Modifiying existing files on the USB readyshare in EXT4 format through samba

[yanndan]

 Hello all,

I recently purchased this router for my home. I have plugged an USB drive of 4TB on it. This USB drive is composed of 2 partitions of 2TB each in EXT4 format. Previously, I used this USB drive on my former ISP router to backup my files. I would like to to the same with my netgear router.  All the partitions have write and read access without password configured on readyshare.

I use ubuntu/linux for all my computers at home. I can mount easily both drive with samba. I can add files or create new folders to the root of both partitions. However, I cannot modify or add files to the previous folders existing on the partitions. I tried a lot of different options for samba configuration and it is always the same.

 I checked with ls -l and all folders have the same owner and rights.

To illustrate my problem, I will give an example. Let's say I want to add a new file called new_file.txt.

My partitions is like:

PartitionI

- /OldFolder1

- /OldFolder2

...

- /OldFolderN

After my tests, my partition is now:

PartitionI

- /OldFolder1

- /OldFolder2

...

- /OldFolderN

- /NewFolder1

- - /Subfolder1

- - - new_file.txt

- - /Subfolder2

- - - new_file.txt

- - new_file.txt

- new_file.txt

When I tried to copy my new_file.txt to OldFolderX, I have a permission rejection. I checked with ls -l and all folders have the same owner and rights.

I am a bit lost right now about how to solve this issue. I hope someone can help me

Thanks in advance.

Best Regards,

yanndan

   Not much meat on that bone, but if you can write somewhere on a
shared file system, then I'd expect that you whould be able to write
anywhere without worrying about Samba options (subject to the usual
UID/GID/permission/ACL restrictions).  (Are there any ACLs involved?)

   It's nice that you're happy, but, as usual, showing actual
actions/commands with their actual results (output, error messages, LED
indicators, ...) can be more helpful than vague descriptions or
interpretations.

Dear all,

Thanks for your answer. I have currently the current option for samba:

guest,sec=ntlm,uid=1002,gid=100,rw,auto,vers=1.00 

I write below the commands I tried several times. I hope it gives you more information.

nas@XXX:~$ touch netgear_test.txt
nas@XXX:~$ cp -v netgear_test.txt /media/Backup_Pictures/
'netgear_test.txt' -> '/media/Backup_Pictures/netgear_test.txt'
nas@XXX:~$ cp -v netgear_test.txt /media/Backup_Pictures/Photos/
'netgear_test.txt' -> '/media/Backup_Pictures/Photos/netgear_test.txt'
cp: impossible de créer le fichier standard '/media/Backup_Pictures/Photos/netgear_test.txt': Permission non accordée
nas@XXX:~$ ll /media/Backup_Pictures/
