo cat .smbcredentials1
[sudo] password for rjacot:
user=rjacot
password=password Obviously I changed the real pw. ;-)
rjacot@ubuntu:~$


I can cd to my /mnt/Media and touch a file and it creates it. If I go to some of the subdirs in /mnt/Media, I CAN touch a file and some I cannot.

Here are some that work and some that don't.

rjacot@ubuntu:/mnt/Media$ touch ./TV/test
touch: cannot touch './TV/test': No such file or directory
rjacot@ubuntu:/mnt/Media$ touch ./Download/test
rjacot@ubuntu:/mnt/Media$ touch ./4k/test
rjacot@ubuntu:/mnt/Media$ touch ./Movies/test
touch: cannot touch './Movies/test': No such file or directory
rjacot@ubuntu:/mnt/Media$ rm ./Download/test ./4k/test
rjacot@ubuntu:/mnt/Media$

The permissions look right, the same on all subdirs. I don't understand why some subdirs are okay and some aren't.

Ideas or any other info I can provide?

TIA

Re: Weird share issue between QNAP and Ubuntu

I 'may' have found the issue.

I found spot in the QNAP shared folds section that has a dropdown for "Microsoft Networking Host Access" where I had to specify which hosts have this access. I did that and it's working again without a reboot. I'm not exactly sure why this "fixed" it but it is working again, without a reboot. Like I mentioned the QNAP shares Media and Movies is under that. If CIFS hosts weren't allowed, I don't know why I would write a file in Media and not Movies. Once it catches up on my automated downloads I'll reboot and confirm it's still working. To your point. On the NAS itself, rjacot is part of the admin group and the admin group has RW on the shared folders. admin is the owner and administrators is the group of all the shares on the QNAP. Media and subfolders have that same ownership so I'm confused.

On my Ubuntu VM, is there a better option instead of CIFS?
