Unable to write to mounted shared folder on linux

English Storage

I mounted a shared drive from my qnap qts. I even opened it all the way up to allow “guest access right: full access”. I am unable to write/delete items on that shared path. Here’s how it’s mounted on my client, and here’s how it looks in my /etc/fstab:

`/// on /mnt/smb type cifs (rw,relatime,vers=3.1.1,cache=strict,upcall_target=app,username=,uid=1000,forceuid,gid=1000,forcegid,addr=,file_mode=0755,dir_mode=0755,iocharset=utf8,soft,nounix,serverino,mapposix,reparse=nfs,rsize=4194304,wsize=4194304,bsize=1048576,retrans=1,echo_interval=60,actimeo=1,closetimeo=1,_netdev,x-systemd.automount)`

`///drive/ /mnt/smb/ cifs credentials=/etc/samba/cred-smb,iocharset=utf8,uid=1000,gid=1000,_netdev,nofail,x-systemd.automount 0 0`

The user I’m using does have read/write access.

Hi @userman39 ,

Thank you for sharing the details.

To better understand this issue, we may need to review the shared folder permission settings and the related mount information.

If possible, please share screenshots in this thread, but make sure to mask any sensitive information before posting them publicly, such as usernames, group names, IP addresses, domain names, NAS hostnames, shared folder names if they contain private information, full folder paths, serial numbers, email addresses, and any credential-related information.

Helpful information may include:

  1. The permission settings of the affected shared folder.

  2. Whether Advanced Folder Permissions or Windows ACL is enabled.

  3. The Linux CIFS mount configuration, with sensitive information removed or masked.

  4. The exact error message shown when writing to or deleting files from the mounted folder.

  5. The NAS model, QTS version, and Linux distribution/version.

If you are not sure whether the screenshots or configuration details contain sensitive information, we recommend opening a support ticket instead so our support team can review the details more securely:
